Abstract: A system is set forth for the exothermic generation of soot depleted syngas comprising (i) reacting a hydrocarbon-containing fuel with an oxygen containing gas in a first reactor to produce the syngas and byproducts comprising CO2, H2O and soot; and (ii) introducing the syngas and byproducts into a second reactor containing a non-carbonaceous material that traps the soot for a sufficient time such that the majority of the byproduct soot is gasified via reaction with the byproduct CO2 and/or H2O to produce a syngas stream that is depleted in the soot. The system is particularly suitable for the practice of heat exchange reforming wherein a portion of the heat is recovered from the soot depleted syngas stream and used as at least a portion of the heat to facilitate the additional production of syngas via the (endothermic) catalytic reforming of natural gas and steam.

Abstract: An engine includes a fuel injector support element to support a fuel injector and define a first opening through which the fuel injector can inject fuel. A first piston defines a substantially cylindrical inner chamber and a portal into the substantially cylindrical inner chamber. One or more second pistons are arranged to reciprocate inside the substantially cylindrical inner chamber and to define, in cooperation with the substantially cylindrical inner chamber, a combustion chamber. The first fuel injector support element and the first piston are arranged such that, during engine operation, the first piston reciprocates relative to the first fuel injector support element to thereby cause the first opening and the first portal to move in and out of alignment with one another.

Abstract: An unitary stratified composite composed of a first stratum and a second stratum integrally connected by a transition zone is disclosed. The first stratum serves as a liquid acquisition stratum that rapidly acquires and then transfers liquid to the second stratum. The second stratum serves to withdraw liquid from the first stratum and further severs as a temporary storage stratum. Methods for forming the unitary stratified composite are also disclosed.

Abstract: An absorbent composite (10) having a fibrous matrix that includes absorbent material is disclosed. The fibrous matrix defines voids (14) and passages between the voids, which are distributed throughout the composite. Absorbent material (18) is located within some of the voids (14). Absorbent material located in these voids is expandable into the void. In a preferred embodiment, the composite's fibrous matrix includes resilient and matrix fibers (16). The composite optionally includes a wet strength agent.
