Process Flow Diagram - Feedstock Recycling - Alberto Noto .

The reactor type in the pyrolysis or/and catalytic cracking process is generally constant stirred tank reactor (CSTR) and plug flow reactor. The problem is the fact that carbon residues tend to foul the walls of the reactor and thus give poor heat transfer from the external wall to the center of the reactor.

Chemical reactors - Essential Chemical Industry

A CSTR reactor is used, for example in the production of the amide intermediate formed in the process to produce methyl 2-methylpropenoate. Sulfuric acid and 2-hydroxy-2-methylpropanonitrile are fed into the tank at a temperature of 400 K. The heat generated by the reaction is removed by cooling water fed through coils and the residence time is .

Fluidized bed reactor - Wikipedia

A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst possibly shaped as tiny spheres) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.

The reactor under consideration for design is the auger screw reactor. For this project, it will specifically function as a Continuous Stirred Tank Reactor (CSTR). 17 Heat transfer is a major consideration in the design of a reactor to initiate pyrolysis. The diagram below illustrates how heat is transported to the fuel particle during pyrolysis:

The reactor was constituted by a sphere (D = 58 mm), into which the gas was injected in four different directions from nozzles (d=300 m) disposed as shown in Figure 1. This reactor is mainly used for combustion and pyrolysis gas reactions but its hydrodynamic has been studied at room temperature and atmospheric pressure.

Process Reactors Selection Guide | Engineering360

Types of Continuous Process reactors are Continuous Stirred Tank Reactor (CSTR), Plug Flow Reactor, Tubular Flow Reactor. CSTR : a vessel to which reactants are added and products removed while the contents within the vessel are vigorously stirred using internal agitation or by internally (or externally) recycling the contents.

Fluidised bed reactors

Enzyme Technology Fluidised bed reactors. These reactors generally behave in a manner intermediate between CSTRs and PBRs. They consist of a bed of immobilised enzyme which is fluidised by the rapid upwards flow of the substrate stream alone or in combination with a gas or secondary liquid stream, either of which may be inert or contain material relevant to the reaction.
