Abstract
A method is provided for electro-gasification of pet-coke, including the steps of providing a pet-coke material; treating the pet-coke material to obtain a treated pet-coke material having an average particle size of between about 20 and about 106 μm; and exposing the treated pet-coke material to electro-gasification conditions to produce synthesis gas and/or hydrogen. Extraction of metals from the pet-coke is facilitated.
Claims9
A method for electro-gasification of pet-coke, comprising the steps of:
- providing a pet-coke material;
- treating the pet-coke material to obtain a treated pet-coke material having an average particle size of between about 20 and about 106 μm, wherein the treating step comprises exposing the pet-coke material to a temperature of between about 250° C. and about 450° C. for a period of time effective to provide a thermally treated pet-coke, and then milling the thermally treated pet-coke to obtain the treated pet-coke, wherein the treated pet-coke material has increased porosity and reactivity as compared to starting pet-coke material;
- and
- exposing the treated pet-coke material to electro-gasification conditions to produce synthesis gas and/or hydrogen.
