Abstract
The present invention provides a process for producing hydrogen iodide. The process includes providing a vapor-phase reactant stream comprising hydrogen and iodine and reacting the reactant stream in the presence of a catalyst to produce a product stream comprising hydrogen iodide. The catalyst includes at least one selected from the group of nickel, cobalt, iron, nickel oxide, cobalt oxide, and iron oxide. The catalyst is supported on a support.
Claims14
A process for producing hydrogen iodide, the process comprising:
- providing a vapor-phase reactant stream comprising hydrogen and iodine;
- reacting the reactant stream in the presence of a catalyst to produce a product stream comprising hydrogen iodide (HI), unreacted iodine (12) and unreacted hydrogen (H2);
- separating unreacted iodine,
- condensing a stream comprising hydrogen iodide (HI);
- and
- optionally venting or recycling a stream comprising unreacted hydrogen (H2).
