  • Patent number: 9833774
    Abstract: Preparation of a catalyst suitable for use in Fischer-Tropsch Synthesis reactions using a two step process in which the steps may be performed in either order. In step a), impregnate an iron carboxylate metal organic framework selected from a group consisting of iron-1,3,5-benzenetricarboxylate (Fe-(BTC), Basoliteā„¢ F-300 and/or MIL-100 (Fe)), iron-1,4 benzenedicarboxylate (MIL-101(Fe)), iron fumarate (MIL-88 A (Fe)), iron-1,4 benzenedicarboxylate (MIL-53 (Fe)), iron-1,4 benzenedicarboxylate (MIL-68 (Fe)) or iron azobenzenetetracarboxylate (MIL-127 (Fe)) with a solution of a promoter element selected from alkali metals and alkaline earth metals. In step b) thermally decompose the iron carboxylate metal organic framework under an inert gaseous atmosphere to yield a catalyst that is a porous carbon matrix having embedded therein a plurality of discrete aliquots of iron carbide.

  • Publication number: 20090108239
    Abstract: The present invention relates to composite ceramic membranes for use in chemical processes such as the separation of molecules, sometimes referred to as molecular sieving, preferably in combination with chemical conversion of molecules selected from a composition of different molecules, e.g. the selective partial or full oxidation. The composite membrane of the invention offers a combination of molecular sieving and oxygen transport that makes the composite membrane suitable for the selective oxidation of hydrocarbons from a feed comprising a mixture hydrocarbons. The composite membrane of the invention comprises a first layer containing an oxygen transporting material (OTM), e.g. perovskite, and, in association with the first layer, a second layer, containing a molecular sieve layer, e.g. a zeolite.

  • Publication number: 20070190631
    Abstract: A reaction product is made by flowing a liquid containing a reactant through a porous ceramic honeycomb wherein the porosity of the walls of the honeycomb are such that the liquid containing the reactant substantially penetrates into the walls and the reactant reacts as the liquid containing the reactant flows from the inlet end to the outlet end of the monolithic ceramic honeycomb.
