Embodiment 1

[0038] Such as figure 1 As shown, a converter gas purification treatment method of the present embodiment comprises the following steps:

[0039] S1. Use activated carbon to remove impurities in the gas;

[0040] S2. Using the sulfided molybdenum series multi-component catalyst to remove oxygen and cyanide in the gas.

Embodiment 2

[0042] This embodiment is a definition optimized on the basis of the above-mentioned embodiment 1, such as figure 1 As shown, a converter gas purification treatment method of the present embodiment comprises the following steps:

[0043] S1. Use activated carbon to remove impurities in the gas;

[0044] S2. Using the sulfided molybdenum series multi-component catalyst to remove oxygen and cyanide in the gas.

[0045] Further, the molybdenum-based multi-component catalyst in the sulfided state is NSTO-1 sulfur resistant deoxidizer.

[0046] In the process of producing ethanol by biological fermentation of converter gas, the gas needs to be purified to remove most of the oxygen and cyanide harmful to fermenting organisms in the gas. Processing method of the present invention is divided into following two parts:

[0047] First, considering that the gas may contain tar, naphthalene, dust and other impurities that are harmful to the catalyst, a protective tank is installed at th...

Abstract

The invention belongs to the technical field of converter gas treatment methods, and discloses a converter gas purification treatment method. According to the method, impurities such as tar, naphthalene and dust in the raw material gas are removed by utilizing the adsorption effect of the activated carbon, and the effect of protecting a subsequent catalyst can be achieved while the impurities areremoved. And then oxygen and cyanide in the coal gas are removed by using a sulfurized molybdenum-based multi-element catalyst, so that the coal gas is fully purified, and subsequent production is facilitated. The activity of the catalyst is kept by adding carbon disulfide, so that the reaction is more efficient, and the purification effect is improved. The treatment method disclosed by the invention is simple to operate, has a good purification effect on the coal gas, and is beneficial to production of ethanol through biological fermentation of the converter coal gas.

Description

technical field [0001] The invention belongs to the technical field of converter gas treatment methods, and in particular relates to a converter gas purification method. Background technique [0002] The total amount of energy resources in my country is relatively rich, but due to the large population base, the per capita energy resource possession is at a relatively low level in the world, especially the per capita oil and natural gas resources are only less than 10% of the world average level. With the steady and rapid development of the national economy and the upgrading of the consumption structure of urban and rural residents, energy consumption will continue to maintain a growth trend, and the contradiction of resource constraints will become more prominent. Therefore, it is imperative to find and develop new energy sources to replace crude oil as soon as possible, and it is an urgent need for China's energy security. Fuel ethanol and biodiesel can replace gasoline an...
