You must have the gas in contact with a Lindlar's Catalyst.
Lindlar's Catayst produces a cis-alkene.

A Lindlar's Catalyst is a Palladium that is poisoned with lead and CaCo3
Palladium usually turns an alkyne into an alkane.
But the Lindlar's catalyst can contaminate your sample with poisonous lead.

That is probably the easiest & inexpensive way to make a cis-alkene.
cis-alkenes are very hard to produce and needed a contact catalyst.
You may as well find a replacement for a Lindlar's Catalyst.
There are some ChemLab suppliers that claim to have a better alternative for the Lindlar's Catalyst.
