Abstract in another language

This article presents the results of a study of thermal decomposition of model hydrocarbons based on the concept of a two-product coking plant. This plant works without the common, but expensive cleaning of the raw coke-oven gas. The only products are coke and reduction gas. The latter can be produced either by thermal cracking or by partial oxidation of the raw coke-oven gas. As a contribution to the modelling of these processes, the thermal decomposition of the hydrocarbons that are the main components of the raw gas - naphthaline, toluene, benzene, ethylene and methane - was studied. The experiments were conducted in a laboratory scale flow unit. The influence of different parameters on conversion rates and product yields, e. g. the reaction temperature and the residence time, was measured. The reaction kinetic for the thermal decomposition of each model hydrocarbon is presented. The reactivity is increasing as follows : methane < benzene < naphthaline < ethylene < toluene. Hydrogen inhibits the conversion of all hydrocarbons used in the experiments. Steam has only little influence.
