FIELD: chemistry.
SUBSTANCE: disclosed the catalyst for the light paraffin hydrocarbons dehydrogenation, which is the chromium oxide, supported on alumina, at that the chromic oxide in the amount of 15-23 wt % is in the dispersed X-ray amorphous state. Also described the method of production the unsaturated hydrocarbons by dehydrogenation the corresponding paraffin hydrocarbons in the flow reactor with the fixed bed catalyst of volume ~ 1 cm3 when the paraffinic hydrocarbon is supplied at the rate of 420 h-1 and the process temperature 570°C, which is realized, using the above described catalyst, and the catalytic cycle is carried out for 31-136 minutes, including the dehydrogenation for 15-120 minutes.
EFFECT: increase of the process productivity due to the increase of the dehydrogenation stage time and, correspondingly, the increase in the total yield of the unsaturated hydrocarbon per one dehydrogenation-regeneration-activation cycle.
