A new green method for purifying acetylene with the help of Zeolite molecular sieve

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)


2- Arsine,


3- Hydrogen sulfide, (Maximum concentration must be 100 ppm)


4- Ammonia


5- water.


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.




With respect to "What is your suggestion?", I note that apparently hydrogen peroxide does not readily react with acetylene, [see comments here](https://patents.google.com/patent/CN103693622A/en), for example, to quote:



> 
> A hydrogen peroxide (H2O2) solution reacts with calcium carbide (CaC2), so as to generate the mixed gas of oxygen (O2) and acetylene (C2H2).

However, the created mix of acetylene and hydrogen peroxide appears per a recent 2018 work to present an enhanced explosion hazard (see ["Water Vapor and Hydrogen Peroxide as Promoters of Acetylene Explosive Decay"](https://link.springer.com/article/10.1134/S19907931180402310)), where "the acetylene explosiveness is largely determined by humidity" implying the further employment of a drying agent.


Also, on phosphine with hydrogen peroxide, to quote [a source](https://pubag.nal.usda.gov/catalog/666980):



> 
> Reactive oxygen species for lipid peroxidation may therefore be derived from direct reaction of PH3 with H2O2 as an alternative hypothesis to their respiration-linked formation.

Also, $\ce{H2S}$ and $\ce{AsH3}$ both react with $\ce{H2O2}$ see, for example, ["Catalyzed oxidation of arsenic(III) by hydrogen peroxide on the surface of ferrihydrite: an in situ ATR FTIR study"](https://pubmed.ncbi.nlm.nih.gov/12666928/).


As such, I would suggest a possible hydrogen peroxide scrubbing step, per the manner described in the literature, as a feasible green but apparently, not completely safe, route.
