Al. Lapidus et al., ROLE OF CO-CATALYST COMPONENTS IN CARBON-MONOXIDE-ASSISTED ACETYLENE HYDROPOLYMERIZATION, Russian chemical bulletin, 43(3), 1994, pp. 355-359
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.
