CO-PRODUCTION METHOD OF HYDROGEN AND CARBON BLACK BY THERMAL CRACKING OF NATURAL GAS

摘要

PURPOSE: A method for the co-production of hydrogen and carbon black by thermal cracking of natural gas without emitting carbon dioxide is provided. CONSTITUTION: The method comprises the steps of introducing natural gas such as methane into a tubular reactor(11); heating the natural gas at 1100 to 1200 deg.C, and separating hydrogen gas using a hydrogen-methane separator(12) such as membrane filtration or adsorption process, wherein the retention time of the natural gas in the reactor is about 0.3 to 0.5 sec.
