Adding Hydrogen To Unsaturated Bond Of Hydrocarbon, I.e., Hydrogenation Patents (Class 585/250)
  • Patent number: 8470251
    Abstract: An apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a particulate solid material to form a heavy hydrocarbon slurry and hydrocracked in a slurry hydrocracking unit to produce vacuum gas oil (VGO) and pitch. A first vacuum column separates VGO from pitch, and a second vacuum column further separates VGO from pitch. As much as 15 wt-% of VGO can be recovered by the second vacuum column and recycled to the slurry hydrocracking unit. A pitch composition is obtained which can be made into particles and transported without sticking together.

The reaction involved in the process of the present invention is the selective hydrogenation of glycerin, which takes place by contact of the charge of glycerin carried by hydrogen in a continuous stream system on the catalytic bed containing multi-metal catalysts, specifically prepared for this purpose.

  • Patent number: 7960599
    Abstract: A process for producing industrially important chemicals from renewable resources is disclosed. This “biobased” process employs readily available, renewable resources comprising fatty acids rather than exploiting fossil sources, such as coal and petroleum. In one embodiment of the process 1-octene, along with methyl-9-decenoate and butadiene, is produced from linoleic acid via an enzymemediated isomerization reaction, followed by a metathesis reaction with ethylene. Linoleic acid can be isolated from vegetable oils, such as soybean oil.

  • Patent number: 7939699
    Abstract: Catalysts comprising cobalt on a titania support are produced by mixing together particles of a solid titania support and an aqueous solution of cobalt amine carbonate, and heating to an elevated temperature sufficient to effect decomposition of the cobalt amine carbonate and precipitation of a cobalt species onto said support. The catalysts are useful in hydrogenation and Fischer-Tropsch reactions.

  • Publication number: 20110053020
    Abstract: Nanostructured catalysts and related methods are described. The nanostructured catalysts have a hierarchical structure that facilitates modification of the catalysts for use in particular reactions. Methods for generating hydrogen from a hydrogen-containing molecular species using a nanostructured catalyst are described. The hydrogen gas may be collected and stored, or the hydrogen gas may be collected and consumed for the generation of energy. Thus, the methods may be used as part of the operation of an energy-consuming device or system, e.g., an engine or a fuel cell. Methods for storing hydrogen by using a nanostructured catalyst to react a dehydrogenated molecular species with hydrogen gas to form a hydrogen-containing molecular species are also described.

  • Publication number: 20110046423
    Abstract: Conversion of renewable hydrocarbons to transportation fuels is required to reduce carbon emission, limit the use of fossil fuels, and develop renewable energy sources. Sorbitol, xylitol and trehelose are polyalcohols generated from the liquefaction of various sugars and carbohydrates in biomass from algae, corn, sugarcane, switchgrasses, and biological wastes. Mixtures of aqueous polyols and fuel feedstocks are catalyzed over metal catalysts to produce hexanes, pentanes, and lighter hydrocarbons. By managing the catalyst, reaction conditions and sulfur content, the octane value of the product fuel is dramatically increased.
