An apparatus includes a conduit with two process fluid inlets at one end of the conduit, one process fluid outlet at an opposing end, a heat exchange medium inlet, and a heat exchange medium outlet. One of the fluid inlets includes a tube extending into the conduit and a perforated node at the end of the tube, and the other of the fluid inlets is arranged up stream of the perforated node. The apparatus further includes hollow tubes positioned longitudinally within the conduit between the two process fluid inlets, the process fluid outlet, the heat exchange medium inlet and the heat exchange medium outlet. In addition, the apparatus includes a collection vessel positioned proximate the fluid outlet and fibers extending through each of the hollow tubes, wherein one end of the fibers is secured to the perforated node and the other end of the fibers extends into the collection vessel.

A reactor and process for the production of bio-diesel. The reactor includes one or more coiled reaction lines. The lines are positioned within a tank containing a heat transfer media such as molten salt, maintained at about 750? F. A pump circulates the media within the tank. An emulsion of alcohol; refined feed stock, including glycerides and/or fatty acids; and preferably water is pumped through the reaction lines at temperatures and pressures sufficient to maintain the alcohol in a super-critical state. The curvature of the coils, pump pulsing, and the flow rate of the emulsion keep the emulsion in a turbulent state while in the reactor, ensuring thorough mixing of the alcohol and feed stock. The alcohol reacts with the glycerides and fatty acids to form bio-diesel. The reaction is fast, efficient with regard to energy input and waste generation, and requires minimal alcohol.

A method for producing biomass derived liquid, comprises: feeding biomass, a solvent and a catalyst into a batch reactor, and heating and mixing in the batch reactor a compound comprising the biomass, solvent, and catalyst. The solvent is glycerol and wherein feeding the solvent into the batch reactor is performed through electrostatic atomization.

The reactor has a heat exchanging body which includes therein a heat medium flow channel in which heat medium fluid is caused to flow, a reaction flow channel in which a reaction fluid containing a first reactant (and a second reactant) is caused to flow, and a supplement channel for supplying a second reactant at an intermediate portion of the reaction flow channel. A catalyst is provided in the reaction flow channel and promotes the reaction in the reaction fluid. The heat exchanging body has a plurality of holes through which the supplement channel communicates with the reaction flow channel. Steam reforming can be performed using water vapor and hydrocarbon as the first and second reactants.

This disclosure relates to a processing that includes a first shell and a second shell disposed within the first shell. The second shell includes a first end, a second end, and a wall extending between the first end and the second end. The second shell also defines a cavity and a longitudinal axis extending between the first end and the second end. A cross section of the second shell transverse to the longitudinal axis includes a first arcuate inner wall portion having a first radius of curvature and a second arcuate inner wall portion having a second radius of curvature. The first radius of curvature is larger than the second radius of curvature.

This disclosure describes an improved heat transfer system for use in reaction vessels used in chemical and biological processes. In one embodiment, a heat transfer baffle comprising two sub-assemblies adjoined to one another is provided.

The present invention relates to a tubular reactor (14) for multi-phase polymerization, in particular for producing butyl rubber, comprising a pipe piece (16) for radially delimiting a reactor volume between an inlet (18) and an outlet (20), a stirrer (22) for generating a flow (27) in the radial direction of the pipe piece (16), wherein the stirrer (22) is dimensioned and operable such that the flow (27) is impartable with a centrifugal force which generates a concentration distribution in the radial direction inside the pipe piece (16) and an outlet conduit (32) for discharging a concentrated radially inner part (30) of the flow (27, 28). Enrichment of polymer particles in the radially inner part (30) of the flow (27, 28) avoids gumming of the pipe piece (16) by the polymer particles so that the risk of a blockage is reduced.

A reactor includes a reaction unit, a first pipe, a second pipe, a composition analysis unit connected to the first pipe, a regulating unit connected to the second pipe so as to regulate a flow rate or the like of a second fluid, a control unit causing the regulating unit to regulate the flow rate or the like of the second fluid in accordance with a composition of a product analyzed by the composition analysis unit so that a temperature of a third fluid is controlled to lead the composition of the product to keep a predetermined reaction rate or yield, and a first temperature measurement unit connected to the first pipe so as to measure the temperature of the third fluid. The control unit acquires the information on the temperature of the third fluid from the first temperature measurement unit.

A continuous chemical reactor may include a primary reaction unit and at least one secondary reaction unit. The primary reaction unit has a stirring device and a first temperature regulating device, and a feed inlet provided at an upper portion thereof. The secondary reaction unit is sleeved outside the primary reaction unit, and a reaction chamber is formed therebetween. By adding reaction materials to the primary reaction unit via the feed inlet and adjusting the temperature of the reaction materials by the first temperature regulating device, the reacted materials enter the reaction chamber, and the heat generated in the reaction chamber can be used to adjust the temperature of the materials in the primary reaction unit to more effectively use the heat, and the product after reaction can be discharged from a discharge hole at the lower end of the secondary reaction unit, thereby achieving continuous production.
