TLDR
In this article, it was shown that carbon burning in oxides of silica, alumina, and magnesia shows both quantitative and qualitative similarities to the combustion of pure graphite, and suggest the existence of a basic, uncatalyzed burning rate on such oxides.About:

Heterogeneous Catalyst Deactivation and Regeneration: A Review
TL;DR: In this article, a review on deactivation and regeneration of heterogeneous catalysts classifies deactivation by type (chemical, thermal, and mechanical) and by mechanism (poisoning, fouling, thermal degradation, vapor formation, vapor-solid and solid-solid reactions, and attrition/crushing).
Journal ArticleDOI
The intrinsic reactivity of carbons to oxygen
TL;DR: In this paper, the reaction rates per unit area of pore surface in the absence of any mass transfer restrictions, for combustion of a wide range of carbons have been calculated from published data.

The combustion of methane on platinum—alumina fibre catalysts—I: Kinetics and mechanism
David L. Trimm,Chi-Wai Lam +1 more
TL;DR: In this article, the oxidation of methane has been studied over platinum supported on porous and nonporous alumina fiber, and the kinetics of the reaction have been measured at temperatures above and below 815 K where a change in the apparent activation energy was found.

Dynamic modeling and simulation of a fluidized catalytic cracking process. Part I : Process modeling
In-Su Han,Chang-Bock Chung +1 more
TL;DR: In this article, a detailed dynamic model of a typical FCC unit that consists of the reactor, regenerator, and catalyst transfer lines is developed, where a distributed parameter model is presented for the reactor riser to predict the distributions of the catalyst and gas-phase velocities, the molar concentrations of 4 lump species, and the temperatures.

Polyfunctional Heterogeneous Catalysis
TL;DR: The criteria and principles involved have general applicability not only in catalytic hydrocarbon transformations, but also in other catalyzed organic reactions, in some of the largest scale industrial processes, in chemical laboratory experience, and in the biochemical world of life processes.
