Abstract
We provide a catalytic process to reduce an organic halide in a hydrocarbon, comprising: a. producing the hydrocarbon comprising the organic halide in a process unit; and b. contacting the hydrocarbon comprising the organic halide with a metal chloride under anhydrous conditions in a halide removal vessel to produce a contacted hydrocarbon having from 50-100 wt % of a total halide in the hydrocarbon removed. We also provide an apparatus for performing this process.
Claims26
A catalytic process to reduce a content of an organic chloride in a stream comprising a hydrocarbon and an organic chloride, comprising:
- a) producing the stream comprising the hydrocarbon and the organic chloride in a process unit;
- and
- b) contacting the stream comprising the hydrocarbon and the organic chloride with both a metal chloride catalyst and a metal oxide in a halide removal vessel under anhydrous conditions at a temperature of from 50° C. to less than 225° C. to decompose the organic chloride and produce an effluent comprising HCI gas and a contacted saturated hydrocarbon that is a gasoline blending component, a middle distillate, or a base oil, wherein:
- the metal oxide absorbs the HCI gas;
- the stream comprising the hydrocarbon and the organic chloride has a total chloride content and the contacted saturated hydrocarbon has a lower total chloride content that is less than the total chloride content by 50 to 100 wt %;
- and
- the contacting with the metal chloride does not comprise absorption or adsorption of the organic chloride.
