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

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, petrole...

Beschreibung
Zusammenfassung:	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, petroleum residual heavy fraction, or a mixture thereof. The nanocatalyst comprises a carbon nanomaterial in a concentration of between 99.99% and 80% by weight and at least one alkali metal in a concentration of between 0.01% and 20% by weight, based on the total weight of the nanocatalyst, and the specific surface area of the nanocatalyst varies between 400 and 1300 m2/g. Furthermore, the present invention also describes a process of gasification of 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 vapour, or a mixture thereof at a temperature that varies between 200 and 1300ºC; and obtaining a gaseous product comprising H2, CO, CO2, CH4.
