Abstract: Alkylaromatic compounds may be prepared by utilizing paraffinic hydrocarbon as an alkylating agent for the aromatic compound. The alkylation is effected in a fragmented scavenging reaction in which the paraffinic hydrocarbon acts as a fragment donor while the aromatic compound acts as a scavenging agent. The reaction is effected by decomposing a paraffinic hydrocarbon on the surface of a nonacid-acting catalyst at a temperature in the range of from about 50.degree. to about 400.degree. C. and a pressure in the range of from about 0.33 atmospheres to about 50 atmospheres.

Abstract: An electric lamp bulb or electric resistance coil is provided to radiate heat to one or more adjacent surfaces which have an active oxidation catalyst such that fumes and odors in the confines of a room that are drawn over the catalytic surface will be converted to less objectionable products. A catalytic device with an incandescent light bulb type of heating element is of particular advantage in that it can readily be screwed into a lamp base or mounted in other forms of current supplying receptacles and, in addition to a light source, will provide a heat emitting surface for heating the catalyst surface and inducing natural air convection current flow past the catalytic surface. Also, a fume control device which utilizes a resistance heating coil can readily provide both radiant heat and convection heat so that there will be the dual function of fume oxidation from air flow past a heated catalyst surface and radiant heat into a room area.

Abstract: Refractory inorganic oxide particles characterized by low bulk density in combination with high micropore volume are disclosed. The particles, especially the low bulk density - high micropore volume alumina particles, are useful as a support or carrier material to yield an improved reforming catalyst which is also disclosed.

Abstract: An electric lamp bulb type of heat furnishing unit is provided with a covering of active oxidation catalyst such that fumes and odors in the confines of a room that are drawn over the catalytic surface will be converted to less objectionable products. A light bulb type of catalyst supporting device is of particular advantage in that it can readily be screwed into a lamp base or other form of current supplying receptacle and, in addition, will provide a hot surface for inducing natural air convection current flow past the catalytic surface. Various types of coatings and/or catalytic wrappings may be used on the bulb to provide any particular type or form of catalytic surface.
