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 FT 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 rage 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 fifth quarter further progress was made in the construction of a computer-automated reactor system to be used in the kinetic and deactivation studies. A new HP5890 chromatograph was received, tested and instaled for this system. Modifications were made to the fixed bed reactor system to enable the H sub 2 and CO partial pressures to be varied systematically. 47 refs. (ERA citation 13:024230)
