This Grant Opportunities for Academic Liaison with Industry (GOALI) research project will investigate the use of highly concentrated solar energy as a means of supplying a large amount of process heat at very high temperatures. The production of metals by carbothermal reduction of their oxides involves a high-temperature, energy-intensive process. The temperature required, in the range of 2100 - 2300 deg C, is at the upper limit for practical process heat addition from a combustion source alone. It is expected that when used for aluminum production a solar process would reduce the CO2 emissions from the aluminum industry, and the gas product would be CO rather than CO2. The expertise provided by the principle investigator and the Alcoa collaboration will be directed towards developing a creative and potentially revolutionary reactor and process concept that could have significant implications for the manufacture of the more exotic, difficult to extract materials, as well as aluminum. Experimental work will be conducted at the Institute for Materials and Processes solar test facility in Odeillo, France.

该学术与工业联络资助机会 (GOALI) 研究项目将研究使用高度集中的太阳能作为在极高温度下提供大量工艺热量的手段。 通过碳热还原氧化物来生产金属涉及高温、能源密集型过程。 所需温度在 2100 - 2300 摄氏度范围内，是单独从燃烧源添加实际工艺热量的上限。预计当用于铝生产时，太阳能工艺将减少铝工业的二氧化碳排放，并且气体产物将是二氧化碳而不是二氧化碳。首席研究员和美国铝业公司合作提供的专业知识将用于开发一种具有创造性和潜在革命性的反应器和工艺概念，这可能对更奇特、难以提取的材料以及铝的制造产生重大影响。实验工作将在法国奥代约的材料与工艺研究所太阳能测试设施进行。
