A kinetic study on combustible coastal debris pyrolysis via thermogravimetric analysis

Abstract

Coastal debris has recently emerged as a serious environmental pollution problem. Coastal debris can be treated using pyrolysis because it consists mainly of combustible materials like plastics (e.g., polyethylene (PE), polypropylene (PP), nylon) and wood. In this study, the pyrolysis characteristics of coastal debris were fully utilized by applying their basic data to fuel production. The initial temperature increased from 330◦C to 380◦C for the nylon fishing net coastal debris sample, from 405.01◦C to 430.08◦C for the PE fishing net coastal debris sample, from 395.01◦C to 419.96◦C for the PP rope coastal debris sample, and from 114.95◦C to 115.02◦C for the wood (bamboo) coastal debris sample. The activation rate of the global activation energy and the pre-exponential factors rose with the increasing heating rate, complementing the reduction rate constant due to the larger growth of the exponential term due to the kinetic models used.
