Abstract: A method for making catalyst materials is disclosed in which active metal ingredients of the final catalyst are added to a mixture for extruding the catalyst material that includes a binder, one or more precursors of one or more base metals and/or one or more noble metals, and a crystal of a zeolite. The extruded catalyst material is then pre-calcined and ion-exchanged and then a final calcining step is applied. The catalyst materials made by such a method are also disclosed as is a method for treating a hydrocarbon stream using the catalysts.

Abstract: This invention relates to reformer distillates as gassing additives for transformer oils. The reformer distillates have a 1-ring and 2-ring aromatics content of at least 98%, and are added such that the transformer oil contains less than 10 wt % of reformer distillate. The invention also relates to a method for preparing transformer oils containing reformer distillates and having excellent gassing tendency, oxidative stability, viscosity and volatility.

Abstract: In a catalytic dewaxing process, a catalyst comprising from 40 to 80 wt % of ZSM-48 having a silica to alumina molar ratio of less than 200:1 and from 0.3 to 1.5 wt % of a metal or metal compound from Groups 8 to 10 of the Periodic Table of the Elements is provided in a reaction zone. The catalyst is periodically contacted in the reaction zone under dewaxing conditions with a first hydrocarbon feedstock having a wax content of less than 50 wt % and with a second hydrocarbon feedstock having a wax content of 50 wt % or more.

Abstract: Supports for Fischer-Tropsch catalysts are formed by forming a particulate material from titania, alumina and optionally silica. A cobalt compound is incorporated into the particulate material which then is calcined to convert at least part of the alumina to cobalt aluminate.

Abstract: Small particle size catalysts having an average particle size of less than 20 or 10 microns, which agglomerate when contacted with a hydrocarbon liquid, are easily dispersed in the hydrocarbon liquid by first forming a mixture comprising the catalyst particles and one or more non-acidic, liquid polar oxygenates, such as an alcohol, ketone, ester, ether or mixture thereof. The mixture is contacted with the hydrocarbon liquid in which the particles then readily disperse. This process is useful for adding fresh or regenerated small particle size catalyst to catalytic hydroprocessing process slurries, including a reactive Fischer-Tropsch hydrocarbon synthesis slurry. One to four carbon atom alcohols are preferred oxygenates for use with a Fischer-Tropsch slurry.
