Abstract:
The invention concerns doped catalyst on alumino-silicate support with adjusted macropore content and hydrocracking/hydroconversion and hydrotreatment methods using same. The catalyst comprises at least one hydro-hydrogenating element selected from the group consisting of the elements of group VIB and group VIII of the periodic table, a controlled amount of phosphorus (optionally combined with boron and/or silicon) as doping element, and a non-zeolite alumina-silica-based support containing an amount between 5 wt. % and 95 wt. % of silica (SiO2).
Abstract:
An exhaust gas purification catalyst of the present invention contains at least a precious metal coated with lanthanum-containing alumina. Therefore, it is possible to provide: an exhaust gas purification catalyst which can (i) have an increase in heat resistance, and (ii) inhibit the precious metal from being mixed in alumina and therefore inhibit the precious metal from forming a solid solution in combination with alumina; and a method for efficiently purifying, by use of the catalyst, an exhaust gas emitted from an internal-combustion engine.
Abstract:
The invention relates to a hydrocarbon composition useful as a fuel and/or combustible containing: - a gasoil component (A), - a gasoline component (A1) - a hydrocarbon component of a biological origin (B), wherein the hydrocarbon component of a biological origin is obtained starting from a mixture of a biological origin (C) containing esters of fatty acids, possibly with aliquots of free fatty acids, by means of a process which comprises a hydrodeoxygenation step of the mixture of a biological origin and possibly a hydroisomerization step of the product resulting from the hydrodeoxygenation.
Abstract:

Abstract:
A catalyst for FT synthesis which, in the FT method, is high in a CO conversion and small in the formation of a gaseous component and can stably perform an FT synthesis reaction and enhance the productivity of hydrocarbons, and a method for producing hydrocarbons using the catalyst, are provided. A catalyst for Fischer-Tropsch synthesis comprising a support containing manganese carbonate as a main component, wherein the support contains at least one metal having an activity to the Fischer-Tropsch reaction; and a method for producing hydrocarbons using this catalyst.
Abstract:
The invention relates to a method for breaking down ethanol into C 1 units in a prereformer. According to said method, ethanol and water vapor are reacted on a catalyst comprising platinum on a carrier containing a mixture of ZrO 2 and CeO 2 at a temperature in the range of 300 to 550°C.
Abstract:
Propylene glycol is produced by a method of producing propylene glycol, the method including: obtaining propylene glycol by performing catalytic hydrogenation of glycerol in the presence of a catalyst, the catalyst containing zinc oxide and at least one of copper and copper oxide, and the catalyst, after being reduced at 180°C to 230°C in the presence of hydrogen, showing a half width of from 0.4 to 1.1 of a peak having a peak top at a position at which a diffraction angle (2θ±0.2°) is 43.1° in an X-ray diffraction pattern obtained using CuKα as a radiation source.
