The invention discloses a
catalytic method for converting alpha-olefin in an
alkane-olefin mixture into internal olefin and application, raw materials and a
solid acid catalyst are carried out in a
fixed bed or a reaction kettle, the
reaction temperature is 50-150 DEG C, the reaction pressure is 15-400 psi, and the reaction environment is an
inert gas
atmosphere; when the reaction is carried out on the
fixed bed, the
mass space velocity of the
solid acid catalyst is 1h <-1 >-20h <-1 >; when the reaction is carried out in the reaction kettle, the conversion frequency of the raw materials is 5000 mol substrate mol acid site density <-1 > h <-1 > to 50000 mol substrate mol acid site density <-1 > h <-1 >; wherein the
raw material is an
alkane-
alkene mixture; the
solid acid catalyst comprises an
active component and a carrier, wherein the carrier contains at least one
inorganic oxide; the
active component has a structure as shown in a formula (1) and / or a formula (2), in the formula (1) and the formula (2), R is
alkyl or phenyl, and n is greater than or equal to 1. According to the
catalysis method provided by the invention, the conversion rate of alpha-olefin can be increased, and the proportion of skeleton
isomerization products and oligomers in internal olefin products can be reduced.
