Catalysts based on molecular sieves and methods for selectively hydrogen isomerizing branched paraffins with long linear and / or low branching degrees using the catalysts

摘要

The present invention relates to a method for selectively hydroisomerizing a compound having an n-alkane chain having 10 or more carbon atoms, the method comprising one or more hydrogen-dehydrogenating elements, One or more molecular sieves having a one- or two-dimensional pore network structure, a pore opening formed by 10 oxygen atoms and accessible by a small space, and a distance defined by a crosslinking distance of a small space of 0.70 nm or less And contacting the compound to be treated with a zeolite-containing catalyst such that the catalyst performing the standard n-heptadecane isomerization test has a selectivity of at least 70% for the isomerized product when the conversion is 95%. 5% by weight of at least one hydrogenated-hydrogen-deleting element selected from the group consisting of non-noble metals, Group VIII metals, Group GVIB metals and niobium It is preferable to contain a phase and to contain phosphorus.;The molecular sieve is preferably NU-10, NU-23, NU-87, EU-13 or Theta-1 zeolite.
