Abstract
The invention is directed to a process to continuously prepare a gas oil product from carbonaceous particles of a biomass source comprising the following steps. (a) contacting carbonaceous particles with a hydrogen comprising gas in a fluidised bed reactor in the absence of oxygen and in the absence of a catalyst, at an average solids residence time of between (20) and (120) seconds and at thermal conversion conditions to obtain a gaseous mixture comprising of hydrocarbons and char particles. (b) discharging the char particles and the gaseous mixture separately from the fluidised bed reactor. And (c) isolating from the gaseous mixture a gas oil product by means of distillation.

- (c) isolating from the gaseous mixture a gas oil product by means of distillation.
A process to continuously prepare a gas oil product from carbonaceous particles of a biomass source comprising the following steps,
- (a) contacting carbonaceous particles with a hydrogen comprising gas in a fluidised bed reactor in the absence of oxygen and in the absence of a porous heterogeneous catalyst onto which one or more metals of Group 6, Group 9 or Group 10 of the Table of Elements are incorporated, at an average solids residence time of between 20 and 120 seconds and at thermal conversion conditions to obtain a gaseous mixture comprising of hydrocarbons and char particles,
- wherein the fluidised bed reactor comprises a bubbling fluidising bed of the carbonaceous particles to which fluidising bed the hydrogen comprising gas is supplied from below the fluidising bed as a fluidising gas and from which fluidising bed the gaseous mixture is discharged upwardly and away from the fluidising bed and the char particles are discharged from the bubbling fluidising bed of the carbonaceous particles,
- (b) discharging the char particles and the gaseous mixture separately from the fluidised bed reactor, and
- (c) isolating from the gaseous mixture a gas oil product by means of distillation.
