Method and system for acetylene (C2H2) or ethylene (C2H4) production

A method of converting at least one of fermentable and combustible organic wastes to produce acetylene or ethylene in a system including a closed loop, comprising:

• a) providing supplies of hydrogen, water, carbon monoxide, and carbon dioxide;
• b) providing a supply of methane;
• c) providing a catalyst system having firstly a catalyst selected from group VIII transition metal oxides, and secondly a catalyst support;
• d) treating said methane supply with said catalyst system for producing carbon;
• e) providing calcium oxide;
• f) reacting said carbon with said calcium oxide for producing an intermediate;
• and
• g) reacting said intermediate with water to produce acetylene, and optionally subjecting the produced acetylene to hydrogenation to produce ethylene;
• wherein:
• the supplies of hydrogen, water, carbon monoxide, carbon dioxide and methane are contributed from sources including the organic wastes;
• said intermediate is calcium carbide (CaC2);
• each of said methane supply and said carbon dioxide supply is derived from a combination of an external source and an internal source thereof yielded during said acetylene or ethylene production, said combination of said external and internal sources reacting during said acetylene or ethylene production to contribute to said supplies of hydrogen, water, carbon monoxide, carbon dioxide, and methane, for subsequent consumption in said acetylene or ethylene production;
• and
• said carbon dioxide passes through said closed loop.
