  • Patent number: 9365776
    Abstract: The present invention relates to a process for the hydrotreatment of a vegetal biomass. Specifically, the present invention relates to a process for the hydrotreatment of a vegetal biomass comprising: a) subjecting said vegetal biomass to a hydrotreatment in a first reactor, said hydrotreatment comprises contacting said vegetal biomass in an aqueous medium and a metal oxide, a mixed metal oxide, or a metal-metalloid oxide catalyst comprising at least 35% by weight of metal oxide, mixed metal oxide, or metal-metalloid oxide relative to the total weight of the catalyst, with hydrogen at a pressure in the range of 10 to 400 bar and at a temperature in the range of 50° C. to 300° C. until a predetermined level of the hydrotreatment of said biomass is obtained and wherein the metal oxide, a mixed metal oxide, or a metal-metalloid oxide catalyst comprises nickel. Further, the present invention relates to a metal oxide, mixed metal oxide or metal-metalloid oxide catalyst.

  • Patent number: 6274095
    Abstract: The present invention provides a method for the thermal treatment of material in a rotating conical chamber (4) placed in a housing (1). According to the invention material, brought into the rotating chamber (4) and ejected due to the conical shape, is returned to the chamber (4) for further thermal treatment, without leaving the housing (1). By applying the method of the invention, the thermal efficiency is increased. In addition, wear of the means required for returning material that is to be treated again into the housing (1), is avoided. The invention also relates to two installations for putting the method into practice.
