  • Publication number: 20070006523
    Abstract: The invention relates to chemical industry and is directed to the production of middle distillate from vegetable oils. In the first step of the production method, the fatty acids or triglycerides of said vegetable oils are hydrogenated to give n-paraffins, and in the second step, the n-paraffins are catalytically converted to paraffins with branched chains. Using this process having two steps, a high-quality middle distillate useful as a component of diesel fuels without any particular specifications may be produced.

  • Publication number: 20020062055
    Abstract: A process for producing a middle distillate suitable for example as a diesel fuel, with improved low temperature properties and a low content of aromatic compounds, from a hydrocarbon feed as the starting material by contacting the feed material in a single reaction step, in the presence of hydrogen, and at an elevated temperature and pressure, with a bifunctional catalyst containing a hydrogenating metal component in addition to a molecular sieve and a carrier for the simultaneous removal of aromatics and isomerization of paraffins. The molecular sieve is preferably an aluminosilicate, or a silicoaluminophosphate, the catalyst comprising as the hydrogenating/dehydrogenating component a metal from the group VI or VIII of the periodic table of the elements.
