Ultimate and proximate analysis of Malaysia pineapple biomass from MD2 cultivar for biofuel application

Abstract

MD2 pineapple is a highly demanded hybrid pineapple other than Josephine and Sarawak. The decomposition process of the pineapple biomass by burning may contribute towards carbon emission and increase the greenhouse effect. To address these negative impact, this biomass can be used as a raw material for the alternative solid biofuel to coal and substitute coal for the application in heavy industry or domestic use. The aim of this study is to investigate the characteristic of the MD2 pineapple biomass for their use as a feedstock for biofuel and energy production. The ultimate analysis was carried out by using CHNS Elemental Analyser, where the proximate analysis was identified by the thermo-gravimetric (TGA) analysis under dynamic condition. The results of the conducted study were compared with other biomass reported in the past literature. The ultimate analysis of the MD2 pineapple (i.e. 43.43 wt% C, 6.69 wt% H for leaf and 41.09 wt% C, 6.705 wt% H for stem) appears to correlate with the ultimate analysis range of the other biomass which is used as a raw material of the solid biofuel. The thermo-gravimetric analysis showed that each single part of the MD2 pineapple had pyrolysis and combustion characteristic based on its own main pseudo-components (hemicellulose, cellulose and lignin). The characteristics of the MD2 pineapple had ensured the potential of biomass as raw materials for alternative solid biofuel.
