“…Pyrolysis has been applied to various biomass such as coffee grounds [2], waste tea [3], sugarcane bagasse [4], corn cob, wheat straw, rice straw and rice husk [5], coconut shell [6], oil palm trunk [7], palm kernel shell [8], saw dust [9], aquatic biomass [10] and rubber seed shell and kernel [11]. Palm empty fruit bunch (PEFB) from an oil palm plantation is one of the potential biomass to produce biofuels due to its abundant supply and easy to handle.…”

Abstract. The palm oil industry is currently growing rapidly and generating large amounts of biomass waste that is not utilized properly. Palm empty fruit bunch (PEFB), by product of palm oil industry is considered as a promising alternative and renewable energy source that can be converted to a liquid product by pyrolysis process. In this work, pyrolysis of PEFB was studied to produce bio-oil. Pyrolysis experiments were carried out in a bench scale tubular furnace reactor. The effects of pyrolysis temperatures (400-600 C) at heating rate of 10 C/min to optimize the pyrolysis process for maximum liquid yield were investigated. The characteristics of bio-oil were analyzed using FTIR and GC-MS. The results showed that the maximum biooil yield was 44.5 wt. % of the product at 450 C. The bio-oil products were mainly composed of acids, aldehydes, ketones, alcohols, phenols, and oligomers. The chemical characterization showed that the bio-oil obtained from PEFB may be potentially valuable as a fuel and chemical feedstock.

“…The thermochemical conversion process of biomass into energy can be realized by four modes: direct combustion, pyrolysis, liquefaction, and gasification. The pyrolysis technique is a promising mode for the conversion of biomass into gaseous fuel, bio-oil and biochar [10,11]. Understanding the thermal behavior of biomass thoroughly during the pyrolysis conversion process is essential in order to be able to design suitable reactor and temperature control systems, resulting in optimal pyrolysis products.…”

Thermogravimetric analysis experiment to understand thermal decomposition behavior of water hyacinth during the pyrolysis has been performed. Water hyacinth was taken randomly from 2 places, i.e., Selorejo and Sengguruh Dam, district of Malang, Indonesia. Those raw materials were thoroughly cleaned by using the water, then cut and dried in an oven with a temperature range of 80-90 o C for 6 hours. Subsequently, the dried samples were crushed and then filtered to a mesh size of 60. Thermal behavior of the sample was observed through the instrumentality of thermal analyzer at a constant heating rate of 10 °C/min with a nitrogen flow rate of 100 ml/min and a temperature range of 25-1000 °C. The kinetics of active pyrolysis zone were evaluated by Coats-Redfern integral method. The thermogravimetric test results show that the water hyacinth biomass decomposed into four stages during the pyrolysis process. The kinetic parameters in term of activation energy (E), logarithmic frequency factor (log A) and reaction order (n) were 60.74 kJ/mol, 4.77/min and 1.9, respectively.
