Problems solved by technology

However, due to its scarcity of resources, high price, and easy poisoning when dealing with chlorine-containing VOCs and sulfur-containing VOCs, it is only suitable for VOCs that do not contain chlorine or sulfur (Wu Wuling et al., Research Progress in Catalytic Combustion Catalysts, "Natural Gas Chemical Industry: C1 Chemistry and Chemical Industry, Issue 4, 2008)

Embodiment 1

[0038] The present invention is carried out with waste FH-UDS catalyst as raw material.

[0039] Take 1g of waste FH-UDS catalyst and place it in a crucible, and place it on a ten-thousandth electronic balance. After peeling, add water dropwise to it with a dropper. When the waste FH-UDS catalyst reaches a paste state, record the quality of the water added dropwise. This is the water required to impregnate 1 g of spent FH-UDS catalyst.

[0040] (1) Treatment of spent hydrogenation catalyst

[0041] First crush the spent FH-UDS catalyst to 60-100 mesh.

[0042] A. Catalysts with different CuO contents were prepared by equal volume impregnation method:

[0043] 1.5g organic waste gas catalytic combustion catalyst containing 1% CuO was prepared by impregnation method, the mass of spent FH-UDS catalyst was 1.485g, and the mass of CuO was 0.015g. Derivation shows that Cu(NO 3 ) 2 ·3H 2 The mass of O is 0.0453g, and the mass of water required is 0.8296g. Cu(NO 3 ) 2 ·3H 2 ...

Embodiment 2

[0063] The present invention is carried out with waste FF-20 catalyst as raw material.

[0064] Get 1g of spent FF-20 catalyst and place it in a crucible, and place it on a ten-thousandth electronic balance, drop water therein with a dropper after peeling, record the quality of dripping water when the spent FF-20 catalyst reaches a paste state, This is the water required to impregnate 1 g of spent FF-20 catalyst.

[0065] (1) Treatment of spent hydrogenation catalyst

[0066] First crush the spent FF-20 catalyst to 60-100 mesh.

[0067] Prepare the catalyst of different CuO content with equal volume impregnation method (the mode with embodiment 1)

[0068] Take 1g of spent FF-20 catalyst as an example, the mass of water used for complete wetting is 0.6g. Then calculate and prepare 2 g of organic waste gas catalytic combustion catalysts containing 1%, 3%, 5%, 7%, 10%, and 20% copper oxide respectively. The experimental results of this embodiment are similar to those of Embo...

Abstract

The invention relates to the technical field of petrochemical industry and provides a process for processing organic waste gas by utilizing a waste hydrogenation catalyst. The process comprises the following steps: crushing the waste hydrogenation catalyst into 60 to 100 meshes, dipping the crushed waste hydrogenation catalyst into a copper nitrate solution and roasting to prepare an organic waste gas catalytic combustion catalyst with copper oxide capacity of 1 to 20 weight percent; and heating the organic waste gas to 300 to 400 DEG C and performing catalytic combustion through the organic waste gas catalytic combustion catalyst. The process combines the actual emission characteristics of the waste catalyst and the volatile organic waste gas of the petrochemical industry enterprises, applies a large number of waste hydrogenation catalyst of the petrochemical industry enterprises to catalytic combustion reaction of the volatile organic waste gas, provides a new solution way for purification of the volatile organic waste gas, effectively solves the environmental pollution problem caused by the emission of the volatile organic waste gas, forms a resource recovery-pollutant deep purification integrated technology and process, and has low processing cost, good effect and important social benefits and industrial application background.

Description

technical field [0001] The invention relates to the field of petrochemical technology, in particular to a process for treating organic waste gas with a waste hydrogenation catalyst. Background technique [0002] Catalysts are also needed in the petroleum refining process and the control and treatment of environmental pollutants. According to statistics, the world consumes about 800,000 tons of catalysts every year, of which about 415,000 tons (accounting for 52%) are refining catalysts. The short catalyst life is only a few months or even a few days, and the long one can reach seven or eight years. Large quantities of spent catalysts are produced annually in chemical production. Most of these catalysts lose their activity partially or completely due to the thermal aging of the catalyst or the poisoning of certain poisons; the activity is also reduced because some pollutants such as oil, coke, etc. accumulate on the active surface of the catalyst or block the pores of the c...
