Microwave Pyrolysis Assisted With Carbon Based Absorbent: An Overview

Abstract

Over recent years, there has been an explosive growth of interest in the development of novel gel-phase materials based on small molecules. It has been recognised that an effective gelator should possess functional groups that interact with each other via temporal associative forces. This process leads to the formation of supramolecular polymer-like structures, which then aggregated further hence, gelating the solvent. Supramolecular interactions between building blocks that enable gel formation include hydrogen bonds, interactions, solvatophobic effects and van der Waals forces.

An Exploration of Modified Microwave-assisted Rapid Hydrothermal Liquefaction Process for Conversion of Palm Kernel Shells to Bio-oil

“…During the pyrolysis process, high heating rates and pyrolysis temperature can always be reached as well as shorter residence time if microwave absorbents are mixed with feedstock for biomass. This is due to the ability of microwave absorbents to absorbs the microwave energy and conveyed it to the poor absorbing material [15]. Although microwave absorbents are great material that would help in increasing the pyrolysis end product especially bio-oil, however, the possibility for the volatile matter to enter secondary reactions where the vapour would break down into non-condensable gases are high due to sudden elevated temperature during the process which could reduce the yielding of bio-oil [11].…”
