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 conductedatthe 2Egyptian Petroleum Research Institute3. Waste cooking oil (WCO) feedstock was acquired and collected from daily home use.Waste lube oil was sampled from 2Suez Oil Processing Company3.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 diesel product quality (cetane index)
