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.
