Applying Nonlinear Regression to Kinetics of Hexane Isomerization

Hexane Isomerization over a Zeolite Catalyst

“…The results indicate an order of ease of conversion of 2,3-DMB > 2-MP > 3-MP > n-Ce > 2,2-DMB. Other researchers, using various catalysts, have reported different orders of ease of conversion (Ciapetta and Hunter, 1953; Cull and Brenner, 1961;Evering and Waugh, 1951). By summarizing the data from the various catalysts, an order of ease of conversion for four of the isomers is found to be 3-MP > 2-MP > n-C6 > 2,2-DMP.…”

Kinetics of Simultaneous Isomerization and Cracking of the Five Hexane Isomers by Use of the Wei-Prater Method

“…A similar scheme was used by Cull and Brenner (1961) for evaluation of eight rate constants from five simultaneous ordinary differential equations, by which the reaction system was described. Beecher and Voorhies (1969) based their calculations of conversion vs. reaction time data for hexane isomerization on a zeolite catalyst upon a simple reversible three-component system-n-hexane, 2,2-dimethylbutane, and a lumped species containing 2methylpentane, 3-methylpentane, and 2,3-dimethylbutane-assuming that the reaction rates among 2methylpentane, 3-methylpentane, and 2,3-dimethylbutane are fast in relation to the other reaction rates.…”

Statistical Methods in Chemistry

“…Past reviews have covered this subject (109, 129). There have been a number of basic articles in chemical engineering and processing (16,17,31,38,39,44,46,49,53,54,55,61,75,78,79,83,93,98,111,123,127,131,132,137,138), and application articles pertaining to organic chemistry (14,15,18,52,69,105,111) and inorganic chemistry (17,80,81,93).…”

“…Oil, Fats, Rubber, Plastics, and Paints. In the oil industry there are interlaboratory studies (19,103) and application papers on correlation (87) and regression (52). There are applications of optimization in articles pertaining to rubber (82) and plastics (15, 18) and design applications in paint technology (37).…”
