Abstract

The invention is directed to a process to prepare a gas oil product from a carbonaceous particles of a biomass source comprising the following steps:

(a) pyrolysis of the carbonaceous particles to a gaseous mixture of hydrocarbons in the absence of oxygen,(b) quenching the gaseous mixture of hydrocarbons by contacting with a liquid quench mixture of hydrocarbons having a lower temperature than the gaseous mixture thereby obtaining a rich liquid quench mixture and a quenched gas, and(c) isolating from the quenched gas a gas oil product by means of vacuum distillation, wherein the liquid gas oil is partly supplied to the top of the vacuum distillation column as a distillation reflux, partly used as part of the liquid quench mixture in (b) and partly discharged as the gas oil product.
