Abstract: A rack support and method of use. The support rack can include a plurality of support slats mounted to a support base. The support slats cooperatively provide a plurality of article mounting channels, and article mounts can be slidably mounted in the channels in order to provide a variety of orientations of the article mounts with respect to the support base. In one embodiment, the support channels are T-shaped, and the article mounts have T-shaped mounting ends that may slidably mount with the T-shaped support channels. Other support channel and mounting end shapes may be used. In some embodiments, the rack support may be used to store articles on a wall with increased article density, economy, reliability, safety, and/or usability.

Abstract: Methods and systems of treating an oil shale formation using an in situ thermal process are described herein. A method of treating an oil shale formation in situ includes providing heat from one or more heat sources to at least a portion of the formation; allowing the heat to transfer from at least the portion to a selected section of the formation substantially by conduction of heat; pyrolyzing at least some hydrocarbons within the selected section of the formation; and producing a mixture from the formation.

Abstract: The instant invention relates to a method for preparing a hydrotreating catalyst having improved hydrodenitrification activity by impregnating an alumina supported Group VIB/Group VIII hydrogenating catalyst with a liquid form of a silicon compound having the general formula ##STR1## wherein U, V, W, X, Y, and Z can individually be --R, --OR, --Cl, --Br, --SiH.sub.3, --COOR, --SiH.sub.n Cl.sub.m, R being either hydrogen, or an alkyl, cycloalkyl, aromatic, alkyl aromatic, alkylcycloalkyl radical having from 1 to 30 carbon atoms, "n" and "m" being whole numbers in the range of from 1 to 3 and "a" being a whole number in the range of from 0 to 80, in an amount sufficient to deposit from about 2 to about 8 percent by weight of the total catalyst of Si, and subsequently calcining said impregnated catalyst at a temperature ranging from about 300.degree. C. to about 600.degree. C. in an oxidizing atmosphere.

Abstract: The present invention relates to catalysts suitable for hydrogenating aromatics and olefins in hydrocarbon feedstocks boiling between about 125.degree. C. and about 625.degree. C. as well as the process for carrying out the hydrogenation. The catalysts consist of one or more Group VIII noble metal(s) on a support wherein the support is a Y-type zeolite prepared by contacting a starting Y-type zeolite having a unit cell size less than about 24.65, preferably less than about 24.4 angstroms, a silica to alumina molar ratio greater than about 5, preferably by greater than about 25 and an alkali metal content of less than about 0.30, preferably less than about 0.15 percent (basis metal) with one or more aqueous solution(s) comprising alkali(ne-earth) metal ions under conditions sufficient to provide a final alkali metal content (measured in terms of gram equivalent weight per gram of zeolite) of at least about 1.

Abstract: This process selectively isomerizes the double-bonds of linear olefins without isomerizing the double-bonds of branched olefins. The process is carried out by contacting a mixture of linear olefins and branched olefins at a temperature ranging from about -10.degree. C. to about 250.degree. C. with a zeolite having an alkali metal deposited thereon.

Abstract: The instant invention comprises an improved hydrorefining process which comprises contacting hydrocarbonaceous oil feed and hydrogen with a catalyst comprising a hydrogenation component selected from the group consisting of Group VIB metal component, Group VIII non-noble metal component and mixtures thereof, optionally comprising a phosphorous-containing component or compound, and an alumina-containing support, at hydrorefining conditions, wherein the improvement comprises heating the catalyst in substantially non-sulfided form at initial start-up from a temperature below about 450.degree. F. to hydrorefining temperature at an average rate of less than 30.degree. F. per hour in the presence of hydrogen and a start-up hydrocarbonaceous oil feed having a sulfur content in the form of organosulfides of greater than 0.5 moles (basis elemental sulfur) per kilogram of start-up feed.

Abstract: The melting point and the apparent degree of crystallinity of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon are stabilized against undue lowering during melt processing by inclusion within the polymer of an aluminum tri-alkoxide or hydrolysis product thereof.

Abstract: A method is disclosed for preparing a supported hydrogenation metal catalyst containing one each of Mo or W and of Co and/or Ni incorporated into a suitable support. An aqueous impregnating solution containing the desired quantity of catalytically active metals and having a pH in the range of about 0.7-2.7 is prepared containing (1) at least one each of a soluble compound of molybdenum or tungsten and a compound of cobalt and/or nickel; (2) a solubilizing amount of about 0.2-1.0 mole of phosphorous per mole Mo or W; and (3) about 2-6% w basis support, of a suitable soluble amine compound, such as amine alcohols, polyamines and amine acids. A suitable support, e.g., alumina, silica or silica-alumina, is then impregnated with the metals-containing solution. After impregnation the support is dried and calcined. This preparation method significantly increases the hydrodenitrification activity of the resulting catalyst in a hydrocarbon hydroconversion process.

Abstract: A process for homologating alcohols and/or acids to a mixture of higher acids by reaction with syngas in the presence of a ruthenium-rhodium-iodide-titanium(IV) catalyst.

Abstract: Hydroconversion catalysts containing Group VIII and/or Group VIB catalytically active metals on a support, and particularly those containing nickel and molybdenum on alumina, are improved in hydrodenitrification (HDN) activity by impregnation of additional molybdenum and/or tungsten carbonyls onto the catalyst by sublimation. Preferably from about 1 to 5% w molybdenum is added. The carbonyl impregnated catalyst is then dried, calcined and, generally sulfided before use in a hydrocarbon conversion process.
