Abstract

This paper describes the mechanism of a developed process—an integrated pyrolysis-tar decomposition process—to produce oil palm empty fruit bunch- (EFB-) derived biochar with additional solid carbon within the biochar bodies, produced by decomposition of tar vapor on its pore surface, using the chemical vapor infiltration (CVI) method. The product, carbon-infiltrated biochar, was characterized to investigate the possibility to be used as partial coke breeze replacement in ironmaking. Carbon-infiltrated biochar is proposed to be utilized for a sintering process that could reduce the consumption of coke and CO2emission in iron-steel industry.

Highlights

Being one of the largest palm oil producers, Malaysia has abundance of oil palm residues generated throughout the year. e high volume of oil palm biomass residues incurs high management and disposal costs. e inefficiency of waste management causes environmental deterioration because of the natural methanation process from biomass dumping [1].We are interested in the utilization of oil palm empty fruit bunch (EFB), biomass that is abundantly available but marginally utilized in Malaysia

Carbon-infiltrated biochar produced using the integrated pyrolysis-tar decomposition process was characterized for its carbon type and microstructure, as well as to understand the mechanism of the developed process. is carbon deposition process came from decomposition of EFB-derived biotar that took place within the pores of EFB-derived biochar. e conversion of EFB into porous biochar involved decomposition of its components, hemicellulose, cellulose, and lignin. e chemical and physical properties of deposited carbon within the porous biochar were investigated. e chemical structures for components of tar produced by fast pyrolysis, components of gases, and structure of biochar are presented

Introduction

Being one of the largest palm oil producers, Malaysia has abundance of oil palm residues generated throughout the year. e high volume of oil palm biomass residues incurs high management and disposal costs. e inefficiency of waste management causes environmental deterioration because of the natural methanation process from biomass dumping [1].We are interested in the utilization of oil palm empty fruit bunch (EFB), biomass that is abundantly available but marginally utilized in Malaysia. Is paper discusses the mechanism of carbon-infiltrated biochar production by the integrated pyrolysis-tar decomposition process.
