Abstract: Novel carbon molecular sieve (CMS) compositions comprising carbonized vinylidene chloride copolymer having micropores with an average micropore size ranging from 3.0 to 5.0. These materials offer capability in separations of gas mixtures including, for example, propane/propylene; nitrogen/methane; and ethane/ethylene. Such may be prepared by a process wherein vinylidene chloride copolymer beads, melt extruded film or fiber are pretreated to form a precursor that is finally carbonized at high temperature. Preselection or knowledge of precursor crystallinity and attained maximum pyrolysis temperature enables preselection or knowledge of a average micropore size, according to the equation ?=6.09+(0.0275×C)?(0.00233×T), wherein ? is the average micropore size in Angstroms, C is the crystallinity percentage and T is the attained maximum pyrolysis temperature in degrees Celsius, provided that crystallinity percentage ranges from 25 to 75 and temperature in degrees Celsius ranges from 800 to 1700.

Abstract: A method of controlling an engine system equipped with a supercharger may include determining a target value of boost pressure, depending on an rpm of an engine and then determining whether the supercharger is in an operable region, deducing a target rpm of the supercharger, based on a reference value previously input into the controller and a current state value of a vehicle input into the controller, when it has been determined in the operating-region determination that the supercharger is in the operable region, setting a maximum value, in the target rpm deduced in the target-rpm deduction, to a drive rpm of the supercharger, and verifying whether the set drive rpm is greater than or equal to a predetermined reference value previously input into the controller, and driving the supercharger at the set drive rpm, by closing the bypass valve to open the supercharger path.

Abstract: Porous composites of mullite and cordierite are formed by firing an acicular mullite body in the presence of a magnesium source and a silicon source. In some variations of the process, the magnesium and silicon sources are present when the acicular mullite body is formed. In other variations, the magnesium source and the silicon source are applied to a previously-formed acicular mullite body. Surprisingly, the composites have coefficients of linear thermal expansion that are intermediate to those of mullite and cordierite alone, and have higher fracture strengths than cordierite at a similar porosity. Some of the cordierite forms at grain boundaries and/or points of intersection between mullite needles, rather than merely coating the needles. The presence of magnesium and silicon sources during acicular mullite formation does not significantly affect the ability to produce a highly porous network of mullite needles.

Abstract: Skins and/or adhesive layers are formed on a porous ceramic honeycomb by applying a layer of a cement composition to a surface of the honeycomb and firing the cement composition. The cement composition contains inorganic filler particles, a carrier fluid and a clay material rather than the colloidal alumina and/or silica materials that are conventionally used in such cements. The cement compositions resist permeation into the porous walls of the ceramic honeycomb. As a result, lower temperature gradients are seen in the honeycomb structure during rapid temperature changes, which results in an increased thermal shock resistance.
