Mechanistic and kinetic studies of high-temperature coal gas desulfurization sorbents. Quarterly technical progress report No. 4, April-June 1989.

摘要

A much more detailed study was performed during this quarter of the reactions involved in the reduction of ZnO-TiO2 sorbents which were briefly discussed in our first quarterly report. As before, the findings pertaining to ZnO-TiO2 systems will be compared with the reduction of ZnO under similar experimental conditions. The objectives of this study were to investigate the mechanisms and kinetics of sorbent ZnO-TiO2 as a function of the following parameters: (1) Zn/Ti sorbent ratio; (2) reduction temperature; (3) H2 concentration. 18 refs., 10 figs., 2 tabs.
