Potassium-catalysed gasification of carbon with steam: a temperature-programmed desorption and Fourier Transform infrared study

TL;DR: In this paper, it was shown that potassium carbonate, when well dispersed on a surface of carbon prepared from polyfurfuryl alcohol, decomposes at much lower temperatures than bulk carbon carbonate.
Journal ArticleDOI

Low-temperature oxidation of a bituminous coal. Infrared spectroscopic study of samples from a coal pile

TL;DR: In this paper, a Fourier transform analysis of coal samples from a test pile of a bituminous coal which was subject to spontaneous heating was performed. But the results showed that macropore oxidation (a diffusion-limited process across the macroscopic interface of the particle) predominates, and that removal of a small proportion of fines with a relatively large surface area would result in a reduction of spontaneous heating.
Journal ArticleDOI

A Fourier transform infrared spectroscopic study of the oxidation of propylene over supported silver catalysts

TL;DR: The reaction of 2.6 kPa propylene over preoxidized 20% silver on aerosil silica yielded only carbon dioxide, water, and a carbon-rich deposit, which could be oxidized to carbon dioxide and water.
Journal ArticleDOI

The catalytic activity of nickel-substituted mica montmorillonite

TL;DR: In this paper, it was shown that removing metallic nickel from reduced mica montmorillonite (NiSMM) by carbon monoxide destroys the pentane hydroisomerization activity, while leaving the number of acid sites unchanged.
Journal ArticleDOI

Fourier transform ir spectroscopic study of the preparation of a carbon-coupled porphyrin catalyst structure

TL;DR: In this paper, it has been demonstrated by means of Fourier Transform infrared spectroscopy, a specific sample preparation technique, and a background correction procedure, that the chemical coupling of tetra (p -carboxyl)porphyrin to an oxidized carbon surface is accomplished via an ethylenediamide bridge.
