    Abstract: The invention is directed to a process to prepare a char product by pyrolysis or mild gasification of a solid biomass feed thereby obtaining a gaseous fraction comprising hydrogen, carbon monoxide and a mixture of gaseous organic compounds and a solid fraction comprising of char particles having a reduced atomic hydrogen over carbon ratio and a reduced oxygen over carbon ratio relative to the solid biomass feed. The solid biomass feed are pellets of a solid torrefied biomass feed. The pyrolysis or mild gasification is performed at a temperature of between 500 and 800° C. and at a solid residence time of between 10 and 60 minutes.

    Abstract: The invention is directed to a process to prepare ethylene and propylene from a biomass feedstock wherein the process comprises the following steps: (a) a mild gasification of a torrefied biomass feedstock thereby obtaining a char and a gaseous fraction comprising hydrogen, carbon monoxide and a mixture of gaseous organic compounds; (b) a severe gasification of the gaseous fraction in the absence of the char to obtain a substantially tar-free syngas; (c) a Fischer-Tropsch reaction of the substantially tar-free syngas to obtain a first product mixture comprising of methane and C2+ aliphatic hydrocarbons, and (d) a steam cracking reaction of all or part of the C2+ aliphatic hydrocarbons obtained in step (c) to obtain a second product mixture. Methane as isolated from the first and/or the second product mixture may be combusted to generate heat for the endothermal steam cracking reaction in step (d).

    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 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 continuously prepare a char product having a high BET surface area of above 400 m2/g and gaseous fraction comprising of carbon monoxide, hydrogen and hydrocarbons starting from particles of a torrefied biomass in an elongated and substantially horizontally positioned reactor furnace. A reactive gaseous mixture of steam and oxygen is supplied to the solids in the reactor and more oxygen and steam is supplied to the downstream end part of the reactor as compared to the amount of oxygen supplied to the upstream end part.
