Problems solved by technology

However, the pressure in the raw material gas produced by this technology is high (3.8MPa) and the water-gas ratio is large (water / gas is about 1.1), and there is no organic gas under high water / gas and high pressure process conditions at home and abroad. It is a precedent for the industrial operation of sulfur conversion. Therefore, it is very important to carry out the development and research of new processes for organic sulfur conversion of high water / gas high pressure feed gas

Description

technical field [0001] The present invention relates to a new process for organic sulfur conversion of high-pressure, high-water / gas, sulfur-containing raw material gas, especially a new process for the production of organic sulfur conversion with high-water / gas, high-pressure, high-CO, sulfur-containing raw material gas, and specifically relates to a A new process for the conversion of organic sulfur by using coal as raw material gasification to produce ammonia synthesis gas, oxo synthesis gas and city gas. Background technique [0002] my country is rich in coal resources, and using coal as raw material to produce ammonia, methanol, coal-to-oil and coal-to-gas occupies a very important position in my country's chemical industry. However, the raw material gas produced from coal contains a small amount of organic sulfur such as COS and CS2 that are difficult to remove, and it is usually removed by converting it into inorganic sulfur. [0003] At present, there are three ind...
