Adiabatic reactor: Vessel that is well insulated to minimize heat transfer and has an increase or decrease in temperature from the initial inlet conditions due solely to the heats of reaction. Batch reactor: Vessel used for chemical reaction that has no feed or effluent streams. The reactor is well stirred and usually run either isothermally or adiabatically. The main design variable is how much time the reactants are allowed to remain in the reactor to achieve the desired level of conversion. Catalyst: Substance that increases the rate of a chemical reaction without being consumed in the reaction. Continuous stirred tank reactor: Sometimes called a continuous-flow stirred-tank reactor, ideal mixer, or mixed-flow reactor, all describing reactors with continuous input and output of material. The outlet concentration is assumed to be the same as the concentration at any point in the reactor. Conversion: Fraction or percentage that describes the extent of a chemical reaction. Conversion is calculated by dividing the number of moles of a reactant that reacte
