| 20100152517 | EXTRACTION OF ASO FROM SPENT SULFURIC ACID USING LIQUID SO2 - A process for the regeneration of spent sulfuric acid including contacting spent sulfuric acid containing acid soluble oils (ASO) with sulfur dioxide to extract at least a portion of the ASO from the spent sulfuric acid into the sulfur dioxide. The sulfuric acid phase having a reduced ASO content and a sulfur dioxide phase containing at least a portion of the ASO may be recovered. The resulting sulfuric acid and sulfur dioxide phases may be further separated to recover ASO, sulfur dioxide, and sulfuric acid. | 06-17-2010 |
| 20130274534 | PARAFFIN DISPROPORTIONATION WITH ZEOLITE Y - Methods relate to disproportionation of hydrocarbons utilizing a zeolite catalyst. The methods include reacting pentanes in contact with ultrastable zeolite Y having a silica to alumina ratio of less than 80 to disproportionate the pentanes into butanes and hexanes. The ultrastable zeolite Y is defined by having a sodium oxide content of less than 1% by weight. | 10-17-2013 |
| 20150025291 | Molecular Sieve Material, Its Synthesis and Use - A molecular sieve material, EMM-17, has in its as-calcined form an X-ray diffraction pattern including the following peaks in Table 11: | 01-22-2015 |
| 20150329444 | CATALYTIC DISPROPORTIONATION OF PENTANE USING IONIC LIQUIDS - Processes for the disproportionation and isomerization of a C | 11-19-2015 |
| 20160159710 | DISPROPORTIONATION OF HYDROCARBONS USING SOLID ACID CATALYSTS - A hydrocarbon disproportionation process is described. The process includes contacting a hydrocarbon feed in a disproportionation reaction zone with a disproportionation catalyst in the presence of hydrogen and an added chloride promoter under disproportionation conditions including to obtain disproportionation products, wherein the disproportionation catalyst comprises a solid catalyst comprising a refractory inorganic oxide having a metal halide dispersed thereon. | 06-09-2016 |
| 20160159711 | FLEXIBLE UNIT FOR ISOMERIZATION AND DISPROPORTIONATION OF HYDROCARBONS USING SOLID ACID CATALYSTS - A flexible hydrocarbon conversion process utilizing the same reaction zone for isomerization and disproportionation is described. The feed and type of products are selected. The hydrocarbon feed is contacted with a catalyst and in the presence of hydrogen and an added chloride promoter. The catalyst comprises a solid catalyst comprising a refractory inorganic oxide having a metal halide dispersed thereon. The operating conditions are varied depending on whether isomerization or disproportionation is desired. | 06-09-2016 |
| 20160185688 | HYDROCARBON PROCESSING APPARATUSES AND PROCESSES FOR PRODUCING N-PENTANE AND ISOBUTANE - Hydrocarbon processing apparatuses and processes for producing n-pentane and isobutane are provided herein. In an embodiment, a process for producing n-pentane and isobutane includes providing a hydrocarbon feed stream that includes C4 and C5 hydrocarbons. A recycle stream that includes C4+ hydrocarbons and the hydrocarbon feed stream is combined to produce a combined feed stream. The combined feed stream is separated to produce an iC4 product stream, an nC5+ product stream, and an iC5/nC4 feed stream. The iC5/nC4 feed stream is simultaneously disproportionated and isomerized in an isomerization zone to produce an intermediate stream that includes C3-C6 hydrocarbons. The C3-C6 hydrocarbons in the intermediate stream are separated to produce a C3− stream and the recycle stream that includes C4+ hydrocarbons. | 06-30-2016 |
