Abstract: Various systems and methods are described that can be used as part of a process to separate bitumen from oil sands. The process may include adding a hydrocarbon solvent to a bitumen containing extract. The tailings from this process may contain a significant amount of solvent. The solvent may be recovered from the tailings with a tailings solvent recovery unit that utilizes negative pressure to significantly reduce the cost of the process in comparison to a conventional steam stripping unit. In one embodiment, the tailings may also separated prior to entering the tailings solvent recovery unit with a gravity separation apparatus or a cyclonic separation apparatus, such as a hydrocyclone.
Abstract: Methods of oxidative dehydrogenation are described. Surprisingly, Pd and Au alloys of Pt have been discovered to be superior for oxidative dehydrogenation in microchannels. Methods of forming these catalysts via an electroless plating methodology are also described. An apparatus design that minimizes heat transfer to the apparatus' exterior is also described.

Abstract: A method and apparatus for removing peroxides from an exposed naphtha stream is shown and described. The process includes the catalytic reactive oxygen stripping of peroxides thereby generating hydrocarbons and oxygen. Numerous conventional catalysts may be employed. The catalytic stripping reaction can be carried out at substantially lower temperatures than conventional reboiled oxygen strippers thereby resulting in substantial energy savings. Further, the disclosed reactor vessels are substantially smaller and less expensive to build than conventional oxygen stripper columns The disclosed energy efficient reactive oxygen stripping process and equipment is intended to be utilized upstream of a naphtha hydrotreating unit.

Abstract: A combination nano and microparticle treatment for engines enhances fuel efficiency and life duration and reduces exhaust emissions. The nanoparticles are chosen from a class of hard materials, preferably alumina, silica, ceria, titania, diamond, cubic boron nitride, and molybdenum oxide. The microparticles are chosen from a class of materials of layered structures, preferably graphite, hexagonal boron nitride, magnesium silicates (talc) and molybdenum disulphide. The nano-micro combination can be chosen from the same materials. This group of materials includes zinc oxide, copper oxide, molybdenum oxide, graphite, talc, and hexagonal boron nitride. The ratio of nano to micro in the proposed combination varies with the engine characteristics and driving conditions. A laser synthesis method can be used to disperse nanoparticles in engine oil or other compatible medium.
Abstract: Processes are described for producing liquid, biobased lubricant additives containing from 50 to 100% biobased carbon according to ASTM D6866 from heat-bodied oils by transesterification with biobased or petroleum based alcohols and by hydrogenation of at least the resulting diesters, triesters and polyesters.
Abstract: An improved fuel processor for fuel cells is provided whereby the startup time of the processor is less than sixty seconds and can be as low as 30 seconds, if not less. A rapid startup time is achieved by either igniting or allowing a small mixture of air and fuel to react over and warm up the catalyst of an autothermal reformer (ATR). The ATR then produces combustible gases to be subsequently oxidized on and simultaneously warm up water-gas shift zone catalysts. After normal operating temperature has been achieved, the proportion of air included with the fuel is greatly diminished.

Abstract: The present invention relates to a device and respective process for distribution of mixed charges comprising a flat tray in the form of a disc drained by a series of drainage tubes located above the surface of fixed beds of catalysts, capable of promoting the homogenisation and distribution of charges by means of said device. Such drainage tubes mounted in said manner have the objective of restricting and reorienting the flow of mixed charges, multiplying the points whereon they fall, principally of the liquid phase, onto said beds of catalysts. For the purpose of doing so said drainage ducts, being segments of tubes, distributed on the entire surface of said tray possess caps affixed at the upper extremity thereof impeding the direct flow of charge onto the bed of catalyst, creating a reservoir of liquid on the tray, subsequently being drained down such device in a more controlled manner.
