Diffusion and chemical reaction in isoamylene etherification within a cation-exchange resin

DIFFUSION AND REACTION WITHIN A SHAPED NICKEL PEROVSKITE CATALYST

  Abstract : In this study, we prepared a LaNi0.3Al0.7O3 perovskite catalyst using a sol-gel related method (with prop ionic acid as a solvent) for use in the methane dry reforming reaction to produce synthesis gas. We defined the catalyst structure on the basis of X-ray diffraction analysis and measurements of the specific surface area and particle size distribution. The mixed oxide structure ...

Carboxylic cation exchange resin effects in dogs.

Reports describing trials of exchange resins in removing cations from the gastrointestinal tract of experimental animals have been limited to toxicity studies and to measurements of the relative magnitudes of the oral intake and the stool output (1-3). In the experiments presented in this paper changes in serum, urine, and stool components, as well as the external and internal balances of certa...

A cation-exchange resin artificial kidney: development and metabolic studies.

are relatively few, and generally are related to either inadvertent transfusion of incompatible blood or the outcome of some severe form of injury. The latter may follow a surgical operation or be the result of massive trauma incurred during combat. The consequent renal insufficiency is often temporary in nature, and efforts are directed at prolongation of life by sustaining the patient through...

Kinetics of the Esterification Reaction between Pentanoic Acid and Methanol Catalyzed by Noncorrosive Cation Exchange Resin

The extensive demand for cleaner environment is forcing the chemical industry to use less hazardous materials. In this regard, solid catalysts have lately attracted the attention of scientists and researchers around the world.1–8 By using sufficient amounts of these heterogeneous catalysts, their catalytic activity for ester formation can be equivalent to that of conventional homogeneous cataly...
