Method for isolating an enriched source containing nitrogen heterocycles using monohydroxyl alcohol as treatment agent.

摘要

A method for isolating compounds separately containing organo non-basic and basic heterocyclic nitrogen from a hydrocarbon stream having a boiling point in the range of 232 ° C to 566 ° C, comprising: a) contacting said hydrocarbon stream with an agent selected treatment monohydroxyl alcohols having a density at 25 of less than 0.90 g / cm3 and mixtures thereof, at conditions effective to maintain the reactants in a liquid phase to produce a first stream enriched in organo non-basic heterocyclic nitrogen and one second treated stream having a decreased content of organo non-basic heterocyclic nitrogen; b) separating said first treated stream from said second treated stream; c) separating the organo non-basic heterocyclic nitrogen of said first treated stream; d) contacting said second treated stream with said treating agent and cantidadefectiva mineral acid to produce an enriched organo non-basic heterocyclic nitrogen stream and a treated stream having a decreased content of organo non-basic heterocyclic nitrogen.
