Determination of Reaction Kinetic Parameters from Variable Temperature Kinetic Study for Oxidative Addition Reaction on Binuclear Cyclometalated Platinum(II) Complexes

The pseudo-first order rate constants and activation parameters have been determined using two methods, constant-temperature kinetic (CTK) and variable temperature kinetic (VTK), for the oxidative addition reactions of [Pt2Me2(C^N)2(µ-dppf)], (1a, C^N = deprotonated 2-phenylpyridine (ppy); 1b, C^N = deprotonated benzo[h]quinoline (bhq)) with MeI. The results obtained from VTK method are in agre...

technical and legal parameters for determination of river boundary,( case study haraz river)

چکیده با توسعه شهر نشینی و دخل و تصرف غیر مجاز در حریم رودخانه ها خسارات زیادی به رودخانه و محیط زیست اطراف آن وارده می شود. در حال حاضر بر اساس آئین نامه اصلاح شده بستر و حریم رودخانه ها، حریم کمی رودخانه که بلافاصله پس از بستر قرار می گیرد از 1 تا20 متر از منتهی الیه طرفین بستر رودخانه تعیین، که مقدار دقیق آن در هر بازه از رودخانه مشخص نیست. در کشورهای دیگر روشهای متفاوتی من جمله: درصد ریسک...

Predicting Kinetic Parameters of Acetylene Hydrogenation Reaction Via Optimization Techniques

In this study simulation and optimization of an industrial acetylene hydrogenation reactor was studied. Three well known kinetic models were used for a nearly similar catalyst to predict the industrial data. Due to the complexity of the reactions, none of the offered kinetic models could be considered as an exact kinetic model and it is necessary to determine the kinetic parameters. One of the ...

Determination of the Kinetic Constants of a Chemical Reaction in Heterogeneous Phase Using Parameterized Metaheuristics

Estimation of Kinetic Parameters of Coking Reaction Rate in Pyrolysis of Naphtha

The run length of cracking furnaces is limited by the formation of coke on the internal skin of the reactor tubes. The reaction mechanism of thermal cracking of hydrocarbons is generally accepted as free-radical chain reactions. On the basis of the plant output data and the insight in the mechanisms for coke formation in pyrolysis reactors, a kinetic model describing the coke formation has been...
