摘要: The aim of this study is to examine the methane conversion into C2 hydrocarbons at resistive metal catalyst – electrically heated molybdenum plate - and determine effect H2 content in reaction gas mixture on process characteristics. For hydrogen-free pyrolysis maximum reaches 60% temperature 1300 °C product selectivity has clearly defined maxima: for ethane it a 1050 (6%), ethylene 1150 (10%) acetylene range 1250-1300 (28%). With further increase drops significantly due intensive decomposition carbon hydrogen. hydrogen addition positively effects unsaturated hydrocarbon (ethylene acetylene) negatively methane.
