Co-processing biomass derivatives with vacuum gasoil through hydrocracking

Abstract

RMN+CATREN:ING+CLO:CGE:YSCInternational audienceFossil fuel demand is continuously increasing, particularly in the field of transport, where light petroleum products and middle distillate products are used. The transformation of the heavy oil cuts into middle distillate fuel is essential to meet current and future demand for fuels. The most widely consumed products, such as diesel, can be produced by hydrocracking reactions [1]. On the other hand, the development of new generations of non-fossil fuels, such as biomass derivatives, is of great interest [2]. Co-processing VGO (Vacuum Gas Oil) with bio-oil has been investigated in a few studies [3]. The aim of this work is to shed light on the impact of bio-liquids on the hydrocracking reactions with mineral feed into middle distillates. We studied various bioliquids coming from wood biomass having undergone different treatments like stabilized pyrolysis oil (SPO) or hydrothermal liquefaction (HTL). The study evaluates, in a semi-batch reactor under hydrogen pressure, the performance of sulfide catalysts in the presence of a bio-liquid-VGO (Vacuum Gas Oil) mixture
