TITLE: Deactivation by carbon of iron catalysts for indirect liquefaction. Quarterly technical progress report, December 16, 1989-March 15, 1990. AUTHOR: C. H. Bartholomew. INST.

NTIS ORDER NO.: DE91002417INW ABSTRACT: This report describes recent progress in a fundamental, three-year investigation of carbon formation and its effects on the activity and selectivity of promoted iron catalysts for synthesis, the objectives of which are: determine rates and mechanisms of carbon deactivation of unsupported Fe and Fe/K catalysts during CO hydrogenation over a range of CO concentrations, CO:H(sub 2) ratios, and temperatures; model the rates of deactivation of the same catalysts in fixed-bed reactors. During the fourteenth quarter design of software for a computer-automated reactor system to be used in the kinetic and deactivation studies was continued. Further progress was made toward the completion of the control language, control routines, and software for operating this system. Progress was also made towards testing of the system hardware and software. 47 refs. REPORT NUMBER: DOE/PC/90533-14 CONTRACT NUMBER: FG22-86PC90533 |
