Methane coking
Web8 uur geleden · In this study, oils from various sources were subjected to pyrolysis conditions; that is, without oxidizer, as the samples were heated to 500 °C, and held at that temperature. The oils studied included: (1) heavy oil from Grassy Creek, Missouri; (2) oil from tar sands of Asphalt Ridge in Utah; (3) mid-continent oil shales of three formations … WebMethane dehydroaromatization (MDA) over Mo-containing zeolite catalysts is a promising reaction for the direct conversion of natural gas to a mixture of liquid BTX aromatics (mainly benzene) and hydrogen. 1 This thermodynamically limited non-oxidative reaction requires temperatures as high as 600–800 °C to achieve a significant methane conversion.
