Chemiluminescence, Dioxetanes, Reaction Kinetics, Spectra, Biradicals The thermal decomposition of 1,2-diadamantyldioxetane was studied by kinetic and spectroscopic methods. Spectra of the chemiluminescence emitted during the thermally induced decomposition of 1,2-diadamantyldioxetane, tetramethyldioxetane and trimethyldioxetane were obtained and the influence of quenchers and radical-scavenger...

The pyrolytic conversion of methane for the production hydrogen and carbon was investigated over nonporous α-Al2O3 surfaces in range 900–1300 °C. Two devices were used: i) a single particle reactor to determine deposition rate at various temperatures ii) fixed bed which both measured. It observed that 1000 °C below, selectivity towards (and hydrogen) initially low fresh (e.g. 38% 250 s reaction...

In this work, experimental kinetics data of methane hydrate decomposition at temperatures ranging from 272.15 to 276.15 K and at pressures ranging from 10 to 30 bars were modeled by using chemical affinity. This model proposed a macroscopic model which is independent of any intermediate mechanism like heat or mass transfer. The results show there is good agreement with experimental data. Al...
