A reactor apparatus and method useful in regulating temperature in a heterogeneous reaction system is provided. The apparatus includes an elongated tube reactor packed with a bed of solid particles through which a reactant fluid phase is passed. A plurality of heat transfer medium passage tubes are disposed in the bed of solid particles with adjacent tubes spaced relative to each other about the longitudinal axis of the reactor and with the tubes being substantially transverse to reactant flow through the reactor. The temperature in the system may, in turn, be regulated by effecting flow of a heat transfer medium through the passage tubes.

Temperature regulating reactor apparatus and method

A method for converting a lower molecular weight alkane to synthesis gas to higher molecular weight materials in the presence of a Fischer-Tropsch catalyst is disclosed.

Conversion of a lower alkane

A method for converting a lower molecular weight alkane to synthesis gas to higher molecular weight materials comprising (a) passing a reaction mixture comprising the alkane and air at a pressure of from about 1 to about 50 pounds per square inch gauge through an elongated first reactor packed with a bed of refractory particles having three zones: (1) an upstream zone for heating the mixture, (2) a middle zone wherein alkane and oxygen react exothermically to produce hot CO, H.sub.2, and N.sub.2 and (3) a downstream zone for cooling the hot CO, H.sub.2, and N.sub.2 ; and (b) passing cooled CO, H.sub.2, and N.sub.2 to a reactor packed with Fischer-Tropsch catalyst to form higher molecular weight materials.

A method and apparatus is disclosed for feeding solid materials against high pressures wherein a compressible solid is continuously conveyed through a screw extruder having a design compression ratio of from about 50 to about 100 percent of the compression ratio of the solid material being conveyed.

Method and apparatus for continuous pumping of compressible solids

Compositions of amorphous polyamides which are thermoplastic and characterized by an improved impact resistance which comprise terephthalamide and/or isophthalamide polymers, physically blended with polyolefin polymers.

Polyamide-polyolefin compositions

Vessel internals comprising at least one novel perforated, baffle-impellor combination attached to rotatable drive shaft are disclosed for use in a stirred, horizontal vessel containing solid particulate matter. Using such internals, dense masses present in such particulate can be efficiently concentrated towards one end of said vessel while maintaining in-place mixing of the particulate matter.
