Abstract
A method of producing benzene on a high yield basis is disclosed in which non-hdyrocarbon carbonaceous raw materials are reacted with an alkali metal or an alkaline earth metal in the form of molten metal, metallic hydroxide or metallic oxide to produce the metallic carbide; the metallic carbide is hydrolyzed to produce acetylene; and the acetylene is cyclized to benzene. Side reactions are controlled to maximize yields. Benzene may be used to extend gasoline.
Claims10
The process of producing benzene comprising:
- a. reacting non-hydrocarbon carbonaceous material in a sealed, substantially leak-free reactor with lithium in the form of lithium metal, lithium hydroxide or lithium oxide at a temperature of at least 500.degree. C in the strict absence of air and moisture to produce lithium carbide;
- b. hydrolyzing said lithium carbide to produce acetylene and lithium in at least one of said forms;
- c. cyclizing said acetylene to produce benzene;
- d. and recycling through step (a) said lithium produced in step (b).
