and Ru/C were used as catalysts during the gasification processes.The experimental results show that all the catalysts have good catalytic effect on the gasification of hemicellulose and for hydrogen production

in which Ru/C is the best one.Hydrogen production reaches 14.365 mol when added 0.8 g Ru/C to 1 kg hemicellulose

which is 1.6 and 1.9 times that when K

were added respectively.The hydrogen productivitywith the mixture of several catalysts mentioned above is greater than that with a single catalyst.Temperature increasing could obviously improve the productivity of hydrogen

and reduce methane production.In addition

different residence times affect the gasification

and 20 minutes is optimal.
