【 摘 要 】

The objective of the research project was to determine the feasibility of a simpler, more energy-efficient process for the production of 95+% H{sub 2} from natural gas, and to collect sufficient experimental data on the effect of reaction parameters to guide additional larger-scale process development. The overall objectives were accomplished. 95+% H{sub 2} was produced in a single reaction step by adding a calcium-based CO{sub 2} acceptor to standard Ni-based reforming catalyst. The spent acceptor was successfully regenerated and used in a number of reaction steps with only moderate loss in activity as the number of cycles increased. Sufficient experimental data were collected to guide further larger-scale experimental work designed to investigate the economic feasibility of the process.
