The optimal control problem for the hydrogen evolution reaction (HER) system is posed for different cost objectives and admissible control strategies. The solution for the set-point-change process is given in analytical ...

The traditional approach in undergraduate chemical reaction engineering courses, as practiced in our uni-versity, is typically limited to design problems that can be solved by analytical methods. The study of single reaction ...

An optimization model is presented to determine optimal operating policies for tailoring high density polyethylene in a continuous polymerization process. Shaping the whole molecular weight distribution (MWD) by adopting ...

Biocatalysis is now a mature field, both in the laboratory and industrial scale. This approach counts on enzyme high selectivity, biodegradability, elegant control over the outcome of reaction conditions and as a possible ...

A method to simultaneously determine the chemical kinetics (kCT) and Langmuir’s adsorption equilibrium (KL) constants in porous catalyst particles where chemical reactions following Langmuir-Hinshel wood-Hougen-Watson ...

A bound state of a proton, p, and its counterpart antiproton, (Formula presented.), is a protonium atom (Formula presented.). The following three-charge-particle reaction: (Formula presented.)- is considered in this work, ...

The electrochemical splitting of water holds promise for the storage of energy produced intermittently by renewable energy sources. The evolution of hydrogen currently relies on the use of platinum as a catalyst—which is ...

An h-adaptive mesh procedure to solve the reaction-diffusion problem for multiple reactions in catalytic pellets presenting strong diffusion limitations is developed. The discretization approach selected for this purpose ...
