Abstract From the Canadian patent

A method for producing fractions of paraffin hydro- : carbons of the C4-C7 isostructure, residing in hydroisomerization of a gasoline fraction in the presence of hydrogen on a catalyst at a temperature of 320-400°C under a, pressure of 20 to 60 atm. a space rate of feeding the gasoline fraction of 1.0 - 1.5 hour-1; used as a gasoline fraction being a straight run gasoline fraction boiling out within a temperature range of 85-160°C or 160-195°C or, a gasoline fraction of the coking process boiling out with-, in a temperature range of 35-85°C or 43-170°C; the above catalyst comprising amorphous nickelalumosilicate and zeolite of the NaY type in the NiCaHY form in a weight, ratio of …
