摘要: Abstract In this study long-chain n-paraffins in the range from nonane to heptadecane were converted over bifunctional zeolite Y, USY, ZSM-3, ZSM-20 and BETA catalysts presence of hydrogen. n-Paraffins can be selectively into branched isomers, provided hydrogenation-dehydrogenation function is balance with acid catalyst. The equilibration two catalytic functions depends on catalyst as well carbon number feed. For each there exists an optimum loading noble metal which chain length n-paraffin If geometry dimensions pores are such that hydrocracking suppressed by molecular shape-selectivity, yield isomerisation improved substantially. mesopores Y crystals reflected yield.
