Selectively adsorbing multibranched paraffins
Abstract
Abstract A PROCESS FOR THE SEPARATION OF HYDROCARBONS UTILIZING A CRYSTALLINE ALUMINOSILICATE ADSORBENT CONTAINING A SPECIFIC CATION ION-EXCHANGED THEREON AND A SPECIFIED RANGE OF WATER CONTENTS TO PROVIDE A SELECTIVE ADSORPTION OF A HYDROCARBON TYPE FROM A FEED STREAM CONTAINING A MIXTURE OF HYDROCARBONS. SPECIFICALLY, THE SEPARATION INVOLVES SELECTIVELY SEPARATING MULTIBRANCHED PARAFFINS FROM A FEED STREAM WHICH CONTAINS A MIXTURE OF MULTIBRANCHED PARAFFINS TOGETHER WITH SINGLY BRANCHED PARAFFINS AND/OR NORMAL PARAFFINS. THE SEPARATION CAN TAKE PLACE UTILIZING BATCH METHODS, MOVING BED SYSTEMS, OR SIMULATED MOVING BED COUNTERCURRENT FLOW SCHEMES. BOTH LIQUIED PHASE AND VAPOR PHASE OPERATIONS ARE ANTICIPATED. SPECIFIC FEEDSTOCKS UTILIZED IN THIS PROCESS INCLUDE HIGH OCTANE COMPONENTSNAMELY, THE C5 AND C6 HYDROCARBONS AND SPECIFICALLY DIMETHYLBUTANES, METHYLPENTANES AND THE NORMAL HEXANES AND PENTANES.
