Abstract: Modification of the composition and structure of LaCoO3 allows to vary the phisicochemical properties. The use of KIT-6 silica significantly increased the activity of the samples; however, it is insufficient in comparison with the conventional CoAl catalyst syngas conversion. Substitution of Co3+ for Ti4+ as well as the use of KIT-6 increases the cobalt reduction temperature to 670-730°C. Substitution of La3+ for Ca2+ reduces the selectivity to methanol while significantly increasing the yield of light C2-8 hydrocarbons. The selectivity for methane and alcohols C2+-alcohols does not change.
