According to foreign media reports , Southwest Research Institute （Southwest Research Institute,SwRI） And the University of Texas at San Antonio （The University of Texas at San Antonio,UTSA） Cooperate to combine two catalytic processes into one reactor , Aimed at CO2 Carbon is recovered from to produce low-cost hydrocarbon fuels . This work is carried out by SwRI From powertrain engineering Grant Seuser Doctor and UTSA From the school of engineering Gary Jacobs Doctoral leader , Get... Together Connecting through Research Partnerships（Connect） Project 125,000 beautiful element funding .
Due to the increasing demand for energy and transport in developing countries , Expect to 2040 Greenhouse gas emissions will increase by about 17%.Seuser call ：“ We lack renewable fuels and technologies to provide cleaner power generation . With the increasing number of battery powered passenger cars , Is expected in the future , aviation 、 Locomotive 、 The shipping and long-distance truck transportation industry increasingly needs high energy density hydrocarbons to meet high power demand .”
Seuser and Jacobs It is proposed to use a gas called carbon dioxide （CO2） Hydrogenation process to produce cleaner renewable liquid hydrocarbon fuels for transportation . To achieve this goal , They plan to build a single reactor that can perform two chemical processes in one step . The first chemical process is to combine hydrogen with CO2 The reaction produces carbon monoxide （CO）, The second chemical process is through Fischer Tropsch synthesis （Fischer-Tropsch synthesis）, take CO And hydrogen （ Syngas or mixture of syngas ） Conversion to liquid hydrocarbon fuel .
Jacobs call ：“ About a century ago , Fischer Tropsch synthesis process was first invented in Germany , And is still in South Africa and Quatar And other areas , Convert coal and natural gas into liquid hydrocarbon fuel , The factory capacity ranges from tens of thousands of barrels to hundreds of thousands of barrels a day . However, there are still challenges in integrating this catalytic technology into the process of using carbon dioxide in raw materials .”
Besides ,SwRI-UTSA The process developed by the team will be able to use carbon dioxide captured in fossil fuel power plants , Otherwise, these carbon dioxide will be isolated underground or discharged into the atmosphere .Jacobs call ：“ The functions of the two catalytic processes 、 Reverse water gas shift （reverse water-gas shift） And Fischer Tropsch synthesis are combined into one reactor , So as to simplify the process and improve its economic feasibility .”
This work will also explore the combination of reverse water gas shift and Fischer Tropsch success A new type of catalyst .Jacobs Will be in UTSA Create and characterize these functions , and Seuser Will be in SwRI Catalysts are used in reactors to evaluate their industrial feasibility .Seuser call ：“ Reducing the complexity of converting carbon dioxide into hydrocarbon fuels will have a significant impact . To prevent the earth's temperature from rising further , Finding a way to produce low-carbon fuels and maintain the current energy infrastructure is crucial .”
