Continuous carbonaceous matter thermolysis and pressurized char activation with hydrogen production
11834338 · 2023-12-05 ·

Continuous thermolysis of carbonaceous matter in a controlled temperature and steam environment to produce a low volatility char, with subsequent steam activation of the char under pressure producing activated carbon and pressurized syn-gas, all of which are carried out in a reactor system including one or more vessels. The syn-gas is enriched in hydrogen in a high temperature shift reactor and separated in a pressurized swing adsorber to provide a pressurized pure hydrogen stream and a low-pressure combustible tail gas. The tail gas and the volatiles from the thermolysis step are combusted to provide process steam and electric power. The electric power is used to supplement the thermal requirements of the process with the balance being exported.

Treatment of spent cannabis biomass with activating agent
20210171354 · 2021-06-10 ·

A process to transform spent cannabis biomass into activated carbon via a treatment involving a chemical activation process. The spent cannabis biomass is mixed with an activating agent and then subjected to a heat treatment. The spent cannabis biomass is heated in stages, the first to remove water and volatile components, and the second to reclaim leftover cannabinoids. During a third, higher temperature stage, the biomass is converted to activated carbon.
