CATALYST FOR COMBINED OBTAINING OF WAXY FUELS AND ISOPARAFFIN OILS AND METHOD FOR COMBINED OBTAINING OF WAXY FUELS AND ISOPARAFFIN OILS IN PROCESS OF ISOMERISATION/CRACKING OF HIGH-PARAFFIN RAW MATERIAL WITH APPLICATION THEREOF

摘要

FIELD: chemistry.;SUBSTANCE: catalyst contains zeolite SAPO-41 or MgAPSO-41, which has acidity, determined by ammonia TPD method, 0.30-0.75 mmol/g with the following component content, wt %: platinum 0.1-0.5; zeolite SAPO-41 or MgAPSO-41, which has acidity, determined by ammonia TPD method, 0.30-0.75 mmol/g 20.0-80.0; aluminium oxide - the remaining part. In order to realise combined obtaining of waxy jet or Diesel fuel and isoparaffin oil process of isomerisation/cracking of high-paraffin raw material is carried out in flow mode with contact of flow of gas-liquid mixture, consisting of high-paraffin raw material and hydrogen, with immobile layer of above said catalyst at temperature 380-440°C, pressure 2.0-4.0 MPa, volume rate of raw material supply 1.0-1.5 h^-1, hydrogen/raw material ratio 1000:1 nl/l. after separation of hydrogen-containing gas obtained total product of isomerisation/cracking process is divided with separation of target products or is subjected to hydrofinishing and further separation with isolation of target products.;EFFECT: increase of output and quality of waxy Diesel or jet fuel and isoparaffin oil from crude oil or synthetic high-paraffin raw material.;4 cl, 5 tbl, 8 ex
