Enzyme catalysis coupled with artificial membranes towards process intensification in biorefinery- a review

Perovskite membranes in ammonia oxidation: towards process intensification in nitric acid manufacture.

Ammonia is oxidized over PtRh alloy gauzes to form NO as the first step in the industrial production of nitric acid, a process that has remained practically unchanged for over 80 years. The reaction typically yields 94–96% NO and 4–6% by-products (N2O and N2) at 1073–1223 K. [1] Major drawbacks associated with the platinum-based catalysts are: 1) high production cost, 2) metal loss in the form ...

Book review MODELING OF PROCESS INTENSIFICATION

Network of coupled promoting motions in enzyme catalysis.

A network of coupled promoting motions in the enzyme dihydrofolate reductase is identified and characterized. The present identification is based on genomic analysis for sequence conservation, kinetic measurements of multiple mutations, and mixed quantum/classical molecular dynamics simulations of hydride transfer. The motions in this network span time scales of femtoseconds to milliseconds and...

A Review of Aerogel Applications in Adsorption and Catalysis

Aerogels are a special class of porous material, which have excellent physicochemical properties such as low density, high porosity, high surface area and adjustable surface chemistry. Aerogels were first prepared several decades ago, but never truly commercialized due to their high cost. Technological advancements in the production and quality of different types of aerogel cut costs down and m...

A Review of Membrane Technology for Integrated Forest Biorefinery

More recently, the concept of integrated forest biorefinery (IFBR) has received much attention as a promising solution for the struggling forest industry in North America and Europe to overcome its difficult financial period and competes globally. This new business paradigm offers a broad range of potentially attractive products, from bioenergy to value-added green organic chemicals in addition...
