TL;DR: In this paper, numerical simulations of premixed flames burning mixtures of methane and methyl chloride in air are conducted at atmospheric pressure in order to understand the effect of hydrocarbon bound chlorine on hydrocarbon-air flames.

TL;DR: In this paper, the probability of forming XCF 2 + is independent of which isotope of hydrogen is the collision partner, a result consistent with a direct reaction mechanism, and the relative yields of the bond-forming reaction which produces X CF 2 + and the non-dissociative electron transfer reaction, which forms CF 2+, have been determined as a function of the collision energy.

TL;DR: In this article, Titania nanorods (TNRs) in pure anatase phase were synthesized by a hydrothermal technique and calcined at 450°C, and the photocatalytic degradation of p -cresol was carried out under UV-vis irradiation.

TL;DR: In this paper, a kinetic study of the hydrodenitrogenation of quinoline is performed in a batch reactor, over a NiMo(P)/γ-Al2O3 sulfide catalyst, in the range of temperature of 340-360 °C and concentration of 1-2 wt % of qinoline, and the activation energies of every elementary reaction and adsorption enthalpies of nitrogen compounds are calculated.
Abstract: A kinetic study of the hydrodenitrogenation of quinoline is performed in a batch reactor, over a NiMo(P)/γ-Al2O3 sulfide catalyst, in the range of temperature of 340–360 °C and concentration of 1–2 wt % of quinoline. Liquid–vapor mass transfer is considered in the reactor model, and the kinetic expression using Langmuir–Hinshelwood model considers competitive adsorption of reactants, products, and solvents. The activation energies of every elementary reaction and adsorption enthalpies of nitrogen compounds are calculated. The kinetic modeling shows that the hydrogenation of 1,2,3,4-tetrahydroquinoline into decahydroquinoline is the rate-determining step of the principal reaction pathway. The self-inhibition effect due to competitive adsorption of nitrogen-containing compounds is confirmed. The adsorption constants of nitrogen compounds decrease in the order saturated amines > NH3 > aromatic amines, showing that their adsorption strength is related to the basicity of molecules. Moreover, the kinetic model ...

TL;DR: The dissolution of magnesium hydroxide in water for the release of magnesium and hydroxyl ions into the solution to maintain suitable alkalinity is a crucial step in the Mg(OH)2-based CO2 absorption process and the rate of dissolution was investigated under different operating conditions using a pH stat apparatus.
