ABSTRACT:
This invention is a process for removing minor amounts of organic halide e.g., organic chloride, contaminants from hydrocarbon feedstocks by contact with a regenerable solid adsorbent comprising a metal and/or metal hydride selected from nickel, cobalt or iron, or mixtures thereof on a porous refractory support, such as silica, whereby the halide present in the hydrocarbon feedstock is converted substantially to an insoluble metal halide salt of the supported metal or metal hydride with the hydrocarbon feedstock being recovered from the contacting step substantially free of organic halide contaminant. Also disclosed is a process for regeneration of the adsorbent loaded with metal halide from the hydrocarbon feedstock contacting step and an integrated process where the regenerated adsorbent is reused to remove additional organic halide from the hydrocarbon feedstock.
