Feedstock Conversion To Fuel On High Pressure Circulating Fluidized Bed

摘要

There is provided a process and systems for producing fuels via pyrolysis of carbonaceous feedstock under pressure and temperature in an efficient manner using a circulating fluidized bed with catalyst(s). The pressure and temperature are selected to provoke supercritical conditions, and pyrolysis, hydropyrolysis, hydrotreating, and optionally reforming treatment of the carbonaceous feedstock is carried out simultaneously in one reactor on a recirculating fluidized bed containing catalysts.

1. A process for the production of fuel comprising,
(a) providing in a reaction vessel a carbonaceous feedstock, a lift gas mixture of inert gas components, hydrogen, a fluidized bed of inert particulate solids and a hydrogenation catalyst; (b) pyrolyzing the carbonaceous feedstock to form fuel product components under temperature and pressure so as to establish supercritical conditions of temperature and pressure of at least one component of the carbonaceous feedstock, lift gas, hydrogen, water or fuel product;
wherein the pyrolyzing comprises simultaneous pyrolysis, hydropyrolysis and hydrotreating of the carbonaceous feedstock to form said fuel.
