An algae treatment method includes: a first step of culturing microalgae in a culture medium having an initial nitrogen concentration of less than 12 mg/L for three days or more; and a second step of performing a thermal treatment of the microalgae that has gone through the first step at a pH of 2.0 or more and 10.0 or less and a temperature of 35 C. or more and 80 C. or less.

The present invention provides a synthetic chemical method for preparing -hydroxylated polyunsaturated fatty acids (PUFAs) including 20-hydroxyeicosatetraenoic acid (20-HETE), 20-hydroxyeicosapentaenoic acid (20-HEPE), and 22-hydroxydocosahexaenoic acid (22-HDoHE) and a method of use thereof for treating cancer and macular degeneration.

The use of bio oil from at least one renewable source in a hydrotreatment process, in which process hydrocarbons are formed from said glyceride oil in a catalytic reaction, and the iron content of said bio oil is less than 1 w-ppm calculated as elemental iron. A bio oil intermediate including bio oil from at least one renewable source and the iron content of said bio oil is less than 1 w-ppm calculated as elemental iron.

Disclosed herein is a catalyst for producing biodiesel, including a carrier having water resistance and an active component supported on the carrier and used in a hydrotreating reaction or a decarboxylation reaction. Since the catalyst for producing biodiesel includes a carrier having strong water resistance, the deactivation of the catalyst due to the water produced through a process of producing HBD can be prevented, thus remarkably improving the long term stability of a catalyst.

A method is disclosed of purifying a recycled or renewable organic material, wherein the recycled or renewable organic material contains one or more impurities selected from a group consisting of silicon compounds, phosphorous, Cl and sterols. Exemplary embodiments include (a) providing the recycled or renewable organic material; (c) heat treating the recycled or renewable organic material at 100 to 450? C.; and (f) hydrotreating the heat treated recycled or renewable organic material in a presence of a hydrotreating catalyst; to obtain purified hydrotreated recycled or renewable organic material.

The invention relates to a process for the hydrogenation of vegetable oils that selectively converts polyunsaturated fatty acids into mono-unsaturated fatty acids, and to the products obtained therefrom. Vegetable oils obtained by the process according to the invention have a particularly high content of monounsaturated fatty acids and are suitable for use as raw materials for the synthesis of chemical intermediates.

The present invention describes a process for treating a feedstock obtained from a renewable source, comprising a step a) of hydrotreating said feedstock, a step b) of separation into at least a light fraction and at least a hydrocarbon liquid effluent, a step c) of removing at least a portion of the water from the hydrocarbon liquid effluent, a step d) of hydroconversion of at least a portion of the hydrocarbon liquid effluent, said hydroconversion step d) being characterized firstly by the use of a bifunctional catalyst comprising a molybdenum and/or tungsten sulfide phase promoted with nickel and/or cobalt and secondly by a ratio between the partial pressure of hydrogen sulfide and of hydrogen at the inlet of the hydroconversion unit of 10 less than 5?10.sup.?5 and a step e) of fractionation of the effluent obtained from step d) to obtain at least a middle distillate fraction.

A composition of branched fatty acids or esters thereof and the processes for preparing such compositions and to a process of producing a composition of branched C10-C24 fatty acids or esters thereof with a high portion, at least 70% by weight, of mono and polybranched C10-C24 fatty acids or esters thereof.

Process for the catalytic hydrogenation of vegetable oils wherein the oil is placed in contact with molecular hydrogen in the presence of a metal catalyst, and the process is performed in the absence of water or in the presence of a quantity of water equal to or less than 5:1 with respect to the weight of the metal catalyst and at a temperature equal to or less than 50 C.
