A calcium oxide sorbent process for bulk separation of carbon dioxide. Quarterly progress report 19, January--March, 1994
This research project is investigating the technical feasibility of a high-temperature, high-pressure (HTHP) process for the bulk separation of CO{sub 2} from coal-derived gas. Indirect evidence which suggested that the water-gas shift reaction occurred simultaneously with CO{sub 2} removal was found. Occurrence of the simultaneous reactions created the possibility of a direct one-step process for the manufacture of hydrogen from coal-gas while at the same time separating a concentrated stream of CO{sub 2}. Previous quarterly reports have described the design, construction, and commissioning of the fixed-bed reactor, development of analytical procedures, and results of a number of tests using dolomite sorbent precursor. During the current quarter, additional tests were carried out to study the effects of calcination gas composition, temperature, and space velocity using the standard dolomite sorbents. Alternate sorbents were tested to provide direct comparison of dolomite and limestone performance. Tests were performed using an empty reactor and reactor packed with commercial shift catalyst to learn more of the characteristics of the shift reaction in the absence of carbonation. Toward the end of the quarter, emphasis changed to sorbent durability and a number of multicycle tests were completed.
