  • Patent number: 4693873
    Abstract: A process for scrubbing a synthesis gas stream containing residual amounts of iron containing particulate solids and minor amounts of HCN is disclosed, the process being characterized by scrubbing of the synthesis gas with an aqueous reactant solution, and providing for conversion of any iron complex or iron complexes formed during scrubbing by a low temperature conversion step.
    Type: Grant
    Filed: December 30, 1985
    Date of Patent: September 15, 1987
    Assignee: Shell Oil Company
    Inventor: Daniel C. Baker
  • Patent number: 4654148
    Abstract: A process for removal of iron cyanide complex or complexes from a solution is described, the process being characterized by contact of the solution containing the complex or complexes with ammonium polysulfide or sodium polysulfide, or a mixture thereof, at a temperature of from about 110.degree. C. to about 180.degree. C.
    Type: Grant
    Filed: December 30, 1985

    Assignee: Shell Oil Company
    Inventor: Daniel C. Baker
  • Patent number: 4624837
    Abstract: A process for the removal of cyanide complex or complexes from synthesis gas streams also containing residual iron containing particulate matter is disclosed, the process being characterized by scrubbing of the synthesis gas stream with water or an aqueous stream, removal of absorbed HCN, if any, from solution used in scrubbing, and contact of substantially HCN-free scrubbing solution with a polysulfide reactant at temperatures of from 110.degree. C. to 180.degree. C.
    Type: Grant
    Filed: December 30, 1985
