  • Patent number: 5744669
    Abstract: A process for the conversion of a halogenated organic stream containing trace quantities of organic nitrates to produce a stream comprising hydrogenated hydrocarbonaceous compounds free from organic nitrates and halogenated organic compounds by means of contacting the feed stream and hydrogen with a selective hydrogenation catalyst in a first hydrogenation zone at hydrogenation conditions to convert the organic nitrates into water-soluble nitrogen compounds while effectively minimizing the production of hydrogen halide compounds. The resulting effluent from the first hydrogenation zone is contacted with an aqueous scrubbing solution to recover at least a portion of the water-soluble nitrogen compounds in order to produce a stream containing halogenated organic compounds and essentially free of nitrogen compounds which is then introduced into a second hydrogenation zone operated at selected hydrogenation conditions to produce water-soluble hydrogen halide compounds and hydrogenated hydrocarbonaceous compounds.

  • Patent number: 5600041
    Abstract: A process for treating a stream containing halogenated organic compounds and having trace quantities of organic nitrates to produce a stream comprising halogenated organic compounds free from organic nitrates by the utilization of a hydrogenation zone operated at selective hydrogenation conditions in order to convert the organic nitrates to water-soluble nitrogen compounds while minimizing the production of hydrogen halide compounds. The resulting water-soluble nitrogen compounds are removed by extraction with an aqueous stream.

  • Patent number: 5354931
    Abstract: The invention provides a process for hydrotreating an organic feedstock containing oxygen compounds and a halogen component by means of removing the oxygen compounds with an adsorbent and then contacting the resulting organic feedstock having a reduced concentration of oxygen compounds and a gaseous recycle stream containing hydrogen with a hydrogenation catalyst in a hydrogenation reaction zone to produce an anhydrous liquid stream comprising hydrogenated hydrocarbonaceous compounds having a reduced concentration of halogen and a hydrogen halide compound. The resulting effluent from the hydrogenation zone is optionally separated to produce a hydrogenated hydrocarbonaceous stream having a reduced level of halogen and an anhydrous stream comprising a hydrogen halide compound.

  • Patent number: 5314614
    Abstract: The invention provides a process for hydrotreating an organic feedstock containing thermally unstable compounds and a halogen component by means of contacting the organic feedstock and a gaseous recycle stream containing hydrogen and a hydrogen halide compound with a hydrogenation catalyst in a hydrogenation reaction zone to produce a hydrogenated hydrocarbonaceous stream having a reduced concentration of halogen and a halide compound stream. The resulting effluent from the hydrogenation zone is separated to produce a recycle stream containing a hydrogen halide compound.
