Biodiesel Produced by Two Step Hydroprocessing of Waste Cooking Oil 1. Hydrotreating of waste cooking oil and straight run gasoil mixture

摘要

This paper presents the research aimed to use waste cooking oil (WCO) for biofuel production. The experiments consist of hydrotreating mixtures straight run gas oil (SRGO) with WCO 5%, 7,5%, 10% at 360 degrees C and 380 degrees C temperatures, 60 bar pressure, liquid hourly space velocity (LHSV) of 1h(-1) in the presence of catalyst Co-Mo/gamma Al2O3. The research has focused on the influence of temperature and the WCO/SRGO ratio on the yields and the physicochemical properties of the biofuel obtained. The research findings highlight the good characteristics of biofuel that fit with the requirements of EN 590, except the pour point and sulfur content.
