Described herein is a system for generating electric power, comprising: an electric-power source (1) having a preferential point of operation; a double-stage inverter (3A, 3B), which transfers the energy from said source to an external a.c.-voltage electrical network (9); a block (5) for identification of the preferential point of operation, which supplies a reference signal according to the conditions of operation of the electric-power source and to the preferential point of operation of said source; a corrector block (10), provided for setting the parameter for control of the boost converter (3A) of the double-stage inverter (3A, 3B) as a function of the reference signal and of a signal of actual operation of said electric-power source, and for maintaining the source in the proximity of the preferential point of operation.

Feedstock originating from renewable sources is converted to hydrocarbons in diesel fuel distillation range by contacting with a supported catalyst comprising VIII group metal / metals, whereby the consumption of hydrogen is decreased.

A feedstock originating from renewable sources is converted to branched and saturated hydrocarbons without heteroatoms in the diesel fuel distillation range by skeletal isomerisation and deoxygenation carried out by hydrodeoxygenation or alternatively by combined decarboxylation and decarbonylation reactions, whereby the consumption of hydrogen is decreased.

The invention provides a method for preparing ethanediol from polyhydroxy compounds comprising starch, hemicellulose, cane sugar, glucose, fructose and fructosan. The method comprises the following steps of: taking the polyhydroxy compounds as reaction raw materials, and taking metals, carbides, nitrides, and phosphides of transition metals in families VIII, IX and X, such as ferrum, cobalt, nickel, ruthenium, rhodium, palladium, iridium, platinum, molybdenum and tungsten as catalytic active components to form a polymetallic catalyst; and performing further catalytic conversion under a hydrothermal condition that the temperature is 120 to 300 DEG C and the hydrogen pressure is 1 to 13 MPa to prepare the ethanediol from the polyhydroxy compounds with high efficiency, high selectivity and high yield. The method for preparing the ethanediol from the polyhydroxy compounds has the outstanding advantages of renewable raw materials, environment-friendly reaction process, and atom economical efficiency. Simultaneously, compared with other techniques taking biomasses as the raw materials, the method has the advantages of simple process and high yield.

The invention provides a method for preparing ethylene glycol from cellulose. In the method, the cellulose serves as a reaction raw material; a multi-metallic catalyst consists of catalytic active components comprising transition metals iron, cobalt, nickel, ruthenium, rhodium, palladium, iridium and platinum of groups 8, 9 and 10, and the metallic state, carbides, nitrides and phosphides of molybdenum and tungsten; and the high-efficiency, high-selectivity and high-yield preparation of the ethylene glycol from the cellulose is realized through a catalytic conversion process under a hydrothermal condition that the hydrogen pressure is 1 to 12 MPa and the temperature is between 120 and 300 DEG C. Compared with the ethylene glycol industrial synthesis route taking ethylene as the reaction raw material, the reaction provided by the invention has the remarkable advantages of regenerative raw material, environmental-friendly reaction process and atom economy.
