The present invention relates to a process for converting vegetable oils, animal fats, residual edible oils and carboxylic acids into renewable liquid fuels, such as bionaphtha, bioJET-A1 and renewable diesel, for use in a mixture with fossil fuels. The process consists of two steps: hydrotreating and hydrocracking. The effluent from the hydrotreatment step presents aromatics, olefins and compounds resulting from the polymerization of esters and acids in its composition. This fact occurs due to the use of partially reduced catalysts and without injection of sulfide agent and allows obtaining a bioJET-A1 with adequate quality for use in a mixture with fossil kerosene. At the same time, the process generates, in addition to products in the distillation range of naphtha, kerosene and diesel, high molecular weight linear paraffins (with up to 40 carbon atoms).

Embodiments of the disclosure include processes for selective ring-opening of cycloparaffins in hydrocarbon feeds to produce hydrocracked cycloparaffins. In particular, the process comprises contacting a hydrocarbon feed comprising cycloparaffins with hydrogen and a catalyst comprising an unsulfided, low-acidity, metal-containing zeolite under hydrocracking conditions; wherein the metal is selected from the group consisting of platinum, nickel, rhodium and mixtures thereof. The processes are useful for upgrading petroleum streams to lubricant base stocks.
