Abstract

The invention discloses a movable coal synthesis gas metnanation catalyst testing platform and a testing method. The testing platform comprises a gas component conversion and purification part and a gas methanation part which can be transported in a container, wherein the gas component conversion and purification part comprises a sulfur water resistant coal gas conversion device, a moderate temperature zinc oxide desulfurization device, a gas-water separation device, and an NaOH and 5A molecular sieve column decarbonization device; and the gas methanation part is a three-section methanation reactor device. The testing method comprises the steps that 1, the sulfur water resistant coal gas conversion device converts a ratio of hydrogen to carbon monoxide in coal gas into an appropriate value; 2, the moderate temperature zinc oxide desulfurization device reduces sulfur content to below 0.2ppm; 3, the gas-water separation device separates water in the coal gas; 4, the NaOH and 5A molecular sieve column decarbonization device performs decarbonization to enable the content of carbon to be below 20 ppm; and 5, the three-section methanation reactor device performs coal gas methanation reaction. The platform is used for testing an optimal methanation reaction condition of various gas source conditions, adapts to testing of different virgin gas components, different operation conditions and different catalysts, and can test and evaluate a methanation technology, an operation parameter and catalyst performance.

Description

technical field [0001] The invention relates to the technical field of coal-to-natural gas, in particular to a movable coal-to-synthesis gas methanation catalyst test platform and a test method. Background technique [0002] my country's energy structure is "more coal, less oil, and gas", with insufficient oil and gas resources and relatively rich coal resources. During the combustion of coal, a large amount of sulfur oxides, nitrogen oxides, and dust pollution are emitted, which can cause acid rain, photochemical smog and other weather pollution. Dust, especially PM2.5, can cause human respiratory diseases. my country is in the mid-to-late stage of industrialization, and the energy demand is huge, and the discharge of pollutants is also intensified, resulting in frequent environmental incidents. Therefore, we must pay attention to environmental protection, promote energy conservation and emission reduction, and convert coal efficiently and cleanly to meet the requirements ...
