【 摘 要 】

This is the first semi-annual progress report for the program 'Integrated High Temperature Coal to Hydrogen System with CO2 Separation'. The objective of the program is to develop a detailed design for a single high-temperature syngas-cleanup module to produce a pure stream of H2 from a coal-based system and to develop the new high-temperature membrane materials at the core of that design. The novel one-box process combines a shift reactor with a high-temperature CO2-selective membrane to convert CO to CO2, remove sulfur compounds, and remove CO2 in a simple, compact, fully integrated system. In the first six months of the program, a conceptual design for the one-box system was developed in Task 1 and the performance targets for the system and the membrane were evaluated. In Task 2.1 processes were developed for creating pore architectures in ceramics that are applicable to membrane structures. In Task 2.2, candidate materials were identified that have the potential for separation of CO2 and H2S at high temperatures.
