TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Material: The isomerization catalyst is an acidic catalyst comprising zeolites, acidic clays, and/or molecular sieves. The zeolite comprises AEL, AFO, AHT, BOG, CGF, CGS, CON, DFO, EUO, LAU, MTT, NES, PAR, TON, MEL, AFI, ATO, ATS, CAN, LTL, MTW, ROG, AET; UTD-1, VFI, FAU, FER, HEU, AFS, AFY, BEA, BPH, CLO, EMT, FAU, GME, MOR, MFI, MEL, and/or MEN. The catalyst comprises both mesopores and micropores. It comprises mesoporous aluminosilicate or a mesoporous metal containing aluminosilicate. The mesoporous aluminosilicate is a mesoporous zeolite. The primary and/or secondary crystalline building units are based on a zeolite comprising zeolite A, Beta zeolite, zeolite X, zeolite Y, zeolite L, zeolite ZK-5, zeolite ZK-4, zeolite ZSM-5, zeolite ZSM 11, zeolite ZSM-12, zeolite ZSM-20, ZSM-35, zeolite ZSM-23, and/or VPI-5. Preferred Ratio: The SiO2/Al2O3 ratio of the zeolite is greater than or equal to5. Preferred Property: The zeolite contains a channel structure having a pore diameter of greater than or equal to6.5 Angstrom . The mesoporous zeolite catalyst material comprises mesopores of 15-500 Angstrom and primary and secondary nanosized zeolite structural units in the walls that separate mesopores.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Material: The branched fatty acid ester is alkyl branched and/or aryl branched. It is methyl, ethyl, propyl, butyl, isopropyl, isobutyl, and/or 2-ethylhexyl esters of fatty acid. The fatty acid is rapeseed, soy, corn, sunflower, and/or safflower. Preferred Process: The branched fatty acid ester is an alkyl branched fatty acid ester prepared by isomerizing a feedstock that comprises unsaturated linear fatty acids in the presence of isomerization catalyst, to obtain a branched fatty acid, followed by esterification of the branched fatty acid with alcohol to obtain an alkyl branched fatty acid ester; isomerizing a feedstock that comprises fatty acid ester in the presence of an isomerization catalyst, to obtain a branched fatty acid esters; and/or isomerizing a feedstock that comprises a vegetable oil which can be used as is, or is further transesterified to an alkylester.
