Black carbon production from pyrolysis and combustion of pyrolysis oil of asphaltite, waste tire and wood

Abstract

Ethylene, natural gas and oil is used as the raw material in the combustion production of black carbon by soot formations. Black carbon is useful with the increased surface area as soot or activated carbon micro particles. It is traditionally believed that soot formation occurs in combustion of oil by certain amount of oxygen. As a result of this, a gas concentration gradient is needed between the carbon and the oxygen for soot production from the gaseous or liquid fuel. Therefore, certain amount of carbon can only form for soot compounds that readily provide submicron black carbon product. Black carbon involves allotropic soot produced by not full combustion and removal of carbon matter in a closed-loop circulating batch system. This study searched that firstly, pyrolysis of low ash Şırnak asphaltite and washed with flotation device provided less ash Turkish lignites(less than 10% of the level in existing advanced clean lignite washery plant manufactured) with waste wood and tyre, secondly, combustion of pyrolysis oil of the retort for black carbon production on which the furnace gas parameters by examining the highest black carbon efficiency is obtained, and thirdly, according to the optimum design parameters of the pilot plant, gas furnace equipment investigated. The 32% soot yield from the 50% coal and 20%wood and 30% waste tyre weight rate were provided in the retort furnace.
