摘要:Synthesis of enantiopure cis-α-irone from a renewable carbon source Disclosed herein are natural and synthetic enzymes capable of performing a method of producing cis-α-irone. The method comprises providing an enzyme capable of converting psi-ionone to cis-α-irone; and contacting the enzyme and psi-ionone under suitable conditions to produce cis-α-irone. The enzyme may be a methyltransferase from Streptomyces albireticuli (SaMT), a promiscuous bifunctional methyltransferase/cyclase (pMT1) enzyme from Streptomyces, or a modified pMT1 enzyme with at least one substitution. The enzymes allow the in-vivo and in-vitro production of cis-α-irone including the use of glucose as feedstock for the biotransformation into cis-α-irone.

摘要:A method for the synthesis of mixed metal oxide crystalline powders comprises the steps of preparing a raw material mixture containing at least two different metal cations; adding a template material to the mixture and blending it therewith; initiating formation of a mixed metal oxide by calcination of the mixture and the template material, whereby particles of the mixed metal oxides are formed; and thereafter recovering the mixed metal oxide particles. Mixed metal oxide crystalline powders comprise a template material; and metal oxides which form pigment classes of material containing the template material, the pigment classes being selected from the group consisting of borate, garnet, olivine, phenacite, phosphate, priderite, pyrochlore, sphene, spinel and zircon, as well as perovskite crystal classes of material containing the template, all of which have a uniform particle morphology and particle size ranging between about 0.2 to 100 mu with minimal comminution.

标题 :Process and reactor for the preparation of ammonia

摘要:Process and reactor for the preparation of ammonia at elevated pressure and temperature in an ammonia reactor, wherein a process stream of ammonia synthesis gas is successively passed through at least three catalyst beds with intermediate cooling of partially reacted synthesis gas leaving the catalyst beds by heat exchange in heat exchangers arranged between each catalyst bed. The process stream is obtained by combining prior to introduction into a first catalyst bed, a first feed stream of synthesis gas having been preheated through indirect heat exchange during the intermediate cooling of the partially converted synthesis gas and a second feed stream of synthesis gas for adjustment of temperature of the process stream. The first feed stream is passed successively through the interbed heat exchangers for cooling the partially converted synthesis gas and space velocity of the synthesis gas is adjusted to be substantially in the same range in all catalyst beds.

标 题 :Process for producing catalysts for ammonia synthesis by reducing iron oxides
发明人：ECKERT RENE; REITMEIER STEPHAN J; MAIER STEFAN
权利人:CLARIANT INT LTD
摘要:Disclosed is a process whereby completed catalysts can be produced from the iron oxides, and these catalysts can be activated and employed directly after activation for ammonia synthesis from synthesis gas, comprising for example a mixture of nitrogen and hydrogen. A process is also disclosed to produce pre-reduced catalyst precursors, which are first reduced under controlled conditions and subsequently passivated in an oxidizing atmosphere, before they are used in ammonia synthesis as catalysts. These pre-reduced catalysts can be activated significantly more quickly and under milder conditions than the iron oxides.
