Embodiment 1

[0471] An embodiment of the present invention provides a waste FeOOH desulfurizer, wherein, based on the total mass of the FeOOH desulfurizer, the content of amorphous iron oxyhydroxide in the FeOOH desulfurizer is 60%, and the content of the carrier diatomite is The content of binder cellulose powder is 10%.

[0472] The above-mentioned catalyst is used as the desulfurization process of coal pyrolysis gas, which is summarized as follows:

[0473] (1) The compressed coal pyrolysis gas is cooled to 30-35°C, mixed with the air from the air pump, and enters the rough desulfurization tower. The process of entering from the bottom and exiting from the top is adopted to avoid liquid water entering the desulfurizer bed. Here only crude hydrogen sulfide removal and part of R-SH and thiophene removal are carried out.

[0474] (2) The gas after rough desulfurization is heated to 110-125°C for hydrolysis, and most of COS and CS2 are hydrolyzed into H2S.

[0475] (3) The temperature of ...

Embodiment 2

[0478] An embodiment of the present invention provides a waste FeOOH desulfurizer, wherein, based on the total mass of the FeOOH desulfurizer, the content of amorphous iron oxyhydroxide in the FeOOH desulfurizer is 80%, and the content of the carrier aluminum oxide is The content is 15%, and the content of the binder scallop powder is 5%. The desulfurization process of gas field water by the above-mentioned catalyst is as follows:

[0479] The above catalyst is loaded in a fixed bed reactor, and the gas field water containing H2S is fully contacted and reacted with it. The contact conditions are: temperature 35°C, pressure 0.2MPa and volume space velocity 10000h-1, the spent catalyst after desulfurization of gas field water The agent is the waste agent of FeOOH desulfurization agent of the present application.

Embodiment 3

[0481] An embodiment of the present invention provides a waste FeOOH desulfurizer, wherein, based on the total mass of the FeOOH desulfurizer, the content of γ-FeOOH in the FeOOH desulfurizer is 45%, and the content of α-FeOOH is 35%. , the content of the carrier molecular sieve is 15%, and the content of the binder scallop powder is 5%.

[0482] The above catalyst removes H from exhaust gas 2 The matrix process of S includes the following steps: 2 S content is 5500mg / cm 3 exhaust gas at 3000h -1 The space velocity is passed into the desulfurization section, and the desulfurization reaction is carried out at 30°C. In the outlet gas of the desulfurization section, H 2 When the content of S is less than or equal to 0.01ppm, the waste in the desulfurization section is collected and used as a catalyst for the liquefaction reaction of biomass.

Abstract

The invention discloses novel application of waste agents. The novel application involves the application of a FeOOH waste agent, a Fe21.333O32 waste agent, a ferric oxide waste agent and a Ni-Mo waste agent used as a hydro-liquefaction catalyst and a CO shift catalyst in an organic matter conversion process. The waste agents are used as idle resources, the price of the waste agents is farther lower than the price of fresh catalysts, so that the production cost is reduced, but a catalytic effect of the waste agents used as the hydro-liquefaction catalyst or the CO shift catalyst is comparableto a general catalyst effect.

Description

technical field [0001] The invention belongs to the field of catalyst application, and in particular relates to a new application of waste agent, in particular to the use of waste agent as a hydrogenation liquefaction catalyst, as a CO conversion catalyst, and in an organic matter conversion process. Background technique [0002] CO shift is a commonly used production process in industry, which uses the reaction of CO and water vapor to produce CO 2 and hydrogen. At present, this process has been widely used in the processing of hydrogen production, synthetic ammonia, synthetic methanol, methanation and synthetic oil, etc. The hydrogen-carbon ratio in the reaction system can be adjusted through CO conversion to meet the raw material requirements of the target product. [0003] In the CO shift reaction, the catalyst is an essential element in the reaction system. Common CO shift catalysts include high-temperature catalysts, medium-high-temperature catalysts and low-temperat...
