Abstract

This chapter discusses coal pyrolysis with methane in a reducing environment. When coal and methane are reacted at 400° C for 64 hours in the presence of catalyst, conversion to liquid products and gaseous hydrocarbons is higher than nitrogen, although significantly lower when hydrogen is used. To achieve higher yields, methane and hydrogen mixtures are employed. Gaseous hydrocarbon yields are maximized at a H2:CH4 ratio of 3:1, and additive effects are seen for liquid hydrocarbon release, providing evidence for potential methane activity under hydropyrolysis conditions. Gaseous products are analyzed by gas chromatography using a Thermal Conductivity Detector (TCD).
