The function of the Department of Chemical and Biological Engineering has been to prepare students for the study and application of chemistry in industry. This focus has included preparation for employment in various industries as well as the development, design, and operation of equipment and processes within industry.Through the CBE Department, Iowa State University is nationally recognized for its initiatives in bioinformatics, biomaterials, bioproducts, metabolic/tissue engineering, multiphase computational fluid dynamics, advanced polymeric materials and nanostructured materials.
History
The Department of Chemical Engineering was founded in 1913 under the Department of Physics and Illuminating Engineering. From 1915 to 1931 it was jointly administered by the Divisions of Industrial Science and Engineering, and from 1931 onward it has been under the Division/College of Engineering. In 1928 it merged with Mining Engineering, and from 1973–1979 it merged with Nuclear Engineering. It became Chemical and Biological Engineering in 2005.

Abstract
A series of metallic Re/C catalysts were prepared with the microwave-assisted thermolytic method by using decacarbonyldirhenium [Re2(CO)10] as a precursor for the hydrogenation of succinic acid. The results of FT-IR, UV-Vis, XRD, HRTEM, ICP, TPR and CO chemical adsorption showed that the as-prepared catalysts had well-dispersed rhenium nanoparticles on activated carbon. Changing irradiation time or rhenium loadings could effectively adjust the properties of Re/C catalysts which exhibited good catalytic performance for the hydrogenation of succinic acid. There were plenty of active sites on Re/C catalysts for the high concentration hydrogenation of succinic acid, and increasing temperature or pressure improved catalytic activity at a defined scope. From the kinetic study of succinic acid catalytic hydrogenation, there was a certain converting relationship between the different intermediates and the product distribution which could be controlled by variation of reaction time.
