Abstract: A system for preparing a dry process material includes a sealed container that holds and seals the dry process material therein and prevents airborne dust or particles from the dry process material from escaping the sealed container. Sealed processing equipment receives the dry process material from the sealed container and prevents the airborne dust or particles from escaping the sealed processing equipment. A sealed connection sealingly couples the sealed container to the sealed processing equipment and prevents the airborne dust or particles from escaping while transferring the dry process material. A sealed transfer conduit is sealingly coupled to and extends from the sealed processing equipment.

Abstract: A process for the remediation of contaminated particulate materials by the addition of an environmentally benign, carbonaceous fuel source in low concentration to enable or enhance smoldering combustion. The process may be applied to both in situ and ex situ treatments. In an ex situ smoldering process for the remediation of contaminated particulate materials in a continuous manner, contaminated feed is introduced near the top of a treatment unit and treated product emerges near the bottom. A smoldering front is maintained in the unit, fed by the fuel in the contaminated particulate material and a supply of combustion-supporting gas, such as air.

Abstract: A lubricant composition contains a lubricant base oil, (A) a detergent containing magnesium, (B) a compound containing boron, and (C) a zinc dialkyl dithiophosphate. The amount of component (A) is in the range of 200 to 1200 mass ppm [Mg] based on the mass of the lubricant composition, and the amount of component (C) is in the range of 300 to 1000 mass ppm [P] based on the mass of the lubricant composition. Component (C) includes a zinc dialkyl dithiophosphate having a primary alkyl group or a secondary alkyl group; the lubricant composition includes zinc dialkyl dithiophosphate having a secondary alkyl group; the mass ratio of the zinc dialkyl dithiophosphate having a primary alkyl group and the zinc dialkyl dithiophosphate having a secondary alkyl group is from 70:30 to 0:100; and the concentration of [B] is from 100 to 300 mass ppm based on the mass of the lubricant composition.

Abstract: In various aspects, systems and methods are provided for operating a molten carbonate fuel cell, such as a fuel cell assembly, with increased production of syngas while also reducing or minimizing the amount of CO2 exiting the fuel cell in the cathode exhaust stream. This can allow for improved efficiency of syngas production while also generating electrical power.

Abstract: Grease compositions are provided that can have one or more unexpectedly beneficial low temperature properties even though the grease compositions are formed from lower value components that traditional low temperature greases. The unexpectedly beneficial low temperature properties can be achieved in part by grease compositions that include a naphthenic base stock having a viscosity index of roughly 120 or less and/or a pour point of −20° C. or more while having a naphthenes content of 60 wt % or more. In some aspects, the naphthenic base stock can have an aromatics content of 20 wt % or less.

Abstract: Systems and methods are provided for integrating a chemical looping combustion system with molten carbonate fuel cells to provide improved operation of the molten carbonate fuel cells when using the exhaust from a gas turbine or other electrical power generation device as the CO2 source for the MCFC cathodes. This integration can be accomplished by using metal oxide in the chemical looping combustion system to oxidize the anode output flow from the MCFCs. This can reduce or minimize the number of separations that need to be performed in order to process the concentrated CO2 present within the anode exhaust. By reducing, minimizing, or eliminating the CO and H2 in the anode exhaust, the need to perform more costly separations (such as cryogenic separation or amine washing) to obtain a high purity CO2 product stream can be reduced or minimized. Optionally, the cathode exhaust from the molten carbonate fuel cells can be used as an oxygen-containing stream for regeneration of the metal oxide.

Abstract: Provided is a lubricating oil composition and method of using such a composition that provides for improved high temperature deposit resistance. The composition includes a lubricating oil base stock at from 20 to 95 wt % of the composition, at least one ashless organic friction modifier at from 0.1 to 20 wt % of the composition, and at least one overbased detergent at from 0.1 to 20 wt % of the composition. The remainder of composition includes one or more other lubricating oil additives. The deposit resistance of the lubricating oil composition as measured by TEOST 33C total deposits is at least 20% lower than the deposit resistance for a comparable lubricating oil composition not including the combination of the at least one ashless organic friction modifier and the at least one overbased detergent.
