Investigation of products of thermal methane conversion in hydrocarbon mixtures by mass spectrometry

Abstract

The influence of ethylene/acetylene admixture on catalytic methane pyrolysis is investigated. Mass spectrometric analysis of the products of reactions in synthesis of carbon structures by thermal chemical gas-phase deposition is carried out for different temperatures, gas mixture compositions, and catalyst concentrations. It is shown that in the presence of ethylene and acetylene, there occurs partial methane decomposition at lower temperatures.
