Title:
PROCESS TO PREPARE A CHAR PRODUCT AND A SYNGAS MIXTURE
Document Type and Number:
WIPO Patent Application WO/2019/054868
Kind Code:
A8
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.
