Abstract
Official abstract text for this publication.
Processes for the production of alkenes are provided. The processes make use of methane as a low cost starting material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for the production of one or more alkenes and/or aromatic compounds, comprising reacting a feedstream comprising methane with at least one monochloroalkene having the formula R 1 —CCl═CH—R 2 , where R 1 and R 2 may each independently be hydrogen or an alkyl group having from 1 to 4 carbon atoms, in the presence of a free radical initiator at a temperature of less than 700° C. and a pressure of less than 4000 psig. 2. The process of claim 1 , where the monochloroalkene comprises vinyl chloride. 3. The process of claim 2 , wherein the vinyl chloride is generated by reacting acetylene and HCl, wherein the HCl is generated by the process. 4. The process of claim 1 , wherein the free radical initiator comprises carbon tetrachloride, hexachloroacetone, hexachloroethane, or combinations of these. 5. The process of claim 1 , wherein the one or more alkenes comprise from three to 10 carbon atoms and/or the one or more aromatic compounds comprise from 5 to 10 carbon atoms. 6. The process of claim 5 , wherein the one or more alkenes comprise propene and/or 1,4-pentadiene. 7. The process of claim 6 , further comprising converting at least one of the one or more alkenes to one or more alkanes. 8. The process of claim 1 , wherein at least a portion of the monochloroalkene is generated within, or upstream of, the process. 9. The process of claim 1 , wherein the process produces one or more monochloroalkanes comprising from three to 10 carbon atoms.
