ABSTRACT:

This report describes the work carried out during the project period from December 1, 1985 through February 28, 1986. The results of our investigations on a series of cobalt and cobalt thoria catalysts physically admixed with the medium pore zeolite ZSM-5 are presented.  The preparation of the catalysts and the catalytic measurements were carried out at the Pittsburgh Energy Technology Centre of the Department of Energy and the Zero-field Nuclear Magnetic Resonance experiments were made at Grambling State University using a modified Wilks Nuclear Quadrupole Resonance spectrometer, described in the previous report. The catalytic measurements revealed that the hydrocarbon yields increase from about 35% to 60% as the cobalt metal loading in ZSM-5 increases from 3 wt % to 9 wt %. When a small amount of the promoter Thoria (0.4 wt %) is added, the hydrocarbon yields increased significantly (by about 25%), for the same weight percents of cobalt in Co-ZSM-5. The primary objective of our project is to examine the effect on the Ferromagnetic character of the cobalt metal due to the (1) concentration of Co metal in ZSM-5, (2) presence of the promoter Thoria, and (3) catalytic activity. 12 refs.
