Embodiment 1~11

[0029] The raw biomass synthesis gas provided by the present invention is prepared through the following steps.

[0030] (1) Prepare and obtain crude synthesis gas:

[0031] Using corncobs as raw materials and circulating fluidized bed gasifier as the production equipment, the crude synthesis gas is prepared as follows: fill 10Kg of corncobs in the circulating fluidized bed gasifier, gasification agent (i.e. Air) is blown upward from the bottom into the gasification furnace by the blower, so that the combustion and gasification reaction of the corncob raw material is in a boiling state. The gasification temperature is 750°C, the air equivalent ratio is 0.21, and the gas yield is 1.8m 3 / kg, the gasification yield is 70%;

[0032] The volume ratio of the prepared crude synthesis gas component is: H 2 16.19%, CO 12.34%, C 2 h 4 2.5%, CO 2 21.90%, CH 4 14.92%, N 2 32.15%;

[0033] H in the prepared crude synthesis gas 2 The ratio of / CO=1.312.

Abstract

The invention belongs to the technical field of biomass energy synthesis and particularly relates to a method for reforming biomass crude syngas by taking hydrogen peroxide as a raw material. The method comprises steps as follows: a catalyst with metal oxides such as NiO, Mo2O5, CeO2, ZrO2, RuO2 or PdO supported on ZSM-5 molecular sieves or cordierite is prepared, hydrogen peroxide is taken as the raw material, the biomass crude syngas is reformed at 200-450 DEG C, and the like. According to the method, hydrogen peroxide is taken as the raw material for reforming the ratio of H2 / CO in the biomass crude syngas, and meanwhile, the ratio of H2 in the crude syngas is better increased through optimization of the catalyst and the reaction temperature, so that the biomass crude syngas is more suitable for preparation of lower-alcohol fuel. Hydrogen peroxide adopted in the method is easy to obtain, lower in cost and higher in safety; the prepared crude syngas is more suitable for preparation of the lower-alcohol fuel, so that the method has greater practical significance in promoting biomass energy utilization and conversion and popularizing new energy.

Description

technical field [0001] The invention belongs to the technical field of biomass energy synthesis, and in particular relates to a method for reforming crude biomass synthesis gas by using hydrogen peroxide as a raw material. Background technique [0002] With the depletion of fossil energy and the increasingly serious environmental problems such as smog caused by the use of fossil energy, people are doing more and more research on alternative energy sources for fossil energy. At the same time, in recent years, with the air pollution caused by straw burning, it has seriously affected people's clothing, food, housing and transportation, and even endangered human health. People's desire for the transformation and utilization of straw has become stronger and stronger. On the other hand, the biomass energy contained in straw has the characteristics of abundant resources, high combustion calorific value, and wide application range, so it is an ideal new energy source. [0003] In t...
