  • Patent number: 9353036
    Abstract: Subject-matter of the invention is a process for producing fatty alcohols by catalytic hydrogenation of fatty acid methyl ester (FAME), in which the FAME initially is hydrogenated to fatty alcohol (FA). The fractions of non-converted FAME remaining in the hydrogenation product are converted to wax ester and methanol in a succeeding transesterification step with FA. According to the invention, catalysts on the basis of magnesium oxide or hydrotalcite are used. After separating the methanol and the FA as target product, a stream enriched in wax ester is recirculated to the hydrogenation reactor.

  • Patent number: 9321643
    Abstract: The present invention concerns a process for producing synthesis gas by steam reforming a hydrocarbon load in a reforming furnace provided with a combustion chamber and a convection chamber; the combustion chamber includes vertical tubes filled with catalyst wherein a mixture of hydrocarbons and steam circulates from top to bottom recovering raw synthesis gas at the bottom of the tubes, and burners disposed in rows heat the tubes; the convection chamber discharges fumes containing the gases produced by the combustion. The process also comprises steps of using the heat contained in the fumes for preheating and/or heating various fluids related or unrelated to the process. In the event of the reduction of the mass flow of fumes, the quantity of energy to be transferred into the convection area is maintained by supplying a supplementary gaseous flow to the combustion area.

  • Patent number: 9321131
    Abstract: The invention relates to a method for the laser welding of metal parts that comprises generating a CO2 laser beam, dispensing a protection gas jet made of said gas or gas mixture in the direction of the junction plane between the parts, melting and evaporating the metal of the metal parts with the laser beam in order to generate a metal vapor capillary with the simultaneous generation of a metal plasma that propagates outside the metal vapor capillary and thus forms a metal plasma plume above said junction plane. The protection gas jet is further directed towards the metal plasma plume forming above the junction plane. The gas jet is preferably directed so that the latter comes flush with the top of the metal plasma plume and impinges on the part(s) at a location where the metal of said parts has not been molten by the beam.
