PROCESS AND APPARATUS FOR DECOMPOSING WASTE LUBRICANT AND GENERATING HYDROCARBON GAS BY USING ELECTRIC ARC

摘要

PURPOSE: Provided are a process and an apparatus for cracking and decomposing a waste lubricant and generating hydrocarbon fuel gas having a low molecular weight, a low boiling point, and a high calorie by using electric arc. CONSTITUTION: The apparatus comprises: a storage container(10) to store the waste lubricant(11); a pump(15) to transfer the waste lubricant(11) from the storage container(10); a lower electrode stick(70) connected with the pump(15), which has a channel(75) to transfer the waste lubricant(11); an upper electrode stick(60) keeping a fixed interval(80) against the lower electrode stick(70), which generates the electric arc(90) with the lower electrode stick(70); a decomposing container(20) equipped with the upper and the lower electrode sticks(60)(70), which stores the waste lubricant effused to the interval(80) of the upper and the lower electrode sticks(60)(70), and has an outlet hole(21) to exhaust the hydrocarbon gas generated by the electric arc(90); a power supply and control means(50) to supply power to the electrode sticks(60)(70) and to control the power supply.
