Conversion of the propane-butane mixture at presence Pt-containing zeolite catalyst is researched at 300-500°C. It is shown that with increase in temperature of carrying out of process the yield of aromat­ic hydrocarbons, the maximum quality aromatics Ce-Ce increases reaches 40.0%wt at 500°C and a feed space velocity of raw materials 100 lr1. Conversion butanes thus reach is 94.0%.

The production of various motor fuels is carried out by processing light fractions of oil with an initial temperature of boiling to 350°С. The current trend shows that oil in new fi elds has more weight than before. New oil reservoirs are deeper with a greater proportion of dark fraction with a boiling point of 350°С. This situation stimulates to fi nd new ways of increasing the processing depth light fractions for synthesis target product. One of the main solution path for the problem is creation of new catalytic systems or modernization of existing ones.
