Abstract: An imaging member having a charge transport layer with multiple regions or layers is provided. The charge transport layer includes at least two charge transport layers coated from solutions of different components and concentrations, wherein the second (top) transport layer comprises a lower concentration of different charge transport compound than the first (bottom) charge transport layer. The charge transport compound included in the second (top) charge transport layer is a high mobility hole transport compound. The charge transport compound in each layer is dissolved or molecularly dispersed in an electrically inactive film forming polymer to form a solid solution. In such a construction, the resulting dual charge transport layer exhibits enhanced cracking suppression, improves wear resistance, provides excellent imaging member electrical performance, and delivers improved print quality.

Abstract: An annular heat-exchange reactor vessel allows for selectively controlled heat transfer between a first fluid and second fluid flowing through the vessel. Optionally, catalyst means may be added to further convert either fluid into a desired end product. In this regard, it is envisioned that the present invention will have particular utility in fuel processing systems. Additional, in-line upstream or downstream annular modules may also be incorporated to create a more complete, efficient and/or compact system. Various methods for constructing this reactor system are also disclosed.

Abstract: A modular fuel processing system has component modules stacked together into a single tower or stacked separately in various configurations in other embodiments. A backbone member having all fluid connections for the modules thereon connects the component modules of the stack(s). The backbone member may contain quick disconnect fittings on each module. The modules of the system are preferably configured using plate-type reactors.

Abstract: A method and apparatus for producing clean, sweet, fuel gas for use in a combustion process and for producing other useful products by processing a waste stream from digestion of lignocellulosic material. Essentially, the waste stream is partially oxidized to form hot gases and molten salts. The hot gases and molten salts are then cooled using a quench liquor to form quenched gas and carbonate liquor. Particles are removed from the quenched gas to form a raw fuel gas, preferably by subjecting the quenched gas to a multi-step fume reduction process which includes heat extraction from the quenched gas to reduce particulate load and water content of the quenched gas to form a low fume fuel gas. H2S is removed from the low fume fuel gas using an H2S removal process which is more selective for H2S than it is for CO2, the removing step forming clean, sweet, fuel gas and acid gases.
