Reaction & Catalysis
Reactions and Catalysis are the fundamental processes that underlie all chemical engineering. The reaction of individual molecules and the role that catalysts can play in controlling those reactions all play an integral part in the design of process controls and other chemical systems.
Dr. Steven Kuznicki, a world authority on molecular sieves, recently published new findings with important implications for the purification of multiple classes of compounds, including light hydrocarbons and permanent gases. By substituting various halogen atoms bonded to titanium silicate sieves, the pore size of these sieves can be controlled absolutely, therefore changing the adsorptive qualities of the sieve.
