Process for gasification of a carbonaceous raw material of low value as a fuel using a nanocatalyst

Abstract

The present invention describes a mixture comprising carbonaceous raw material of low value as a fuel and a nanocatalyst. The catalytic mixture comprises from 1% to 50% by weight of a nanocatalyst; and from 99% to 50% by weight of carbonaceous raw material selected from petroleum coke, coal, heavy residual fraction of oil, or a mixture thereof. The nanocatalyst comprises a carbon nanomaterial of between 99.99% and 80% by weight in contents and at least one alkali metal of between 0.01% and 20% by weight in contents, based on the total weight of the nanocatalyst, and the specific surface area of the nanocatalyst ranges between 400 and 1300 m2/g. Furthermore, the present invention also describes a process for gasifying the catalytic mixture which comprises the steps of placing the mixture in a gasifier; heating the mixture in the presence of an oxidizing agent selected from air, pure oxygen, carbon dioxide, water vapor, or a mixture thereof at a temperature ranging between 200 and 1,300° C.; and obtaining a gaseous product comprising H2, CO, CO2, CH4.
