A batch reactor may be described as a vessel in which chemicals are placed to react. Batch reactors are normally used in small-scale laboratory set-ups to study the kinetics of chemical reactions. To determine the order and constant of a chemical reaction, the variation of a property of the reaction mixture is observed as the reaction progresses.

Heterogeneous Reaction Definition - ThoughtCo

The reaction between acid and metal is a heterogeneous reaction. A reaction between a gas and a liquid, as between air and seawater, is heterogeneous. A reaction at the surface of a catalyst is heterogeneous. In contrast, a reaction between two miscible liquids or between two gases is homogeneous.

a nuclear reactor in which the active core consists of a homogeneous mixture of nuclear fuel and a moderator. The distinguishing feature of the homogeneous reactor is the absence of fuel elements; the nuclear fuel and the raw material for breeding (uranium, thorium, or plutonium) may be placed into the active core as a salt solution with ordinary or heavy water, or as a dispersion in a solid .

Synthesis of Optimal Chemical Reactor Networks .

The reactor is the most influential unit operation in many chemical processes. Reaction systems and reactor design often determine the character of the flowsheet. However, research in reactor network synthesis has met with limited success because of nonlinear reaction models, uncertain rate laws, and numerous possible reactor types and networks. In this paper we take advantage of attainable .

Aqueous homogeneous reactor - Wikipedia

Aqueous homogeneous reactors (AHR) are a type of nuclear reactor in which soluble nuclear salts (usually uranium sulfate or uranium nitrate) are dissolved in water. The fuel is mixed with the coolant and the moderator, thus the name "homogeneous" ("of the same physical state") The water can be either heavy water or ordinary (light) water, both of which need to be very pure.

Elements of Chemical Reaction Engineering

Most homogeneous liquid-phase flow reactors are CSTRs, whereas most homogeneous gas-phase flow reactors are tubular. The costs of PFRs and PBRs (without catalyst) are similar to the costs of heat exchangers and can be found in Plant Design and Economics for Chemical Engineers, 5th ed., by M. S. Peters and K. D.

1. Introduction. In a chemical reactor carrying out the exothermic reaction, when the rate of heat generation by chemical reaction exceeds the rate of heat removal by cooling, the reaction accelerates and, if no countermeasures are taken, the loss of temperature control (thermal runaway) may occur.The most important part of each early warning detection system is a proper and robust criterion .

Homogeneous and Heterogeneous Reactors - Nuclear Energy

One variant of this reactor type was known as the aqueous homogenous reactor because the fuel was mixed with water (H2O or D2O). In the so-called homogeneous reactor experiment, two small reactors, called HRE-1 and HRE-2, were built at Oak Ridge National Laboratory (ORNL) in the 1950s.1 For HRE-2, the fluid was uranyl sulfate (UO2SO4) in heavy .
