Process for hydrotreating an organic feedstock containing olefinic compounds and a
halogen component |
(57) Organic feedstocks (1) containing thermally unstable compounds and a halogen component
are treated by catalytic hydrogenation (2) in admixture with a gaseous recycle stream
(7) containing hydrogen and a hydrogen halide compound and, optionally, a recycle
stream (14) containing unreacted halogenated organic compounds. The resulting effluent
(3) is condensed (4) and separated (6) to produce said recycle stream (7) and a stream
(8) containing hydrogenated carbonaceous compounds. An anhydrous hydrogen halide product
(10) can be recovered. The stream (8) can be separated (9,12) to provide a product
stream (13) containing hydrogenated hydrocarbonaceous compounds and the optional recycle
stream (14) containing unreacted halogenated compounds.
