Present invention relates to a novel process for purification of lipid material for further use as such as e.g. a source of fuel or chemicals.

The invention relates to a process for purification of oil by heat treatment in order to degrade phospholipids present in the non-purified oil.

A membrane based separation method is for the separation or enrichment of one or more unsaturated compounds from mixtures of chemically similar organic compounds having a different degree of unsaturation, using a membrane, such as an inorganic membrane, functionalized with a metal, such as silver.

An inorganic membrane, preferably modified or grafted with an organic functional group, is further functionalized with a metal, such as silver, for use in the membrane based separation methods.

The present invention relates to a process for producing cycloalkenamer-containing compositions, comprising the steps of: a) converting at least one cycloalkene by ring-opening metathetic polymerization to obtain a polyalkenamer-containing product mixture, and b) working up the product mixture to remove monomers and oligomers of the cycloalkenes to obtain the polyalkenamer-containing composition by extraction with CO.sub.2, whereby the polyalkenamers are polymers of cycloalkenes which comprise at least five cycloalkane monomer units, wherein the extraction comprises at least two stages: b0) an extraction with liquid CO.sub.2, then b1) an extraction with supercritical CO.sub.2, then b2) an extraction with gaseous CO.sub.2, then b0) an extraction with liquid CO.sub.2, then and then b3) an extraction with supercritical CO.sub.2.

A process for making olive oil having a high polyphenol content and, in particular a high hydroxytyrosol content, comprises the conventional steps of transforming (II) olives (1) into an oily must (5); of resolving (V) the later into an oily juice (7), from which a base olive oil (8) is obtained, and into an aqueous juice (6) containing most of the polyphenols; and of separating (VII) the vegetation water (9) from the aqueous juice (6). Moreover, according to the invention, steps are provided of removing water (XV) from the vegetation water (9), preferably by evaporation, so as to obtain a polyphenol-enriched concentrate (11); and of mixing (XIX) the concentrate (11) with the base olive oil (8), so as to transfer said polyphenols from the former to the latter and to obtain a final polyphenol-enriched oil (12), along with an exhausted concentrate (11). The step of removing water causes a polyphenol concentration increase, to enhance their interphase transfer, and, at the same time, it causes a viscosity and density increase, which makes the water phase, during the contact with the oil, less prone to form emulsions than the methods of prior art. The high polyphenol concentration remarkably improves the organoleptic quality of the oil and makes the latter more stable, besides producing well-known advantageous effects for the consumer's health. According to further aspects of the invention, an apparatus is provided for making such oils, as well as a concentrate for use in olive oils and also in any other vegetable or animal food oil, in cosmetics, bio-repellent products and the like.

There is described a biodiesel composition and process for producing biodiesel and related products. There is also described related fuels and fuel blends comprising biodiesel. The biodiesel composition may be prepared from a mixture comprising fats, oils and greases from sewer waste.

A method for producing liquid fuel components from renewable oil. A fresh feedstock including saturated fatty acids is subjected to dilution by an organic lipophilic solvent. The solvent has a low phosphorus and metal impurity content, less than 5 ppm and less than 10 ppm, respectively. Dilution is performed before and/or during purification by at least one pretreatment process for removal of phosphorus and metal impurities. Subsequently, the resulting purified feedstock is fed into at least one post-treatment process suitable for producing liquid fuel components.

Apparatus for filtering used cooking oil includes a container, an inner cup, and a filter pad. The apparatus can be configured to remove undesirable impurities from liquid. For example, the apparatus can be configured to remove total polar molecules and lovibond color red from used cooking oil.
