CATALYST, A METHOD OF ITS PREPARATION AND A METHOD OF ISOMERIZATION OF OLEFINS WITH USE OF THIS CATALYST Russian patent published in 2005 - IPC

FIELD: chemical and petrochemical industries; isomerization of olefins.

SUBSTANCE: the invention is dealt with of the field of deposition on carbon materials of catalysts of the basic nature being of interest for processes of isomerization of olefins. There is a description of a catalyst of isomerization of olefins containing metal sodium deposited on a composite porous carbon material, which represents a three-dimensional porous carbon die with the following structural characteristics: d₀₀₂ =_{0.343-0.350 nm, the average size of the crystallite in a direction of "a"-La=l-14 nm, the average size of the crystallite in a direction of "c"-Lc=2-12 nm, real density of 1.8-2.1 g/cm³, with distribution of pores by sizes having a maximum in the range of 20-200 nm and an additional maximum in the range of 1-20 nm. Also there is a description of a method of preparation of the catalyst providing for deposition of metal sodium on the composite porous carbon material and a method of isomerization of olefins with use of this catalyst. The technical result is a possibility to conduct the process of isomerization at low temperatures, increased catalytic activity and selectivity, decreased output of by-products.}

EFFECT: the invention ensures a possibility to conduct the process of isomerization at low temperatures, increased catalytic activity and selectivity, decreased output of by-products.
