Abstract
A process for selectively producing ethyl mercaptan from a reactant mixture such as, for example, refinery fuel gas mixture is provided which comprises contacting, in the presence of a catalyst such as, for example, oxides of cobalt and molybdenum supported on aluminum, the reactant mixture with hydrogen sulfide wherein the reactant mixture contains ethylene and at least one other olefin such as, for example, propylene. The reactant mixture can also contain other components such as, for example, hydrogen, ethane, methane, propylene, or propane, or mixtures thereof.
Claims15
A process for selective production of ethyl mercaptan from a reactant mixture which comprises hydrogen, ethylene and propylene comprising contacting, in the presence of a catalyst, said mixture with hydrogen sulfide at a temperature in the range of from about 225.degree. C. to about 275.degree. C. under a pressure in the range of from about 50 psig to about 450 psig for a period sufficient to produce said ethyl mercaptan.
A process for selective production of ethyl mercaptan from a fuel gas mixture comprising contacting said fuel gas mixture, in the presence of oxides of cobalt and molybdenum, with hydrogen sulfide;
- wherein said fuel gas mixture comprises hydrogen, methane, ethylene, ethane, propylene, and propane;
- said oxides are supported on alumina;
- and said fuel gas mixture has a feed rate in the range of from 0.2 to 0.3 liter of said fuel gas mixture per gram of said catalyst per hour.
