Abstract: The invention is directed to a process to prepare a char product and a syngas mixture comprising hydrogen and carbon monoxide from a solid biomass feed comprising the following steps: (i) performing a continuously operated partial oxidation of the solid biomass feed at a gas temperature of between 700 and 1100° C. and at a solids residence time of less than 5 seconds, (ii) continuously separating the formed char particles as the char product from the formed gaseous fraction and (iii) subjecting the gaseous fraction obtained in step (ii) to a continuously operated partial oxidation and/or to a steam reforming to obtain the syngas mixture. The solid biomass feed has been obtained by torrefaction of a starting material comprising lignocellulose and is a sieve fraction wherein 99 wt % of the solid biomass particles is smaller than 2 mm.

Abstract: 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.

Abstract: The invention is directed to a process to prepare an activated carbon product and a gaseous fraction comprising hydrogen, carbon monoxide and a mixture of gaseous organic compounds 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 solids fraction from the gaseous fraction. and (iii) activating the char particles as obtained in step (ii) to obtain the activated carbon product.
