Counter-Current Fluidized Bed Reactor for the Dehydrogenation of Olefins

A process and apparatus for the dehydrogenation of paraffins is presented. The process utilizes a reactor that includes a slower flow of catalyst through the reactor, with a counter current flow of gas through the catalyst bed. The catalyst is regenerated and distributed over the top of the catalyst bed, and travels through the bed with the aid of reactor internals to limit backmixing of the catalyst.

Method of removing heat from polymerization reactions of monomers in the gas phase

An improved method of removing heat from polymerization reactions of normally gaseous monomers in the gas phase comprising feeding the monomer in liquid form to a polymerization zone, immediately after entering said zone, removing a portion of said gaseous monomer from the polymerization zone, liquefying said portion of monomer by cooling it at the same pressure as that prevailing in the polymerization zone, recycling the liquefied monomer to the polymerization zone together with fresh monomer in liquid form and causing said liquid monomer to change to the gaseous form immediately after entering said zone. The improvement consists in not only condensing the monomer outside the polymerization zone but also storing the same, in keeping the temperature in the polymerization zone constant by regulating the rate at which liquid monomer is fed to the zone, and in keeping the temperature and pressure in the polymerization zone within limits conducive to the gaseous state of the monomer.

Production of olefin derivatives

Disclosed is a system of making an olefin derivative from a dilute olefin feed. Dilute olefin is sent to an olefin reaction unit to form an olefin derivative product. The olefin derivative product is recovered from the reaction unit while a vent stream is also removed. Olefin is separated from the vent stream, and the olefin is sent to the olefin reaction unit for additional processing.

Chlorinated residues containing 1 to 4 carbon atoms obtained in the production of chlorinated aliphatic hydrocarbons are vaporized and further chlorinated by introduction into a fluidized bed of particulate material and reaction with chlorine at 250‹ to 700‹ C., with simultaneous introduction into the fluidized bed at a controlled rate of at least one aliphatic hydrocarbon or additional chlorinated aliphatic hydrocarbon which reacts exothermically with chlorine, thereby controlling the temperature of the fluidized bed. The additional reactants specified are monochloroethane, 1,2-dichloroethane, chloroform and 1,2,2-trichloroethane. The fluidizing gas may be the chlorine, optionally diluted with hydrogen chloride or nitrogen, or may be air, nitrogen, carbon dioxide, hydrogen, hydrogen chloride or a vaporized organic compound, e.g. perchloroethylene. The vaporized chlorinated residues may be partly reacted and the exit gases then led to a further reactor, in which case the fluidizing gas may act as a diluent for the later reaction. The fluidized bed may also act as a heat-exchange medium or catalyst, and may be sand, alumina, microspheroidal silica, glass, metals, metal carbides, silicon carbide, hard dense carbons, or chlorination catalysts supported on talc, kieselguhr, carbon, silica or alumina. Feedstocks specified are residues from the production of vinyl chloride, trichloroethylene and perchloroethylene. Examples describe the chlorination of (a) a residue from the manufacture of trichloroethylene consisting of perchloroethylene, tetrachloroethane, pentachloroethane, hexachloroethane, tetrachlorobutadiene, pentachlorobutadiene and hexachlorobutadiene; and (b) a residue from the manufacture of perchloroethylene comprising trichloroethylene, perchloroethylene, tetrachloroethane, hexachloroethane, tetrachlorobutadiene ...

Process for producing cellulose carbamate

The present invention relates to a process for producing cellulose carbamate (CCA). A mixture of cellulose, liquid and urea is subjected to drying and heating to complete the carbamation reaction between cellulose and urea to produce cellulose carbamate and released ammonia in a fluidized bed. The mixture is introduced into a fluidized bed drying chamber; a stream of hot gaseous medium is introduced into the chamber to effect fluidization of the mixture in order to dry and heat the mixture, whereafter a stream of gaseous medium containing ammonia and the produced cellulose carbamate are removed from the fluidized bed drying chamber.

Plastics pyrolysis process with quench

A plastic catalytic pyrolysis process that can produce high yields of ethylene, propylene and other light olefins from waste plastics is disclosed. The catalytic product stream is quenched to below catalytic pyrolysis temperature quickly after exiting the reactor or bulk separation from the catalyst. Quench preserves selectivity of light olefinic monomers. The catalytic pyrolysis process can be operated in a single stage or a two-stage process.
