Early life and education

Trevor Alan Hatton was born in Durban, South Africa. [2] He earned his B.Sc. Eng. (1972) and M.Sc. Eng. (1976) degrees at the University of Natal, Durban. He then worked for the Council for Scientific and Industrial Research in Pretoria for three years. Hatton earned his Ph.D. from the University of Wisconsin–Madison, in 1981, [3] working with Edwin N. Lightfoot. [4]

Career

Hatton joined the Massachusetts Institute of Technology (MIT) in 1982. [5] For several years he and his wife Marianne were faculty residents, living at MacGregor House until 1986. [6] [7] [8]

In 1995, Ralph Landau established a new chair at MIT: the Ralph Landau Professorship of Chemical Engineering Practice, to be held by the Director of the David H. Koch School of Chemical Engineering Practice. [9] T. Alan Hatton became the first Ralph Landau Professor of the Practice School in 1996. [10] At the Practice School, students complete placements at industrial projects with international host companies, as well as taking on-campus academic courses. [11] [12] Hatton has been the program director of the Practice School for over 28 years. [2]

Beginning in 2015, the MIT Energy Initiative has established eight low-carbon energy centers focusing on technical advancements in areas critical for climate change. [1] [13] Hatton co-directs the Center for Carbon Capture, Utilization and Storage. [1]

Hatton holds an honorary professorship at the University of Melbourne [14] and is an adjunct professor at Curtin University in Perth, Australia. [15]

He has served as a co-editor of Colloids and Surfaces , [16] and is on the international advisory board of the Chinese Journal of Chemical Engineering. [17] In 1990, he chaired the Gordon Research Conference on Separation and Purification. [18] In 1999, he co-chaired the 73rd Colloid and Surface Science Symposium, held at MIT, with Paul E. Labinis. [19]

Research

Hatton has published widely on colloidal phenomena and their applications in chemical processing. His research interests include responsive surfactants and gels obtained by colloidal self-assembly, stimuli-responsive materials, chemically reactive fibers and fabrics, metal-organic frameworks for separations and catalysis, and synthesis and functionalization of magnetic nanoparticles and clusters. [20]

Much of his work focuses on the development of purification technologies of various kinds. In the 1980s, he studied the effects of metal ions, clays, and minerals on sorption capacities. [21] In the 1990s, Hatton worked to develop solvents for chemical synthesis, separation and cleaning that were less volatile and less water-soluble. This decreased the potential for undesirable air emissions or aqueous discharge. [22]

Hatton has done considerable work on the use of magnetically sensitive nanoparticles for separation of liquids. Nanoparticles can be designed with a distinctive protein signature that will attract and attach a desired target protein. The nanoparticles can then be added to a suspension, where they will attach the target molecules. By subjecting the liquid to a magnetic field, the nanoparticles with their attached targets can be removed from the suspension. Finally the nanoparticles and proteins can be separated, recovering the nanoparticles for reuse. [20] Hatton has used this type of technique for the separation of oil from water. He hopes it may be used eventually for the cleaning up of oil spills. [23]

As of 2012, Hatton worked on electrochemically mediated methods of carbon capture and conversion which could be used to reduce emissions from power plants and industry and decrease greenhouse gases. The researchers are studying magnesium oxide-based materials, coating particles of MgO with alkali metal nitrates. The resulting materials can capture more than ten times as much carbon dioxide (CO2) as other materials being investigated, at lower temperatures. [24]

As of 2015, T. Alan Hatton and Aly Eltayeb received funding to develop a commercial prototype for carbon capture and storage from the smokestacks of industrial and power plants that burn fossil fuels. First, flue gases are passed through a liquid containing amines, which attract carbon dioxide. Then, building on the work of Michael Stern, the prototype passes the resulting solution through an electrochemical cell containing two electrically charged copper plates. This causes the amines to release the carbon dioxide, which can be sequestered or reused. The approach would remove carbon from the atmosphere, while using less electricity than current amine scrubber technology. [25] [26]

As of 2016, Yogesh Surendranath and T. Alan Hatton received a Seed Fund Grant from the MIT Energy Initiative to investigate the possible cycling of carbon dioxide (CO2) emissions into chemical fuel. [27]

