Palm Waste

Malaysian agro-industrial sector produces considerable quantity of solid palm waste biomass and potential exploitation of this waste residue is necessary for economic and environmental aspects. The Oil Palm Shell (OPS) waste biomass was subjected to multimode microwave pyrolysis at 2.54GHz with coconut activated carbon layers. The microwave power and N2 flow rate were varied to investigate its effects on heating profile, product distribution and bio-oil composition using fixed coconut activated carbon loading. The OPS surface and bed temperature, heating rate, pyrolysis product distribution and bio-oil composition was found dependent on microwave power and N2 flow rate. The highest bio-oil yield of 31 wt% was obtained both at 300W and 600W using 4LPM. The phenol content varied from 34.02-44.42% of GC-MS area with highest value at 300W and 8LPM. Bio-oil from this study also contained 1,1-dimethyl hydrazine of 7.04-13.01 % of GC-MS area.

Bimetallic Material

The catalytic and thermal decomposition of plastic waste to fuels over low-cost catalysts like zeolite, clay, and bimetallic material is highlighted. In this paper, several relevant studies are examined, specifically the effects of each type of catalyst used on the characteristics and product distribution of the produced products. The type of catalyst plays an important role in the decomposition of plastic waste and the characteristics of the oil yields and quality. In addition, the quality and yield of the oil products depend on several factors such as (i) the operating temperature, (ii) the ratio of plastic waste and catalyst, and (iii) the type of reactor. The development of low-cost catalysts is revisited for designing better and effective materials for plastic solid waste (PSW) conversion to oil/bio-oil products.

Pyrolysis Of Biomass

The objective of this study is to catalytically upgrade fast pyrolysis vapors of sawdust using various Fe-based catalysts for producing phenolic-rich bio-oil by analytical pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) technique. A variety of parameters, including support characteristic, calcination temperature, pyrolysis temperature, as well as the catalyst-to-biomass ratio during the pyrolysis process were evaluated for their effects on product distribution of bio-oil. GC-MS analysis showed that compared to Fe–Mg and Fe–Al catalysts, the developed Fe–Ca catalyst significantly promoted the formation of phenols and its derivatives. The phenolic concentration declined with increasing calcination temperature and pyrolysis temperature, while increased monotonically along with increasing catalyst-to-biomass ratio. The phenolics concentration was high upto 81% (peak area) under optimum conditions of calcination temperature of 500 °C, pyrolysis temperature of 600 °C and catalyst-to-biomass ratio of 10. At higher catalyst-to-biomass ratio of 20, phenolics (88.03% in peak area) and hydrocarbons (including 7.86% of aromatics and 4.1% aliphatics) were the only two components that can be detected, with all the acids, aldehydes and ketones completely eliminated. This indicated the excellent capability of developed Fe–Ca catalyst in promoting the decomposition of lignin in biomass to generate phenolic compounds and meanwhile inhibiting the devolatilization of holocellulose.

Biomass Potential

Abstract The agricultural sector produces solid waste biomass abundantly. However, this biomass potential has not been utilized optimally. Indonesia as the world’s number one producer of oil palm plantations produces enormous biomass potential. Oil palm empty fruit bunches (EFB) are the largest solid waste with a fraction of around 20-23% of fresh fruit bunches. Conventionally, it is only used as plant mulch in plantations areas. However, this biomass can still provide added value to bioenergy products through thermochemical pyrolysis conversion. The study was conducted with EFB raw materials that have been chopped with a size of <2mm, heating rate of 10C/minute with temperature variations of 350°C, 400°C, 450°C, 500°C, and 550°C. The results showed that the EFB pyrolysis at low temperatures produced biochar products, and at high temperatures, it produced maximum product in the form of bio-oil. In the EFB pyrolysis process, biochar with an optimum yield of 36.92% was produced at 350°C, and bio-oil with an optimum yield of 46.60% was produced at a temperature of 550°C.
