“…HDO improves ignition characteristics by increasing the heating value, increases miscibility with hydrocarbon and improves stability by decreasing organic acid, aldehydes and reactive compounds. However, HDO of bio-oil is very costly, and requires high hydrogen consumption of 400 nitrogen per kg bio-oil [57]; (iv) Esterification is performed by heating a mixture of bio-oil (carboxylic acid) with alcohol and acid catalyst. Esterification converts carboxyl acid in bio-oil into their corresponding esters; reduces the acid number, decreases water content, improves viscosity, fluidity [79], stability, engine ignition, corrosion [143] and promotes ozone oxidation [144].…”

Biomass is an important renewable energy resource which primarily contributes to heating and cooling end use sectors. It is also a promising alternative source of biofuels to replace the depleting supply of fossil fuels. Surprisingly, few writers have been able to draw on the feedstock significance for oil palm empty fruit bunch (EFB) as the biomass resource for biofuels compared to the other types of biomass waste. Therefore, this paper presents a comprehensive review of EFB as a biomass resource presented in four major parts. First, the introduction covers the demand for bio-oil and describes the different kinds of feedstock, the relevance and potential of EFB biomass. Second, the characteristics of biomass are explained before it is upgraded as biofuel, drawing similarities and contrasts between EFB and other sources of biomass. Pyrolysis processes and reactors used for EFB conversion are described, and the factors affecting the bio-oil yield and quality are discussed. Major reactor parameters are summarized and reactor optimization is discussed. Third, comparison on the properties of the bio-oil vs. petroleum in transportation, power generation, and heating are compared followed by prioritizing the bio-oil properties from the most to least critical, revealing the most promising methods for upgrading. Fourth, the environmental impact, including CO2 emission, of the use of EFB as a promising renewable energy resource and a cleaner alternative fuel is recommended. This paper has comprehensively reviewed the conversion of oil palm empty fruit bunches into biofuels, including the similarities and differences between biomasses, the best reactors, its comparison with fossil fuels, and bio-oil upgrading methods. The upgrading mapping matrix is created to present the best upgrading strategies for the optimum quality of biofuels. This paper serves as a one-stop center for EFB conversion into biofuels.

“…Non-edible energy sources have been investigated to develop the second generation of biodiesel. These sources were like palm fatty acid distillate [3], oil palm empty fruit bunches (EFB) [4], wood waste [5], and non-edible seeds such as Jatropha seed [6]. However these non-edible energy sources are limited inventory.…”

Abstract. Biodiesel production from microalgae is one of the solution of the future energy problem, but its production cost is still high. One of the costly stages of this process is the lipid extraction process. It can be reduced by microalgae cell disruption. One of the mechanical method to cell disruption with the lowest energy requirement is hydrodynamic cavitation. This aim of this study is to evaluate the distribution coefficient and the mass transfer coefficient value of lipid extraction of Nannochloropsis sp. assisted by hydrodynamic cavitation and compare with conventional extraction. The hydrodynamic cavitation extraction was done at 34 C, 1 atm. The conventional extraction was done at 34 C, 1 atm with stirring speed 260 and 1000 rpm. The experimental result shows that the distribution coefficient dependent on the temperature with the values for 50, 44, 38 and 34 C were 0.502, 0.394, 0.349, and 0.314 respectively. And it was according to Van' Hoff equation with the values of H was 20.718 kJ/mol and S was 58.05 J/mol/K. The hydrodynamic cavitation extraction was faster than conventional. The mass transfer coefficient values for hydrodynamic cavitation, conventional 260 rpm and 1000 rpm were 7.373, 0.534 and 0.121 1/s respectively.
