Knowra Chemical reaction engineering Chemical reaction engineering Chemical reaction engineering designs and analyzes reactors and reaction processes, connecting chemical kinetics and transport phenomena to the conversion of raw materials into products.
Chemical reactor : A vessel or system in which chemical reactions are carried out under controlled conditions. Reactor geometry and operating mode determine how reaction and transport shape conversion.
Material balance : An accounting equation that tracks the inflow, outflow, generation, and accumulation of matter. Material balances express how reactants and products change through a reactor.
Haber–Bosch process : An industrial process that synthesizes ammonia from nitrogen and hydrogen over an iron-based catalyst. Its high-pressure catalytic reactors illustrate how kinetics, equilibrium, and heat removal constrain production.
Batch reactor : A reactor in which reactants are charged, processed without continuous feed or withdrawal, and discharged after a run. Its time-varying operation contrasts with continuous-flow production.
Chemical kinetics : The study of how reaction rates depend on concentrations, temperature, and other conditions. Kinetic rate laws supply the reaction terms used in reactor models.
Energy balance : An accounting equation for energy entering, leaving, accumulating, and being generated or consumed. Energy balances capture reaction heat and determine temperature profiles.
Fluid catalytic cracking : A refinery process that converts heavy hydrocarbons into lighter products using circulating catalyst particles. Its reactor-regenerator system couples rapid chemistry with catalyst circulation and heat supply.
Continuous stirred-tank reactor : A continuously fed and withdrawn reactor modeled as perfectly mixed throughout its volume. Perfect mixing gives a distinct conversion pattern from plug-flow operation.
Residence time distribution : A description of the spread of times fluid elements spend inside a flow system. Nonideal residence times explain conversion differences from ideal reactor predictions.
Thermodynamics : The study of energy, heat, work, and the equilibrium states of physical systems. Thermodynamics sets feasible conversion limits and equilibrium compositions.
