Catalyst composition dewaxing of lubricating oils

Abstract: Hydrocarbon lubricating oil feedstocks are dewaxed by passing the waxy feedstock over a catalyst bed containing a mixture of medium pore zeolite and large pore zeolite catalysts havig a Constraint Index less than 2 and having hydroisomerization activity in the presence of a hydrogenation component.

Multistage process for converting oxygenates to liquid hydrocarbons with aliphatic recycle

Abstract: A process for converting oxygenated feedstock, such as methanol, dimethyl ether or the like, to liquid hydrocarbons. In the primary catalyst stage the feedstock is contacted with zeolite catalyst to produce C2 -C4 olefins and C5 + hydrocarbons. In a secondary catalytic stage with oligomerization catalyst comprising medium-pore shape selective acidic zeolite at increased pressure converts C3 + olefins to gasoline and/or distillate liquids. The improvement is a technique for recovering lower alkene for recycle to the primary catalytic stage.

Foam Flow Through an Oil-Wet Porous Medium: A Laboratory Study

Abstract: A laboratory study of the steady generation and flow of gas and surfactant solution through an oil-wet porous medium indicates that foam is formed and is effective in reducing gas permeability. A comparison of the flow characteristics of foam in oil-wet and water-wet media showed that at similar surfactant concentrations gas permeability reduction in both systems is approximately equal. The ability to form stable foam in situ in an oil-wet porous medium appears to result from the alteration of the initially hydrophobic surface to hydrophilic by two mechanisms : surface tension reduction and surfactant adsorption. Wettability alteration of the hydrophobic surface is evidenced by a dramatic shift in liquid relative permeability when surfactant is present in the equeous phase

Metallized composite film structure and method

Abstract: A metallized film combination of an oriented polymeric substrate layer having on one surface thereof a coating of a blend of (a) a vinyl alcohol homopolymer or copolymer and (b) an ethylene-acrylic acid copolymer, the coating blend having a metal layer thereon. The method involves coating the substrate after the substrate has been machine direction oriented and before the combination is transverse direction oriented followed by TD orientation and finally by depositing a metal layer on the blend surface.
