Abstract: A process wherein an FCCU off gas is treated by first subjecting the off gas to an alkylation with a heavy reformat to remove the propylene and contaminants after which the gas is separated from the reformat and alkylated products by distillation to produce an ethylene feed suitable for the reaction with benzene to produce ethyl benzene.

Abstract: A multi-purpose distillation column reactor is disclosed which may be used for the production of tertiary amyl methyl ether from the reaction of the isoamylenes contained in a light naphtha with methanol. Two reaction distillation zones are disposed above a stripping section. The stripping, in addition to removing the TAME product, also removes the C.sub.6 and heavier components. The first reaction distillation zone contains a hydrotreating catalyst for removing diolefins and mercaptans. The second distillation reaction zone contains an acid cation exchange resin for the etherification reaction and the entire column serves to fractionate the multiple component reaction system (reacts, inerts, products and contaminants) concurrently with the multiple reactions.

Abstract: A process is provided to remove oxygenates from a C.sub.4 raffinate stream from an MTBE plant. A back-cracking catalyst is placed into the bottom of an oxygenate removal column which will convert any MTBE or TBA contained therein back to their original components of isobutene and methanol or water. The raffinate stream is first subjected to a water wash to remove the gross amounts of methanol and DME.

Abstract: There is provided a new process for conducting heterogeneous chemical reactions in which a particulate catalyst is slurried in one of the reactant streams and fed into a distillation column reactor in a distillation reaction zone. The distillation reaction zone contains inert packing which provides the distillation structure for separation. The slurried catalyst trickles downward through the inert packing and is removed with the bottoms and separated therefrom for regeneration or replacement.

Abstract: Organic aromatic compounds are alkylated in a Reactive Distillation.TM. reactor, wherein the solid particulate catalyst is slurried in the aromatic feed stream and fed to a reaction zone containing inert distillation packing. Olefin is vaporized and fed to the bottom of the reaction zone and agitates the catalyst while reacting the olefin with the aromatic to form an alkylation product. The alkylation product is removed from the lower end of the reaction zone and recovered. Any unreacted aromatic is distilled overhead and recycled or recovered. Recycling the aromatic controls the molar ratio of aromatic to olefin to the extent that substantially all of the olefin is reacted.

Abstract: The present invention provides catalytic distillation structures which are useful in the concurrent reaction and distillation of a reaction mixture. The distillation structures are provided as rigid containers having a volume substantially smaller than the volume of conventional distillation column reactors. The catalyst component is loaded into the containers and the containers are closed. Openings are provided to allow vapor and liquid passage into and out of the containers. The surfaces of the containers provide the necessary/vapor liquid contact surfaces for the distillation. The rigidity of the containers provides for spacing the structures and the necessary free space for the distillation.

Abstract: A pipeline monitoring system for determining profile, ovality and displacement of oil, gas and products pipelines. The system comprises one or more pig carriers housing a plurality of sensors including a strapdown inertial measurement system, a secondary sonar measurement system, digital recorder, weld detector and odometer. The inertial measurement system detects primary acceleration and orientation data of the monitoring system within a pipeline and the secondary system generates redundant data for verifying the acceleration orientation information provided by the inertial system. The digital recorder records all of the information generated by the various measurement systems and sensors for post ash processing analysis to determine the aforementioned features of profile, ovality and displacement of pipelines.

Abstract: A process is provided for the skeletal isomerization of straight chain olefins to branched chain olefins by contact at an elevated temperature with a chlorine- or fluorine-containing compound activated alumina catalyst, the alumina having an average particle size of from about 0.5.times.10.sup.-3 cm to about 160.times.10.sup.-3 cm and from 3 to 9% of the pore volume being attributable to pores having radii from about 100 to about 10,000 Angstroms.

Abstract: A versatile, adjustable storage system for fishing rods which consists of two basic components. One component comprises an extruded storage rack adapted to be mounted on a vertical surface. The rack includes an upper L-shaped flange and a lower flange which has a dovetailed channel or slot formed longitudinally therein. The other component comprises a socket member consisting of an annulus having a rearwardly extending support which terminates in a dovetailed flange. The dovetailed flange of the socket member may be slidably inserted within the longitudinal dovetailed channel of the extrusion, and a plurality of such sockets may be fitted onto a single storage rack and may be of different or common sizes for storing any desired number or type of fishing rods.

Abstract: A holder assembly for a fishing rod or the like, including a number of readily replaceable elements adapted to hold any standard fishing rod during actual fishing, as in trolling, and safely store the rod while cruising to and from the fishing grounds, the assembly comprising a mounting base with keyhole connecting means for quickly attaching to or detaching from a supporting surface, a tubular socket on the base, an elongated sleeve for slidably receiving and holding a fishing rod handle, and means for readily securing and detaching the sleeve to and from said socket. The substitution of another sleeve having a portion with a larger diameter enables the holding of larger and heavier fishing rods. The substitution of another mounting base having a different angular arrangement of the tubular socket renders the holder assembly readily mountable on vertical, horizontal or angled supporting surfaces of a boat and permits the changing of the angular position of the held fishing rod.
