Direct aromatization of methane. Quarterly technical progress report No. 10, January 1, 1995--March 31, 1995

PDF Version Also Available for Download.

Description

Further investigations of assisted pyrolysis by the addition of ethane as a free-radical initiator were carried out during this reporting period. The effects of temperature, space velocity, and ethane/methane ratio, in the presence of quench water, have been addressed. As expected, reaction quenching resulted in lower conversions than without quenching, but also in significantly lower yields of {open_quotes}tar-like{close_quotes} products. High C{sub 2}/C{sub 1} ratios and low space velocities result in significant increases in the {open_quotes}tar-like{close_quotes} product yields. Very low ethane concentrations were required to initiate methane pyrolysis at lower temperatures without a major negative effect on product selectivities.
