FUEL COMPOSITION "VIEZEL" AND PROCEDURE FOR ITS PRODUCTION Russian patent published in 2011 - IPC C10L1/18 C10L1/22 C10L5/00 

FIELD: oil and gas production.

SUBSTANCE: composition includes oil diesel fuel, biological component such as vegetable or animal oil or fat and mixture of fuel additives. Mixture of fuel additives contains a cetane increasing additive, a dehydrating additive, a detergent additive, a lubricating additive and a depressant. The procedure consists in filtering biological component through a polyester filter and in bringing non-soluble and unsaponifiables to a specified value. Filtrate is settled in conic tanks, and sedimentation is removed. Further, there is added oil diesel fuel which is mixed at certain temperature. Mixture of fuel additives is added to premix and mixed. Thus produced mixture is pumped over to conic tanks, is conditioned at ambient temperature, is settled, and sedimentation is removed. Successively, mixture is filtered, centrifuged in a centrifugal separator and prepared fuel composition is pumped over to storage tanks.

EFFECT: produced fuel is equivalent to summer diesel fuel of 2-D grade from viewpoint of engine power and rpm; it facilitates more pure combustion and is essentially less expensive; also, composition functions as biocide for bacteria growth inhibition.
