Chemical reaction engineering

technology Maturity 9-11 Next article →

Chemical reaction engineering is a specialized branch of chemical engineering and industrial chemistry. It focuses primarily on the study and design of chemical reactors. A reactor is a device or a system where chemical changes occur. This field is essential because it helps scientists optimize how reactions happen. By doing this, engineers can define the most efficient reactor designs possible. This work is vital for creating new industrial processes and improving existing technologies.

To design a great reactor, engineers must understand several complex interactions. They study reaction kinetics, which is the study of how fast a chemical change occurs. They also look at mass transfer, which is how substances move through a system. Heat transfer is another critical factor because reactions often create or require temperature changes. Engineers must also consider flow phenomena, or how liquids and gases move through the reactor. Finally, they study how the composition of the feed affects the final result. All these factors work together to determine how well a reactor performs.

Reactors can take many different forms depending on the job they must do. Some systems use a catalyst to help the chemical reaction proceed. A catalyst is a substance that assists a reaction without being consumed itself. These catalysts can be homogeneous, meaning they are in the same phase as the reactants. They can also be heterogeneous, meaning they are in a different phase. Sometimes, a reactor is not a single standalone machine. It might be integrated into a larger process. Examples include reactive separation vessels, retorts, certain types of fuel cells, or even photocatalytic surfaces.

The history of this discipline began in the early 1950s. It grew from the work of researchers at the University of Delft. Scientists at the Shell Amsterdam research center also helped drive this progress. The specific term "chemical reaction engineering" was likely created by J.C. Vlugter. He used the term while preparing for a major event in 1957. This event was the 1st European Symposium on Chemical Reaction Engineering held in Amsterdam. Since then, the field has grown from a niche study into a global science.

Professional researchers share their findings at the International Symposia on Chemical Reaction Engineering, known as ISCRE. These are important three-day conferences that happen every two years. The meetings follow a six-year cycle that rotates through North America, Europe, and the Asia-Pacific region. These gatherings bring together distinguished researchers, industrial experts, and new students. They provide a place to discuss the current state of the art in the field. They also allow researchers to explore new frontiers and consolidate their gains.

The ISCRE Board recognizes excellence through two major awards given every three years. The Neal R. Amundson Award honors pioneers who have greatly influenced the field. This award was established in 1996 and is supported by the ExxonMobil Corporation. It includes a plaque and a $5,000 check. Winners have included famous professors like Neal Amundson and Octave Levenspiel. The second honor is the Rutherford Aris Young Investigator Award. This award recognizes researchers in the early stages of their careers. To qualify, the recipient must be under 40 years old at the end of the year. This award includes a plaque, a $3,000 honorarium, and up to $2,000 for travel.

While this science was originally used for the petroleum and petrochemical industries, its reach is much wider. The methodology combines reaction chemistry with chemical engineering concepts. This allows engineers to optimize many different types of systems. It is used whenever a process requires the modeling or engineering of chemical reactions. This makes it a fundamental part of modern industrial chemistry. By mastering these reactions, we can create more efficient ways to power our world and build new materials.
