PROCESS FOR THE CATALYTIC CRACKING OF PYROLYSIS OILS

摘要

The present invention provides a process for catalytic cracking of a pyrolysis oil derived from material comprising lignocellulose, comprising the steps of a) subjecting a feed comprising the pyrolysis oil to a hydrodeoxygenation step to obtain a product stream comprising a partially deoxygenated pyrolysis oil; b) separating the partially deoxygenated pyrolysis oil having an oxygen content of from 5 to 30 wt% from the product stream obtained in a); c) contacting the partially deoxygenated pyrolysis oil obtained in b) in the presence of a hydrocarbon feed derived from a mineral crude oil with a cracking catalyst under catalytic cracking conditions to obtain a deoxygenated and cracked product stream; and d) separating at least one product fraction from the product stream obtained in c).
