Embodiment 1

[0030] The raw materials used are: the hydrolysis residue of sawdust and the hydrolysis residue of rice husk respectively account for 50% (by weight).

[0031] The hydrolysis residue of cellulose waste with a particle size of less than 3mm enters the fluidized bed gasifier 1, and undergoes gasification reaction with the water vapor entering the fluidized bed gasifier 1. The gasification reaction temperature is 750°C, and the gasification Reaction pressure (gauge pressure) 30mmH 2 O, the cellulose waste hydrolysis residue add-on is 2.0kg / h; The quality of water vapor and the mass ratio (S / B) of cellulose waste hydrolysis residue are 1.5;

[0032] The residence time of water vapor in the fluidized bed is 3.0 seconds, and the residence time of cellulose waste hydrolysis residue in the fluidized bed reactor is 6.0 seconds;

[0033] The vaporized gas discharged from the top of the fluidized bed reactor 1 enters the atmospheric pressure fixed bed catalytic reactor 3 filled with cat...

Embodiment 2

[0040] Except the gasification reaction temperature, other process conditions were the same as in Example 1, the gasification reaction temperature was 850° C., and the hydrogen content (volume percentage) in the gas after the reaction reached 85.6%.

Embodiment 3

[0042] Except the catalytic reaction temperature, other process conditions are the same as in Example 2, the catalytic reaction temperature is 750° C., and the hydrogen content (volume percentage) in the crude gas after the reaction reaches 82.5%.

[0043] From the above results, it can be seen that hydrogen production by catalytic gasification of cellulose waste hydrolysis residue is a better hydrogen production method.

Abstract

The invention discloses a hydrogen preparing method of hydrolytic slag catalyzing gasification of cellulose waste, which is characterized by the following: adopting biological acid hydrolytic or enzyme hydrolytic waste as raw material; using catalyzing gasification method; preparing hydrogen-rich synthetic gas under fitful reacting temperature, pressure and time.

Description

technical field [0001] The invention relates to a method for preparing hydrogen, in particular to a method for preparing hydrogen by catalytic gasification of cellulose waste hydrolysis residue as a raw material. Background technique [0002] With the improvement of human living standards, people rely more and more on energy. However, due to the non-renewability of fossil fuels and their limited reserves, fossil energy has been increasingly exhausted, and the environmental crisis has become increasingly obvious. Today, seeking and developing new energy sources, especially renewable energy sources with little environmental pollution, has attracted global attention. [0003] Biomass usually refers to terrestrial plants (wood, fuelwood, straw, etc.) and aquatic plants. It is a stable renewable energy resource with abundant sources. my country is a large agricultural country, and a large amount of biomass waste is produced every year. The output of crop straw in my country alo...
