Method for selective hydrogenation isomerization of high-grade paraffins having straight chain and / or few branching chains using molecular sieve catalysts

摘要

The present invention relates to a process for the selective hydrogenation of a compound having at least one n-alkane chain having at least 10 carbon atoms, characterized in that the compound to be treated comprises at least one hydrogenation-dehydrogenating element, Contacting the catalyst with a catalyst comprising at least one molecular sieve having a 1-dimensional or 2-dimensional pore network defined by 10 oxygen atoms and a distance between the pores of less than 0.70 nm, said catalyst comprising n-heptadecane Lt; RTI ID = 0.0 95% / RTI under isomerization standard test. The molecular sieve is preferably NU-10, NU-23, NU-87, EU-13 or Theta-1 zeolite.
