Abstract
The present invention is directed towards a process of preparing a catalyzed carbonaceous material and preventing polymerization of cracked volatile products during pyrolysis or gasification of carbonaceous materials.
Claims5
A process of preparing a catalyzed carbonaceous material, said process comprising the steps:
- (a) soaking a carbonaceous material in a soluble metal salt solution,
- (b) drying the carbonaceous material of step (a),
- (c) raising the temperature of the carbonaceous material to a temperature sufficient to decompose the metal salt to its oxide and/or carbonates to obtain a catalyzed carbonaceous material,
- wherein the soluble salt is capable of decomposing into oxide and/or carbonates at a temperature which is below the decomposing temperature of the carbonaceous materials, and wherein the carbonaceous material is a lignocellulosic biomass.
