Abstract

The invention discloses a C7-C10 n-alkane isomerization catalyst which comprises a composite carrier and 0.05-3.0% of platinum by mass based on carrier, wherein the composite carrier comprises 20-70% of MCM-41 molecular sieve by mass, 10-35% of phosphotungstic acid by mass and 10-50% of aluminum oxide by mass. The catalyst is used for the isomerization reaction of the C7-C10 n-alkane, and has relatively high isomerization activity, high product liquid yield and relatively high selectivity of highly branched alkane.

Description

technical field

[0001] The invention is a catalyst for isomerization of n-paraffins and a preparation method thereof, in particular, a C catalyst containing mesoporous molecular sieves in a carrier 7 ~C 10 Normal paraffin isomerization catalyst and preparation method thereof. Background technique

[0002] In recent years, as the country has paid more and more attention to environmental protection, the quality specifications of motor gasoline products have become more and more stringent, and the restrictions on the content of aromatics and olefins in gasoline have become more and more stringent. Isomerized oil is a low-sulfur, olefin-free, benzene-free and aromatic-free environmentally friendly product. It has the advantages of high octane number, low sensitivity, low Reid vapor pressure, and clean combustion. It is an ideal clean gasoline blending with more potential components.

[0003] Early n-alkane isomerization catalysts were mainly Friedel-Crafts type catalysts, whi...