With Xiao Su and others, Hatton has developed new methods of removing unwanted substances such as chemical waste, pesticides, and pharmaceuticals from water supplies. Both positive and negative electrodes or plates can be coated with Faradaic materials, which are chemically "functionalized" to react with specific molecules. As water flows between the plates, electricity is applied causing the active groups on the plates to combine with desired molecules. This process can work even with very small trace concentrations of target particles, present at parts-per-million. For their work on water purification, researchers won the 2016 Water Innovation Prize. [28] [29] By better understanding fundamental mechanisms involved in electrosorption, they are attempting to design more effective novel electrode materials. [5]

<span class="mw-page-title-main">Carbon capture and storage</span> Collecting carbon dioxide from industrial emissions

Carbon capture and storage (CCS) is a process in which a relatively pure stream of carbon dioxide (CO2) from industrial sources is separated, treated and transported to a long-term storage location. For example, the carbon dioxide stream that is to be captured can result from burning fossil fuels or biomass. Usually the CO2 is captured from large point sources, such as a chemical plant or biomass plant, and then stored in an underground geological formation. The aim is to reduce greenhouse gas emissions and thus mitigate climate change. The IPCC's most recent report on mitigating climate change describes CCS retrofits for existing power plants as one of the ways to limit emissions from the electricity sector and meet Paris Agreement goals.

Enhanced oil recovery, also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. Although the primary and secondary recovery techniques rely on the pressure differential between the surface and the underground well, enhanced oil recovery functions by altering the chemical composition of the oil itself in order to make it easier to extract. EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery. According to the US Department of Energy, carbon dioxide and water are injected along with one of three EOR techniques: thermal injection, gas injection, and chemical injection. More advanced, speculative EOR techniques are sometimes called quaternary recovery.

Hydrogen gas is produced by several industrial methods. Fossil fuels are the dominant source of hydrogen. As of 2020, the majority of hydrogen (~95%) is produced by steam reforming of natural gas and other light hydrocarbons, and partial oxidation of heavier hydrocarbons. Other methods of hydrogen production include biomass gasification and methane pyrolysis. Methane pyrolysis and water electrolysis can use any source of electricity including renewable energy.

As the world's energy demand continues to grow, the development of more efficient and sustainable technologies for generating and storing energy is becoming increasingly important. According to Dr. Wade Adams from Rice University, energy will be the most pressing problem facing humanity in the next 50 years and nanotechnology has potential to solve this issue. Nanotechnology, a relatively new field of science and engineering, has shown promise to have a significant impact on the energy industry. Nanotechnology is defined as any technology that contains particles with one dimension under 100 nanometers in length. For scale, a single virus particle is about 100 nanometers wide.

Green nanotechnology refers to the use of nanotechnology to enhance the environmental sustainability of processes producing negative externalities.

Magnetic nanoparticles are a class of nanoparticle that can be manipulated using magnetic fields. Such particles commonly consist of two components, a magnetic material, often iron, nickel and cobalt, and a chemical component that has functionality. While nanoparticles are smaller than 1 micrometer in diameter, the larger microbeads are 0.5–500 micrometer in diameter. Magnetic nanoparticle clusters that are composed of a number of individual magnetic nanoparticles are known as magnetic nanobeads with a diameter of 50–200 nanometers. Magnetic nanoparticle clusters are a basis for their further magnetic assembly into magnetic nanochains. The magnetic nanoparticles have been the focus of much research recently because they possess attractive properties which could see potential use in catalysis including nanomaterial-based catalysts, biomedicine and tissue specific targeting, magnetically tunable colloidal photonic crystals, microfluidics, magnetic resonance imaging, magnetic particle imaging, data storage, environmental remediation, nanofluids, optical filters, defect sensor, magnetic cooling and cation sensors.

An electrocatalyst is a catalyst that participates in electrochemical reactions. Electrocatalysts are a specific form of catalysts that function at electrode surfaces or, most commonly, may be the electrode surface itself. An electrocatalyst can be heterogeneous such as a platinized electrode. Homogeneous electrocatalysts, which are soluble, assist in transferring electrons between the electrode and reactants, and/or facilitate an intermediate chemical transformation described by an overall half reaction. Major challenges in electrocatalysts focus on fuel cells.

Carbon-neutral fuel is fuel which produces no net-greenhouse gas emissions or carbon footprint. In practice, this usually means fuels that are made using carbon dioxide (CO2) as a feedstock. Proposed carbon-neutral fuels can broadly be grouped into synthetic fuels, which are made by chemically hydrogenating carbon dioxide, and biofuels, which are produced using natural CO2-consuming processes like photosynthesis.
