Abstract
A method of synthesizing hydrocarbons from smaller hydrocarbons includes the steps of hydrocarbon halogenation, simultaneous oligomerization and hydrogen halide neutralization, and product recovery, with a metal-oxygen cataloreactant used to facilitate carbon-carbon coupling. Treatment with air or oxygen liberates halogen and regenerates the cataloreactant.
Claims20
A method of making a product hydrocarbon having a carbon number Cn, where n≧2, comprising:
- reacting a halogenating agent with a reactant hydrocarbon having a carbon number Cm, where m<n, to form a halogenated hydrocarbon;
- contacting the halogenated hydrocarbon with a metal-oxygen cataloreactant to form hydrogen halide and a plurality of product hydrocarbons, wherein at least a portion of the product hydrocarbons have a carbon number Cn, where n≧2, and wherein at least 50% of the product hydrocarbons are C6 or higher hydrocarbons or at least 70% of the product hydrocarbons are C5 or higher hydrocarbons;
- trapping halogen from the hydrogen halide with the metal-oxygen cataloreactant;
- recovering the product hydrocarbons;
- and
- regenerating the metal-oxygen cataloreactant to recover the halogen.
