Hydroisomerization of gasoline fraction
Patent
·
OSTI ID:6223584
A method is described for producing fractions of paraffin hydrocarbons of the C/sub 4/-C/sub 7/ isostructure, residing in hydroisomerization of a gasoline fraction in the presence of hydrogen on a catalyst at a temperature of 320 to 400/sup 0/C, under a pressure of 20 to 60 atm, a space rate of feeding the gasoline fraction of 1.0 to 1.5 hour/sup -1/; used as a gasoline fraction being a straight run gasoline fraction boiling out within a temperature range of 85 to 160/sup 0/C or 160 to 195/sup 0/C, or a gasoline fraction of the coking process, boiling out within a temperature range of 35 to 85/sup 0/C or 43 to 170/sup 0/C; the above catalyst comprising amorphous nickelalumosilicate and zeolite of the NaY type in the NiCaHY form, in a weight ratio of 60-9:40-10, respectively, the chemical composition of the catalyst being as follows (wt %): Ni, 7-10; Al/sub 2/O/sub 3/, 5-6; SiO/sub 2/, 86-80; Ca, 1-2; H, 1-2. The target product obtained has a high octane number, up to 89-90 according to the motor method in a pure form. The method is carried out under relatively mild conditions. It allows utilization of available, easily accessible low-octane gasoline fractions.
