Hydrocarbon-containing mixture and method and system for making the same

A method for producing a hydrocarbon-containing mixture, comprising:

• providing a feed stream comprising acetylene;
• and
• reacting said feed stream with solid calcium carbide (CaC2) to produce a hydrocarbon-containing mixture comprising acetylene and butenyne, wherein said hydrocarbon-containing mixture (i) further comprises dimethyl butadiyne, (ii) comprises at least 10% butenyne, or (iii) both.

A system for producing a hydrocarbon-containing mixture, comprising

• an acetylene production subsystem comprising at least one vessel and an acetylene feed pipe for delivering acetylene to a diffuser,
• wherein the finishing vessel is in fluid communication with the diffuser, which is also in fluid communication with the acetylene feed pipe, wherein gas exiting the diffuser passes through a reaction chamber filled with solid calcium carbide then passes through a finishing vessel outlet.
