    摘要: 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), Basolite™ 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. If desired, add a step intermediate between steps a) and b) or preceding step b) wherein the metal organic framework is impregnated with an oxygenated solvent solution of a polymerizable additional carbon source and the polymerizable additional carbon source is thereafter polymerized.

    摘要: Provided is a process for preparing a diaryl ether compound through the dehydration of an aromatic alcohol compound in the presence of a halogenated rare earth element oxide catalyst, providing a reaction vessel having loaded therein a rare earth element oxide; halogenating the rare earth element oxide with a halogen source to form an activated catalyst; and dehydrating an aromatic alcohol compound over the activated catalyst to form the diaryl ether compound, where the halogenating and dehydrating steps occur in the same vessel. The rare earth element oxide is an oxide of a light rare earth element, an oxide of a medium rare earth element, an oxide of a heavy rare earth element, an oxide of yttrium, or a mixture of two or more thereof.
