[0002] Acetylene is a colorless, odorous, highly flammable gas that is widely used in industry, mainly for lighting, welding, and rubber synthesis. Acetylene purification is an important part of the acetylene production process, and its purpose is to remove impurities in acetylene gas, such as hydrogen sulfide and phosphine, to improve the purity and quality of acetylene. These impurities not only affect the subsequent use of acetylene, but may also pose a threat to production equipment and personal safety.
