the olefins polymerization process in a slurry reactor is discussed. the reaction rate dynamics was analyzed and the contributions of feed flow, gas-liquid mass transfer, polymerization reaction, and catalyst deactivation were estimated. the propylene solubility in a solvent mixture “heptane” was calculated using soave-redlich-kwong equation of state. these data were then approximated by henry-...

An efficient method was recently introduced by Thompson and Miller @J. Chem. Phys. 106, 142 ~1997!# for calculating thermal rate constants using the flux–flux autocorrelation function with absorbing boundary conditions. The method uses an iterative method to exploit the low rank feature of the Boltzmannized flux operator and subsequently only propagates the eigenvectors that have significant co...

The kinetics of the reaction hydroxyl radicals with HBr, important in atmospheric and combustion chemistry, has been studied a discharge flow reactor combined an electron impact ionization quadrupole mass spectrometer temperature range 235–960 K. rate constant OH + HBr ? H2O Br (1) was determined using both relative method (using Br2 as reference) absolute measurements, monitoring consumption u...
