Abstract:
1. A process for producing a hydrocarbon fraction containing components boiling in the range typical for diesel fuel comprising contacting a feedstock at least partly derived from a refining process and comprising one or more C 2 to C 10 alkenes with a zeolite catalyst having partially neutralised acidity and a one-dimensional or two dimensional micropore structure consisting of channels made from rings containing between 10 and 12 silicon and/or aluminum atoms at a temperature in the range 373 to 773 K and pressure in the range 0.1 to 200 bar characterised in that the zeolite catalyst contains both protons and basic cations and is a TON zeolite; and producing diesel fuel from the hydrocarbon fraction; and wherein the basic cation is selected from the group consisting of Group IA and Group IIA metal cations; and wherein the basic cations occupy between 10 and 85% of the ion exchange sites in the partially neutralized zeolite catalyst; and wherein the conversion of the feedstock to diesel fuel is greater than the conversion of the feedstock to diesel fuel with the TON zeolite that is not neutralized and conducted at the same temperatures and pressures.
