PRODUCTION OF CARBON FIBER FROM ASPHALTENES
20230357026 · 2023-11-09 · ·

There is provided a process and system for producing carbon fiber products. The process can involve deasphalting a heavy hydrocarbon feedstock, which can contain native asphaltenes, to produce a solid asphaltene particulate material, which can be further treated to produce the carbon fiber products. In some implementations, the solid asphaltene particulate material can be extruded in the presence of a polymer. In some implementations, the solid asphaltene particulate material can be chemically treated with a chemical agent including a Lewis acid, an oxidizing agent and/or a reducing agent before extrusion. In some implementations, the process can further produce activated carbon fibers.

CONTINUOUS CARBONACEOUS MATTER THERMOLYSIS AND PRESSURIZED CHAR ACTIVATION WITH HYDROGEN PRODUCTION
20230382740 · 2023-11-30 ·

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.
