  • Publication number: 20130245299
    Abstract: The present invention relates to an improved process for the production of conjugated polyunsaturated fatty acids (PUFA), preferably conjugated linoleic acid (CLA), using finely dispersed heterogeneous metal catalysts on a mesoporous support, in the absence of Hg. The present invention also relates to a method to increase the large microporosity and (optionally) the small mesoporosity of a zeolite, thus obtaining a modified zeolite having a large and highly accessible internal surface.

  • Patent number: 8217206
    Abstract: The present invention is a process for converting methane to methanol, comprising: feeding methane and gaseous air or oxygen or gaseous air enriched with oxygen to a reactor under an elevated pressure; said reactor having an internal surface, made of silica or coated with silica, surrounding a zone in which said gases react; and reacting said gases in said reaction zone at an elevated temperature at conditions effective to produce methanol and for valuable oxygenates. Advantageously the internal surface is made of quartz or coated with quartz Advantageously the internal surface, made of silica (advantageously quartz) or coated with silica (advantageously quartz), is treated with HF before the conversion of methane to methanol. Advantageously the reaction is carried out in the absence in said reaction zone of any added material which measurably affects the rate of the reaction or the yield of the product. Advantageously the reactor is operated under a pressure from 1 to 7.5 MPa.

  • Patent number: 8080692
    Abstract: The invention relates generally to the production of oxygenated hydrocarbons such as lower alcohols and more preferably 1,2-propanediol. More particularly, this invention comprises a single-step catalytic process for the catalytic production of lower alcohols such as methanol, ethanol, ethylene glycol and 1,2-propanediol from glycerol in aqueous medium. The catalyst comprises a metal selected from the Group VIII transition metals, preferably platinum, alloys thereof and mixtures thereof and a microporous carrier, preferably a faujasite-type zeolite.

  • Patent number: 7960585
    Abstract: The present invention relates to a process for preparing secondary amides with good selectivity by carbonylating a corresponding tertiary amine with carbon monoxide in a reaction mixture in the presence of a metal catalyst and in the presence of a halogen containing promoter. The metal catalyst comprises palladium. A same or even a much better catalytic activity can be obtained with palladium than with the much more expensive rhodium, especially when the palladium is used in a low concentration. Moreover, also a good selectivity can be achieved.

  • Patent number: 7790600
    Abstract: A method is provided for incorporating zeolite crystals in patterned structures, the zeolite crystals having pores (channels) with an orientation which is defined by the topology of the zeolite crystal type and the geometry of the patterned structure, resulting in pores parallel with the length axis of the patterned structures. The patterned structures may be vias (vertical contacts) and trenches (horizontal lines) in a semiconductor substrate. These zeolite crystals can advantageously be used for dense and aligned nanocarbon growth or in other words growth of carbon nanostructures such as carbon nanotubes (CNT) within the pores of the zeolite structure. The growth of CNT is achieved within the porous structure of the zeolite crystals whereby the pores can be defined as confined spaces (channels) in nanometer dimensions acting as a micro-reactor for CNT growth.

  • Publication number: 20090269330
    Abstract: The invention relates to a mixture (a) of fatty acid triglycerides having a slip melting point above 500 C, the fatty acid composition of said mixture (a) comprising at least two different fatty acids and comprising from 20 to 95% by weight of saturated fatty acids and 80 to 5% by weight of unsaturated fatty acids, and wherein at least one fatty acid triglyceride (a1) from said mixture (a) bears the same saturated fatty acid residue on each position of the glycerol moiety and corresponds to at least 10% by weight of said mixture (a).
