9. CATALYSIS

 

About 90 percent of chemical manufacturing processes and more than 20 percent of all industrial products in the U.S. employ underlying catalytic steps.  For petroleum refining, over 80 percent of the processes involve catalysis.  Catalysis also plays a substantial role in the production of 30 of the top 50 U.S. commodity chemicals.  Of the remaining 20, six more are made from raw materials produced catalytically.  The energy use component in the production of the top 50 chemicals is significant – 5 quadrillion BTUs per year – 3 quadrillion BTUs per year for those with catalytic production routes.  It has been estimated that if all the catalytic processes associated with petroleum refining and with chemical manufacture of the top 50 chemicals were raised to their maximum yields, total energy savings would exceed one quadrillion BTUs per year.  More efficient chemical production, resulting from improvements to catalytic processes, would also contribute to significantly reduced carbon emissions.  This topic seeks to accelerate the catalyst discovery and application process by identifying catalysts that have higher selectivities, can operate at modest temperatures and pressures, and contribute to a reduction in the number of unit operations.  It is intended that R&D be conducted to overcome current limitations of selectivity and efficiency, leading to substantial energy savings, improved economic performance, enhanced utilization of feedstocks, and reduced requirements for materials of construction.

 

Grant applications must address the potential public benefits that the proposed technology would provide from:  (1)  reduced energy consumption; and (2) the reduction in materials consumption, water consumption, and/or toxicity/pollutant dispersion.  Grant applications also should include a plan for introducing the new technology into the US chemical and petroleum refining industries (i.e., those using natural gas, natural gas liquids, and petroleum derivative feedstocks), in order to access capabilities for widespread technology dissemination. 

 

Grant applications are sought only in the following subtopics:

 

 

a. Heterogeneous Catalysis—Catalytic reforming, catalytic cracking, hydrocracking, alkylation, isomerization, and the conversion of methanol into olefins are some of the most important industrial applications of heterogeneous catalysis, in chemical manufacturing and petroleum refining.  For example, the synthesis of oxygenated compounds from hydrocarbons involves heterogeneous oxidation catalysis, the cracking of paraffins to olefins, and the subsequent direct or indirect addition of oxygen.  In such processes, the direct addition of oxygen to olefins is exothermic, and, therefore, increased selectivity would provide energy savings from reduced hydrocarbon feedstock requirements.  Indeed, the enhancement of oxidation selectivity represents the largest potential improvement of energy efficiency in the chemical industry (Parshall, 1994).  Grant applications are sought for the research and development of technologies for improving the efficiency of industrial catalytic oxidations, reductions, and acid-base catalysis.  Areas of particular interest are:  (1) selective oxidation of petroleum feedstocks for commodity chemicals, thereby enhancing efficiency by reducing over-oxidation; (2) alkane activation for direct oxidation with molecular oxygen, e.g., in the conversion of methane to methanol; (3) heat integration of catalytic oxidations with other processes; (4) improvements in the syntheses or use of reactive intermediates; (5) new catalysts for commodity chemical reductions including ammonia synthesis from elemental gases, fuel and gas reforming catalysts, and cathodic catalysts for fuel cells – new ideas for fuel cell catalysts for oxygen activation are of particular interest; and (6) new and improved catalysts for petroleum cracking in a fluidized bed, as well as new heterogeneous catalysts for alkene/alkane alkylation.

b. Homogeneous CatalysisIsomerizations, hydrogenations, oxidations, polymerizations, and esterifications are just a few of the many commercial applications of homogeneous catalysis.  The DOE has a long and respected history of support for the development of homogeneous catalysts used for polymer syntheses, as well as homogenous catalysts used for chemical synthesis from synthesis gas.  Grant applications are sought for the development of new homogeneous catalysts for these applications, especially homogeneous catalysts that avoid the use of precious metals such as rhodium.

c. Reactive SeparationsThe integration of catalysts with separation technologies – for example, reactive distillations and catalytic membranes – could lead to improvements in energy efficiency.  However, the tendency of homogeneous catalysts to dissolve in reaction media limits catalyst stability (and therefore their use) when the homogeneous catalysts are fixed to a membrane.  Grant applications are sought for research and development that will overcome the technical barriers to the use of catalysts in reactive separations technology.
