Use of ~13c Tracers to Determine Mass-Transfer Limitations on Thermal Cracking of Thin Films of Bitumen

摘要

Thermal cracking of+524 deg.C Athabasca bitumen at temperatures greater than 500deg.C with various thicknesses of feed deposited on the reactor walls was investigated to determine if mass- transfer limitations were significant in controlling product yields. A quartz tube microreactor was used for the bitumen cracking reactions. Volatile products were removed as they evolved by constant purging of the reactor with nitrogen.
