  • Patent number: 8821692
    Abstract: Method for fast pyrolysis of lignocellulose including: mechanically comminuting the lignocellulose to lignocellulose particles; at least one of completely drying and preheating the lignocellulose particles; mixing the lignocellulose particles with heat transfer particles so as to provide a mixture; heating the heat transfer particles, prior to the mixing, to a temperature between 500° C. and 650° C.; and heating, in a pyrolysis reactor with oxygen excluded, the lignocellulose particles using the heat transfer particles so as to establish a temperature between 400° C. and 600° C. for 1 to 50 seconds and so as to react the lignocellulose particles so as to provide pyrolysis coke, pyrolysis condensate, and pyrolysis gas.

  • Patent number: 8043391
    Abstract: A method is provided for producing and preparing fast pyrolysis products from a biomass for entrained-flow pressure gasification that includes: heating of the biomass under exclusion of oxygen in a pyrolysis reactor, a temperature of between 400 to 600° C. being established for one to 50 seconds, such that the biomass reacts to form porous pyrolysis coke, pyrolysis condensate and pyrolysis gas; and drawing off the pyrolysis gas; condensing vaporous constituents of the pyrolysis condensate in a plurality of condensation stages so as to: condense, in a first condensation stage, at temperatures above the dew point of water, a low-temperature carbonization tar from the vaporous constituents; and condense and separate at temperatures between 0° C. and the dew point of water, in at least one subsequent condensation stage, an aqueous solution of oxygen containing organic compounds.

  • Patent number: 6518446
    Abstract: The invention relates to a method for producing formoxysilane. A silane of the formula RnSiH4−n, wherein R is an organic or inorganic substituent and n=0, 1, 2 or 3, is converted with carbon dioxide in a solvent in the presence of a catalyst consisting of a compound of a transitional metal pertaining to the subgroup VIIIb of the periodic system. The aim of the invention is to find a catalyst for the method mentioned above. The catalyst should be more simple, easy to produce and thus more cost-effective, easily available in large quantities and being provided with high activity and product selectivity. To this end, a halide of the transitional metal or a compound of the transitional metal are used as catalyst. Said compound is produced by converting a halide of the transitional metal with a nitrile in the presence of the silane of the formula RnSiH4−n.

  • Patent number: 6342149
    Abstract: A method for carboxylating terminal alkynes that have at least one additional aliphatic carbon atom in an &agr; position and that do not have a proton which has a higher acidity than that of the proton of the terminal triple bond. In an undivided electrolysis cell equipped with a cathode and an anode, a solution of the terminal alkyne in an aprotic solvent is acted upon by carbon dioxide at a pressure higher than atmospheric pressure. The invention provides a method in which carbon dioxide is selectively inserted between the terminal C—H bond, without disturbing the triple bond, and can be carried out without a catalyst or catalyst precursor.

  • Patent number: 6291390
    Abstract: The invention relates to the reaction of 1,3-butadiene and carbon dioxide. The invention aims at providing a catalyst for said reaction, which can be easily recovered and does not contaminate the final product. The invention also relates to a method for producing &dgr;-lactone. According to the invention, a phosphinoalkyl-functionalized polystyrene is used to produce such a catalyst. The catalyst can be obtained by reacting phosphinoalkyl-functionalized polystyrene with (&eegr;5-cyclopentadienyl) (&eegr;3-allyl)palladium. The catalyst is used in the method to produce &dgr;-lactone.

  • Patent number: 5641723
    Abstract: The present invention relates to a process for preparing highly active doped supported catalysts from an organic or inorganic support material and a catalyst metal precursor, characterized in that the support material is doped with lower-valent readily decomposable metal compounds of at least one metal of groups 4, 5 and/or 6 of the Periodic Table in the presence of solvents prior to or simultaneously with the operation of coating with the catalyst metal precursor in the form of metal particles, metal clusters or metal colloids of at least one metal of groups 6, 7, 8, 9, 10 and/or 11 of the Periodic Table, wherein the metal(s) of the catalyst metal precursor and the metal(s) of the lower-valent metal compound have been derived from different groups of the Periodic Table, optionally followed by an after-treatment with oxygen, and all steps are carried out at a temperature of between -18.degree. C. and +25.degree. C.The invention further relates to the use of the catalysts prepared by said process.
