The present invention describes a process which guarantees the removal of the insoluble polar pollutants present in biodiesel that give rise to the formation of precipitates at temperatures above cloud point and dramatically affect its performance at low temperatures. The biodiesel obtained through the process described in the present invention guarantees that the strictest requirement is fulfilled in international legislation for cold filtration, thereby guaranteeing the production of high-quality industry-grade biodiesel. The process consists basically of two steps: the first is adsorption in a reactor batch and the second is the transfer of the polar chemical components left over from the first step. In both steps, a natural or acid-activated aluminosilicate is used as an adsorbent.

PROCESS FOR OBTAINING A PIPELINE-TRANSPORTABLE HYDROCARBON COMPOSED OF HEAVY AND EXTRA HEAVY CRUDE OIL WITH NON-CONVENTIONAL DILUENTS
This invention provides a process for obtaining, under low pressure conditions, a highly stable, homogeneous hydrocarbon with low viscosity and high retention of volatiles. The hydrocarbon resulting from the process is composed mainly of heavy and extra heavy crude oil, a conventional diluent and a NCD, wherein the components of the NCD are grouped into three types: hydrocarbons with three or less carbon atoms (C-3), hydrocarbons with four carbon atoms (C4) and hydrocarbons with five or more carbon atoms (C5+). The mixture of the defined components has a synergistic effect on the viscosity, stability and homogeneity properties of the final hydrocarbon, making it possible to transport the heavy and extra heavy crude oil which originally has an API between 7 and 25.

PROCESS FOR CONTROLLING THE INJECTION OF DILUENT IN A WELL BOTTOM TO DILUTE EXTRA-HEAVY CRUDE OIL
The present patent application relates to a process for the controlled injection of a lightweight hydrocarbon at an optimal flow, to dilute extra heavy and foamy crude from a deposit. Homogenisation is achieved using the centrifugal energy of a subsoil pump.

Neither the diluent nor an artificial lifting system requires adaptation. In addition, the amount of diluent required is ensured using data available from the well and the lifting system, by means of control software. The process for monitoring process data and controlling the flow of the diluent is iterative and includes a verification routine for calibrating the injection system.

IMPROVED METHOD FOR THE REDUCTION IN ACIDITY IN CRUDE OILS WITH A HIGH NAPHTHENIC ACID CONTENT BY MEANS OF CATALYTIC HYDROGENATION
It has been discovered that the naphthenic acids present in crude oil are carboxylic acids, characterised by being one (or more) aliphatic or naphthenic ring having an associated alkyl group, which is ended by a carboxylic acid group. The naphthenic acids produce atypical corrosion phenomena, given that they can cause a localised attack without the presence of water at temperatures between 473 K and 693 K, hindering the processing of this type of crude oils in refineries. The invention relates to a catalytic hydrogenation process that permits the selective removal of naphthenic acids present in heavy and extra heavy crude oils with a low production of hydrogen sulphides, in particular in crude oil that has not previously been fractionally distilled. The catalyst is formed by an aluminium and/or magnesium-aluminium spinel-type support having active Fe-Mo phases. In addition, the applicant has discovered that the hydrogenation process using Fe and Mo catalysts and/or mixtures thereof surprisingly permits an acid number of 1 mg KOH/g to be reached in crude oils with TAN greater than 4 gm KOH/g, reducing unwanted reactions in the process and prolonging the useful life of the catalyst via the low deposition of metal sulphurs.
