A heat treatment apparatus has a first screw conveyor, a second screw conveyor, a first nozzle pipe, and a second nozzle pipe. If the first screw conveyor rotates right, the first nozzle pipe is disposed on the left lateral side of the first screw conveyor. If the first screw conveyor rotates left, the first nozzle pipe is disposed on the right lateral side of the first screw conveyor. If the second screw conveyor rotates right, the second nozzle pipe is disposed on the left lateral side of the second screw conveyor. If the second screw conveyor rotates left, the second nozzle pipe is disposed on the right lateral side of the second screw conveyor.

A system and method for torrefying a combination of biomass and biochar colloidal dispersion is provided.

The invention is directed to a process to prepare a char product and a syngas mixture comprising hydrogen and carbon monoxide from a solid torrefied biomass feed comprising the following steps: (i) subjecting the solid biomass feed to a pyrolysis reaction thereby obtaining a gaseous fraction comprising hydrogen, carbon monoxide and a mixture of gaseous organic compounds and a solid fraction comprising of char particles; (ii) separating the char particles as the char product from the gaseous fraction; (iii) subjecting the gaseous fraction obtained in step (ii) to a continuously operated partial oxidation to obtain a syngas mixture further comprising water and having an elevated temperature and (iv) contacting the syngas mixture with a carbonaceous compound to chemically quench the syngas mixture. The temperature of the syngas is reduced in step (iv) from between 1000 and 1600° C. to a temperature of between 800 and 1200° C.
