Abstract: An apparatus for converting at least one nitrogen oxide, such as NO, O2, or N2O converts oxide in the presence of a catalyst supported on a metal mesh-like structure. The mesh-like structure is preferably fibrous formed of metal or ceramic fibers which may include knitted wire, sintered metal fibers and so on and has a porosity greater than about 85%. The mesh is formed into channels, preferably corrugations, and includes vortex generators, which generate turbulence to create a pressure differential across the mesh, to promote flow of fluids through the mesh pores which normally do not exhibit flow therethrough in the absence of such pressure differential. Preferred embodiments of structured packing and monoliths are disclosed each having a catalyst preferably in the mesh pores and/or coated on the fibers for converting the nitrogen oxide.

Abstract: A process for oxidizing environmentally harmful compounds which participate in atmospheric photochemical reactions to produce for example ozone and undesirable smog constituents from a fluid, in particular a gas, volatile organic compounds (VOC) including hydrocarbons, CO and any other constituent that participates in atmospheric photochemical reactions to produce for example ozone or smog constituents and combustible compounds to be removed from a gas stream for reasons of toxicity, photochemical reactivity or physical discomfort such as irritants, particulates, odor sources and so on, and compounds which may cause upper atmosphere ozone depletion or lower atmosphere ozone formation. The uncoated randomly oriented mesh-like structure preferably has a porosity greater than about 85%. The coated randomly oriented mesh-like structure preferably has a porosity greater than about 65%.

Abstract: A process for selectively oxidizing an organic molecule by reacting said organic molecule and oxygen in the presence of a selective oxidation catalyst supported on a mesh-like structure.

Abstract: A process of selectively hydrogenating an impurity in a feed containing hydrocarbons, such as, for example, an impurity selected from the group consisting of acetylene compounds, dienes, and mixtures thereof in a feed containing at least one monoolefin and the impurity wherein the impurity is hydrogenated selectively in the presence of a selective hydrogenation catalyst supported on a particulate support. The supported catalyst is supported on a mesh-like structure.

Abstract: In the production of methyl tert.-alkyl ethers by the reaction of methanol with isoalkylenes, the formation of dimethyl ether as an undesirable reaction by-product is reduced by recycling dimethyl ether to the reactor, advantageously in amounts sufficient to establish an equilibrium between the amount of dimethyl ether imparted to the reactor by way of recycle and the amount of dimethyl ether leaving the reactor as a portion of the reaction product whereby the formation of dimethyl ether in the reactor is essentially nil. In the present invention the essential recycle of dimethyl ether is accomplished by providing an adsorption capacity for dimethyl ether in the adsorption unit for recovering unreacted methanol and recycling dimethyl ether in combination with recycled methanol to the reactor as an effluent from the methanol adsorption unit during regeneration with isobutylene-containing C.sub.4 hydrocarbon feedstock.

Abstract: Low concentrations of methanol and dimethyl ether in distillation column C.sub.4 -C.sub.5 raffinate produced in the formation of methyl tert.-alkyl ethers by the reaction of methanol with isoalkylenes are effectively removed from the residual C.sub.4 -C.sub.5 hydrocarbons by adsorption on a dual or compound adsorption bed containing silica gel as the methanol adsorbent and zeolite 13X as the dimethyl ether adsorbent.
