PRODUCING METHOD FOR CARBON BLACK AND HYDROGEN FROM WASTE LUBRICATING OIL

摘要

PURPOSE: A method for manufacturing hydrogen and carbon black from waste lubricating oil is provided to prevent environmental pollution by preventing the generation of byproducts such as carbon dioxide during a waste lubricating oil decomposing process. CONSTITUTION: A method for manufacturing hydrogen and carbon black from waste lubricating oil includes the following: waste lubricating oil is vaporized; the vaporized lubricating oil and inert gas are supplied into a fluidized bed reactor(10) with a carbon black catalyst; the vaporized waste lubricating oil is catalytic decomposed; carbon black is obtained and is discharged through a discharging pipe equipped at the fluidized bed reactor; a gas mixture containing hydrogen, non-reacted waste lubricating oil, and entrained carbon is collected with a cyclone(50) equipped at the outlet of the fluidized bed reactor; the entrained carbon is separated from the collected gas mixture; the mixture of the hydrogen and the non-reacted waste lubricating oil is transferred to a pressure converting absorbing column(60); and hydrogen is separated from the mixture.
