Effect of methane and hydrogen during the thermal cracking of light hydrocarbons for the production of olefins

Conference ·

;
In this paper, the authors discuss the effect of hydrogen and methane addition in the thermal cracking of light hydrocarbons, i.e., ethane, propane and butanes. The results are based on pilot plant work and can be scaled up to commercial size units. In ethane cracking, the addition of hydrogen reduces the ethylene yield at constant ethane conversion; at constant operating conditions, the methane yield is enhanced. However, the adverse effect of hydrogen can be minimized by the addition of methane. In the pyrolysis of a mixture containing ethane, propane and butanes, the presence of hydrogen in the feed results in a small enhancement in the ethylene yield.
