INFLUENCE OF MODE PARAMETERS ON HYDROCRACKING OF GOUDRON WITH SUSPENDED NANOSIZED CATALYSTS

Abstract

 Hydrocracking of a goudron mixture from Baku oils was studied at low pressure in the presence of a suspended nanosized catalyst to increase the amount of light oil and to advance the oil refining. Kaolinite was used as a catalyst in an amount of 1,0–2,5 % by weight of the goudron. The effect of temperature and pressure on the reaction yield was studied. It was shown that with an increase in temperature from 400 to 450 °C (pressure 0,5 MPa), the yield of light oil increased from 35 to 61 wt.%. An increase in pressure from 0,5 to 6,0 MPa led to an increase in the yield of light oil from 47,0 to 58,8 wt.%. Nanoscale catalyst systems demonstrated the advantage over supported catalysts in the possibility of a more efficient processing of raw materials of very low quality under milder conditions, which indicates the economic profitability of the proposed process.
