Embodiment Construction

[0013] 13%Ni-6%Ce-2%Mn / γ-Al 2 o 3 (wt.) Catalyst preparation: prepared by step-by-step impregnation method, that is, first impregnating additives Ce and Mn, and then impregnating active component Ni. The calcination process adopts step-by-step calcination, that is, calcination at 823K for 2 hours, and then calcination at 1023K for 5 hours ;

[0014] The method of producing syngas: paper mill sewage is treated with microbial anaerobic treatment to produce biogas (CH 4 65.10%, CO 2 30.20%, CO 0.85%, H 2 2.01%, H 2 S 0.15%, O 2 0.17%, N 2 1.2%, C m h n 0.15%), after wet tannin desulfurization, the H in the gas 2 S content reduced to 0.05g / Nm 3 Next, the desulfurized gas and air are mixed into the reformer at a volume ratio of 2:1, and the methane undergoes a partial oxidation reaction. At the same time, the gas is heated to 973-1073K and enters the reforming reactor. %Mn / γ-Al 2 o 3 (wt.) Under the action of catalyst, methane-CO 2 reforming reaction to produce ...

Abstract

The present invention relates to the efficient clean utilization of marsh gas and is especially one new kind of catalyst for reforming methane-CO2 to produce synthetic gas. The present invention is one green process to utilize marsh gas with methane and CO2 as main components to produce synthetic gas via reformation. The present invention is significant for sustained supply of power source and environment protection.

Description

Technical field: [0001] The invention relates to a new method for high-efficiency and clean utilization of biogas, and further relates to a new catalyst for methane-CO2 reforming to produce synthesis gas. Background technique: [0002] Due to the limited resources of fossil energy such as oil, coal and natural gas, a large amount of exploitation and use will inevitably lead to the depletion of conventional energy in the future, and the production of fuel from syngas has attracted increasing attention. Biogas engineering technology is a very effective technology for controlling organic waste pollution and developing renewable energy. At present, more than 1,000 large and medium-sized biogas projects have been built in the country, and the total volume of anaerobic digestion units is 700,000 cubic meters. The national biogas production potential is far greater than the current level. Under the guidance of the national environmental protection policy, its potential will be grad...
