Batch reactor - Wikipedia

The batch reactor is the generic term for a type of vessel widely used in the process industries.Its name is something of a misnomer since vessels of this type are used for a variety of process operations such as solids dissolution, product mixing, chemical reactions, batch distillation, crystallization, liquid/liquid extraction and polymerization.In some cases, they are not referred to as .

Molten salt reactor - Wikipedia

Molten salt reactor - Wikipedia

A molten salt reactor (MSR) is a class of nuclear fission reactor in which the primary nuclear reactor coolant and/or the fuel is a molten salt mixture. Key characteristics are operation at or close to atmospheric pressure, rather than the 75-150 times atmospheric pressure of typical light-water reactors (LWR), hence reducing the large, expensive containment structures used for LWRs and .

Using a fluidized bed reactor (Fig. 6.3) resolves some of the problems faced with a fixed bed reactor.This particular reactor offers a much more enhanced mass and heat transfer and minimizes temperature gradients throughout the reactor [64].The mass and heat transfer are improved due to better mixing of the catalyst with the fluid, which provides a greater surface area for the reaction to occur.
