Experimental results showed that 385℃ was the suitable temperature for production of gasoline. At this temperature, conversion of>180℃ distillate reached 89w%, and a 87w% yield of gasoline fraction was obtained with 2.9 w% hydrogen consumption.The composition and properties of hydrocracking products were also analyzed in detail. The quality of the gasoline fraction met RQ-75(GB484-77) specificatio(?0 substantially with octane number 75. The gasoline fraction is capable of producing high-octane blend by reforming.Possessing more than 75w% of potential aromatic content and less than 0.5ppm of nitrogen content, the C_6-145℃ product is an excellent BTX reforming stocks.
