Abstract: A process for the heterogeneous synthesis of chemical compounds such as methanol and ammonia through catalytic conversion of the respective gaseous reactants that are made to pass through a first (2) and a second (3) reaction zone connected in series with each other, in which they react in pseudoisothermal conditions, distinguishes itself in that in the first reaction zone (2) the gaseous reactants are made to flow through a fixed mass of an appropriate catalyst in which a plurality of substantially box-like, plate-shaped heat exchangers (21), arranged side-by-side and crossed by a heat exchange operating fluid, is dipped.

Abstract: A process is provided for stabilizing a petroleum liquid feed stream which contains a more volatile hydrocarbon portion, a less volatile hydrocarbon portion and water. The more volatile hydrocarbon portion of the petroleum liquid feed stream is reacted with the water in a fluidized bed heat exchanger to form a solid hydrate and a petroleum liquid product which contains the remaining less volatile hydrocarbon portion of the petroleum liquid feed stream. The petroleum liquid product is separated from the solid hydrate to recover the resulting petroleum liquid product which is substantially less volatile and more stable than the petroleum liquid feed stream and more suitable for storage or transport, particularly at low pressures.

Abstract: A shell-and-tube type heat exchanger of the smallest possible length necessary for heat exchange is disclosed which is capable of obtaining uniform distribution of flow of a shell side fluid and substantially eliminating the structural restriction imposed on the shell side. This shell-and-tube type heat exchanger is provided with one annular conduit furnished with not less than two partitions concurrently serving as an expansion joint for introducing and discharging a shell side fluid and allowing the flow path for said shell side fluid to be separated into an introducing part and a discharging part and which comprises a place having no array of heat-transfer tubes in the flow path for said shell side fluid. It prevents the equipment from necessitating an unnecessary enlargement due to the structural restriction on the shell side and enables the shell side fluid to produce a uniform flow.

Abstract: Processes are disclosed for the vapor phase polymerization of gaseous monomers, particularly olefins such as propylene and ethylene. A gaseous stream containing at least one gaseous monomer is passed upwardly through a series of fluidized bed reaction zones of successively smaller diameter. A polymerization catalyst is introduced into an uppermost one of said zones. The gaseous monomer is polymerized to form solid polymer particles which are a part of a fluidized bed in each zone, and which flow downwardly through the series of reaction zones, thereby decreasing a volumetric flow rate of the upwardly flowing gaseous stream as the stream moves upward. A velocity of the upwardly flowing gaseous stream is maintained at a sufficient level to fluidize the fluidized bed in each successive zone at least partially by means of the smaller diameter of each successive zone. Techniques are disclosed for dividing zones into subzones thus multiplying the effective number of stages of the reactor.

Abstract: A catalyst bed for conducting exothermal reactions between gases and/or other fluids is disclosed. The catalyst bed includes at least two cooling elements arranged in parallel relationship with each other. A space is thereby defined between the two cooling elements, and one opening at each opposite end of the cooling elements is also defined by the arrangement of cooling elements. The space created is adapted to receive a catalyst mass through either of the openings. The cooling elements cool the gases and/or other fluids, as well as the catalyst mass to keep the reaction temperature low enough to maintain a desired state of equilibrium.

Abstract: A multitubular catalytic reactor for exothermal catalytic reactions comprises a bundle of parallel tubes all of the same length and a catalyst within the tubes. The tube bundle has an inlet side and an outlet side. Devices are provided for introducing separately reactants to within the tubes of the reactor and coolant to the channels defined between adjacent tubes of the bundle. The coolant is introduced into the channels co-currently with the direction of flow of the reactants. The products are withdrawn from the tubes independently of the coolant. The reactor is particularly adapted to a single stage conversion of methanol into gasoline boiling point range constituents using crystalline aluminosilicate catalysts.
