[0003] Production of carbon disulfide At present, most manufacturers in China use sulfur and methane (or natural gas) as raw materials to produce carbon disulfide. This method has good working conditions, high labor productivity, and equipment It has the characteristics of small footprint and high degree of automation, but at the same time, it has a large amount of hydrogen sulfide gas as a by-product. For every ton of carbon disulfide produced by the natural gas method, about 900 kg of hydrogen sulfide gas is produced at the same time, and a large amount of methane (or Natural gas), the current hydrogen sulfide recovery and utilization and the exhaust gas treatment after recovery have the disadvantages of high investment costs, high requirements for equipment materials, and large consumption of raw materials
