TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The catalyst comprises a zeolite comprising CON-type zeolites, and TUN-type zeolites. The zeolite is SSZ-26, SSZ-33, CIT-1 or TNU-9. The feed stream comprises normal and singly branched 4-7C paraffins (10 wt.%). The catalyst comprises a Group VIII metal of 0.05-5, (preferably 0.1-1) wt.%. The Group VIII metal is platinum, and/or palladium. Preferred Components: The product stream comprises 2,2-dimethylbutane and 2,3-dimethylbutane, and has a mole ratio of at least 1, preferably at least 5. The hydroisomerization conditions comprise LHSV of 0.75-2.5 h-1, and a hydrogen/hydrocarbon mole ratio of 2-8.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The hydroisomerization conditions comprise a temperature of 150-700 degrees F, preferably 450-600 degrees F, at pressure of 50-2000, (preferably 150-400) psig, a hydrocarbon feed liquid hourly space velocity (LHSV) of 0.5-5 h-1, and a molar ratio of hydrogen to hydrocarbon of 0.5-10. EXAMPLE - Hydroxide solution (6.87 g) of 1,4-bis(N-cyclohexylpyrrolidinium) butane (0.50 mmol/g), 1N sodium hydroxide (3 g), and deionized water (1.09 g) were mixed together in a Teflon (RTM: Polytetrafluoroethylene) liner. Next CAB-O-SIL M-5 (RTM: Fumed silica) (0.54 g) and LZY-62 zeolite Y (0.25 g) were added to the solution and mixed to create a uniform gel. Seeds (0.05 g) were then added to the gel. The liner was then capped and placed in a reactor. The reactor was then fixed in a rotating spit (43 rpm) within an oven heated at 160 degrees C for 7 days. The solid products were recovered from the cooled reactor by vacuum filtration and washed with copious quantities of water, to give SSZ-26 zeolite product. Hydroisomerization of n-hexane was carried out by using the SSZ-26, in a reactor with pure n-hexane as feed, at 500 degrees F. The temperature for maximum isomer yield of the zeolite catalyst was determined by product analysis over a range of successively increased temperatures, until isomer yields in the product stream of each catalyst sample reached a maximum. The hydroisomerization conditions included a pressure of 200 psig, a liquid hourly space velocity of 1 h-1, and a molar hydrogen to hydrocarbon ratio of 6:1. The reaction products were analyzed to give 2,2-dimethylbutane (9.9 mol.%), 2,3-dimethylbutane (12.8 mol.%), 2-methyl-pentane (47 mol.%), and 3-methylpentane (30.3 mol.%).
