ROLE OF CO-CATALYST COMPONENTS IN CARBON-MONOXIDE-ASSISTED ACETYLENE HYDROPOLYMERIZATION

The carbon monoxide-assisted interaction of acetylene with hydrogen ov er cobalt catalysts was studied. The role of particular components of the catalyst was revealed. The influence of the compositions of both t he initial gas and the catalytic system on the yield and composition o f liquid hydrocarbons was studied. The mechanism of the process was in vestigated by IR-spectroscopy, pulse chromatography, and the radiochem ical method. It was proposed that acetylene adsorbed on the support is polymerized with the participation of hydrogen, whereas acetylene ads orbed on the metal takes part in hydrogenation and hydrocracking proce sses. Carbon monoxide creates additional active sites for the growth o f hydrocarbon chains.
