Kinetic Studies on the Dimerization of Isobutene with Ion-Exchange Resin in the Presence of Water as a Selectivity Enhancer
Sandip Talwalkar,Mehul Chauhan,Preeti Aghalayam,Zhiwen Qi,Zhiwen Qi,Kai Sundmacher,Kai Sundmacher,Sanjay M. Mahajani +7 more
TL;DR: In this paper, a batch reaction of isobutene was carried out in a batch reactor over a temperature range of 65−95 °C in the presence of ion-exchange resin as a catalyst and isooctane as a solvent.
Journal ArticleDOI
Evaluation of CO2 gasification kinetics for low-rank Indian coals and biomass fuels
TL;DR: In this paper, isothermal and non-isothermal thermogravimetric analysis (TG) with CO2 as gasifying agent was used to study the gasification of solid fuels such as coals, lignite and biomasses.
Journal ArticleDOI
Process Analysis for Dimerization of Isobutene by Reactive Distillation
Ravindra S. Kamath,Ravindra S. Kamath,Zhiwen Qi,Zhiwen Qi,Kai Sundmacher,Kai Sundmacher,Preeti Aghalayam,Sanjay M. Mahajani +7 more
TL;DR: In this article, the influence of important design and operating parameters on the performance of the reaction in a hybrid reactive distillation column is studied through process simulations, and the results show that a high selectivity toward diisobutene can be achieved along with adequate temperature control in the presence as well as absence of polar components.
Journal ArticleDOI
Roles of thermal and radical quenching in emissions of wall‐stabilized hydrogen flames
TL;DR: In this paper, a numerical study of the combustion of H{sub 2}/air mixtures impinging on surfaces has been performed, using detailed chemistry and multicomponent transport, in order to elucidate the roles of surface thermal and chemical quenching in pollutant emissions.
Journal ArticleDOI
Surface reaction mechanism development for platinum-catalyzed oxidation of methane
TL;DR: In this paper, a new C1 reaction mechanism for methane oxidation on Pt is presented, consisting of 31 reversible, elementary, thermodynamically consistent steps, and activation energies are calculated using the semi-empirical bond order conservation (BOC) technique.
