CO-HYDROPROCESSING AND HYDROCRACKING OF ALTERNATIVE FEED MIXTURE (VACUUM GASOIL/USED LUBRICATING OIL/WASTE COOKING OIL) FOR PRODUCTION OF HIGH-QUALITY FUELS

Abstract

The aim of this thesis was to make a semi complete study about co-hydroprocessing of vacuum gasoil (VGO), waste cooking oil (WCO) and waste lube oil (WLO). This alternative feed mixture is studied under different reaction temperature and different mixture feed compositions, then industrial calibrated simulation case of hydrocracking unit is built to illustrate the effects new unconventional feed on unit integration and economics. Experimental work was conducted at the “Egyptian Petroleum Research Institute”. Waste cooking oil (WCO) feedstock was acquired and collected from daily home use. Waste lube oil was sampled from “Suez Oil Processing Company”. Vacuum gasoil (VGO) feedstock was acquired from Middle East Oil Refinery (MIDOR) in Alexandria, Egypt. The target of the experimental work is to determine the effect of feed mixture composition and reaction temperature on high-quality product fuels. The obtained results revealed that: adding WCO increases the reaction conversion and jet fuel yield, while adding WLO increases
