Impact of processing different blends of heavy gas oil and light cycle oil in a mild hydrocracker unit

摘要

This mild hydrocracking study is focused on processing of heavy gas oil (HGO), light cycle oil (LCO) and blends of HGO and LCO in different concentrations over commercially available catalysts in a pilot plant having two-stage processing configuration. The performance of the catalysts has been verified for two different stuations. The first one is with feed blend maximizing HGO and second with feed blend maximizing LCO, both targeting 100% product yield. The effect of changes in feedstock blends, temperature, pressure, LHSV, and H-2/HC ratio is discussed in this paper. The impact of product quality from different feedstock blends have been ascertained by comparing the base case data from the commercial unit and also the equipment design limits are taken into consideration.
