Abstract
An electrogenerative cell and a process for the oxidation or halogenation of hydrocarbons is disclosed wherein a cell body containing a permselective membrane which divides said cell body into anolyte and catholyte compartments containing a liquid electrolyte consisting repectively of anolyte and catholyte and a porous anode and a porous cathode. Anolyte and catholyte compartments are fed respectively with a mixture of a liquid electrolyte and an unsaturated hydrocarbon and a mixture of a liquid electrolyte and a halogen or oxygen, wherein said electrolytes are fed to said cell at ambient or elevated temperature and pressure. A halogenated or oxygenated hydrocarbon is recovered and electrolytes, unsaturated hydrocarbon, halogen or oxygen are recycled to the cell.
Claims11
A process for producing electric power by the electrogenerative halogenation or oxidation of at least one unsaturated hydrocarbon in an electrochemical cell having an anode and cathode separated by a permselective membrane or electrolyte permeable diaphragm comprising:
- (A) flowing a first liquid electrolyte and said unsaturated hydrocarbon to an anolyte compartment of said cell containing a porous anode;
- (B) flowing a second liquid electrolyte and a halogen or oxygen gas to a catholyte compartment of said cell containing a porous cathode;
- (C) reacting said unsaturated hydrocarbon with said halogen or said oxygen at ambient or elevated temperatures and pressures;
- (D) recovering a halogenated or oxygenated hydrocarbon;
- (E) recycling said electrolytes, unsaturated hydrocarbon, and halogen or oxygen gas to said cell.
An electrochemical cell consisting of:
- (A) A cell body,
- (B) A porous anode in electrical contact with a current collector all in an anode compartment,
- (C) A porous cathode in electrical contact with a current collector all in a cathode compartment,
- (D) An anion permeable permselective membrane separating B and C,
- (E) Feeding and exiting means for passing a mixture of a first electrolyte and at least one unsaturated hydrocarbon through said anode compartment, and
