Abstract

1,226,807. Reforming hydrocarbons. UNIVERSAL OIL PRODUCTS CO. 19 Aug., 1968, No. 39590/68. Heading C5E. A process for the enhanced production of aromatic hydrocarbons from a hydrocarbonaceous feed containing aromatics comprises the steps of: (a) solvent extracting the feed in a first extractor to produce a first rich solvent phase containing aromatic hydrocarbons and a first hydrocarbonaceous raffinate phase; (b) reforming the first raffinate phase by contacting the raffinate with a reforming catalyst in a reaction zone maintained at reforming conditions; (c) solvent extracting the reformed raffinate in a second extractor to produce a second rich solvent phase containing aromatics and a second hydrocarbonaceous raffinate phase which is recovered; (d) separating the aromatics from the first and the second rich solvent phases; and (e) recovering the aromatics. Suitable solvents include ethylene, propylene, diethylene, triethylene, dipropylene or trimethylene glycol, sulpholane, sulpholene, dimethyl sulphoxide, and N-methyl pyrrolidone. The catalyst for the reforming stage may be platinum and chlorine or fluorine on alumina. The two extract phases may be combined and subjected to common stripping, solvent regeneration and fractionation. The charge stock may comprise hydrocarbons in the gasoline boiling range.
