20110319696 | HYDROISOMERIZATION PROCESS USING MOLECULAR SIEVE SSZ-81 - The present invention is directed to a hydroisomerization process using a new crystalline molecular sieve designated SSZ-81, which is synthesized using a structure directing agent selected from 1,5-bis(1-azonia-bicyclo[2.2.2]octane)pentane dications, 1,5-bis(1,4-diazabicyclo[2.2.2]octane)pentane dications, and mixtures thereof. | 12-29-2011 |
20120024752 | Multi-Stage Hydroprocessing for the Production of High Octane Naphtha - An integrated process is provided for producing high octane naphtha. Hydrocracked naphtha from a hydrocracking reaction zone is contacted with a reforming catalyst that includes a silicate having a silica to alumina molar ratio of at least 200, and a crystallite size of less than 10 microns. Products from the reforming include a reformed naphtha and a hydrogen-rich stream, which is passed to the hydrocracking reaction zone. | 02-02-2012 |
20120024753 | MULTI-STAGE REFORMING PROCESS TO PRODUCE HIGH OCTANE GASOLINE - The present invention relates to a multistage reforming process to produce a high octane product. A naphtha boiling range feedstock is processed in a multi-stage reforming process, in which said process involves at least 1) a penultimate stage for reforming the naphtha feedstock to produce a penultimate effluent 2) a final stage for further reforming at least a portion of the penultimate effluent 3) a regeneration step for the final stage catalyst. The severity of the penultimate stage can be increased during final stage catalyst regeneration in order to maintain the target RON of the reformate product and avoid reactor downtime. | 02-02-2012 |
20120024754 | MULTI-STAGE REFORMING PROCESS WITH FINAL STAGE CATALYST REGENERATION - The present invention relates to a multistage reforming process to produce a high octane product. A naphtha boiling range feedstock is processed in a multi-stage reforming process, in which said process involves at least 1) a penultimate stage for reforming the naphtha feedstock to produce a penultimate effluent 2) a final stage for further reforming at least a portion of the penultimate effluent 3) a regeneration step for the final stage catalyst. The severity of the penultimate stage can be increased during final stage catalyst regeneration in order to maintain the target RON of the reformate product and avoid reactor downtime. | 02-02-2012 |
