APPARATUS, SYSTEM, AND METHOD FOR SHALE PYROLYSIS
20210395613 · 2021-12-23 ·

Apparatuses, systems, and methods are disclosed for shale pyrolysis. A retort may include a first side and a second side opposite the first side, where the first side and the second side include descending angled surfaces at alternating angles to produce zig-zag motion of shale descending through the retort. Steam distributors may be coupled to the first side, with collectors coupled to the second side, to produce crossflow of steam and heat across the descending shale. A steam temperature control subsystem may be coupled to the steam distributors and may deliver higher-temperature steam to an upper portion of the retort and lower-temperature steam to a lower portion of the retort.

Process to prepare a char product and a syngas mixture

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.
