I'm investigating for a green method for purification of acetylene in order to reduce the environmental impacts in manufacturing plants. In the current method mercuric chloride is used in the purification material that is indeed harmful to the environment. The main impurities consists of:
1- Phosphine (Maximum concentration must be 200 ppm)
3- Hydrogen sulfide, (Maximum concentration must be 100 ppm)
Recently, I read that Zeolite molecular sieves are used to purify many gases in industry. Further information can be found in the article below:
If I noticed correctly, this porous material absorbed different gases with respect to its amount of pore diameter. Gases that their molecular sizes are similar or smaller than the pore diameter will be absorbed while other gases will pass from this material. I wonder that if we could use this material for purifying acetylene. Since the size of the gas molecules in the acetylene gas mixture are different, this seems practical.
What is your suggestion?
Do you think that Zeolite molecular sieves can be a solution for purifying acetylene? Do you know any papers or articles that is relevant to this subject?
Thank you very much.
