Abstract
The results of the study of the effect of the concentration of propylene to propane-propylene fraction to a liquid yield of the reaction depending on the feed space velocity are presented.The results in the presence of a chromia-alumina catalyst in oxides of Ni, Co, Cr are examined.The optimal reaction conditions (Т-2800С, Voverall velocity 50-200 h-1), in which the liquid yield of the reaction was determined depending on the concentration of С3Н8 and С3Н6 in the raw feedstock, were set.
Highlights
One of the most important tasks of oil refining from both the environmental as well as economic points of view is the effective use of hydrocarbon residue gas of refineries and the chemical industry for the production of light oil products and raw materials for the petrochemical industry
The purpose of this study is to investigate the activity of the chromia-alumina catalyst promoted with oxides of Ni, Co, Cr and study of the effect of the concentration of propylene to propane-propylene fraction to a liquid yield of the reaction depending on the feed space velocity
We have found that in the catalyst subjected to calcination under vacuum at a temperature 500-5500С, NiAl2O4 and CoAl2O4 are formed, presence of which leads to formation of olefins by dehydrogenation of the corresponding paraffins
