Production of Diesel Fuel Blends

Diesel Fuel Blends. Modern oil refining performs several important functions, among which improvement of the low temperature performance of diesel fuel performance and increased depth of hydrofining.

Until recently, the production of fuel with good low temperature performance was done by either reducing the end of fuel boiling from 360ºС to 340ºС (330ºС for arctic fuel), or by dilution with kerosene. In both cases, the economic viability was questionable. In many cases, diesel fuel performance suffered, with reduction of cetane number and lubricity.

Therefore, gradual implementation of modern catalytic hydrogenation processes into oil refining began: hydroisomerization and catalytic deparaffinization. The processes allow to change diesel fuel, optimizing their hydrocarbon composition.
