“…Thus, there is a potential for production of 1.659 kWhr extra electrical energy per kg biodiesel which it proves the sustainability of the system. A sustainable processing system was obtained using this system for diesel engines power generation [24]. The analysis was also supported by Choedkiatsakul et al [25], which utilized even lesser energy consumption of 0.1167 kWh/L of B100.…”

Abstract. Various kinds of palm trees are grown in the tropical regions of the world that provide edible oils for food consumption. They have in common in providing edible oils from the nuts and some from the mesocarp such as oil palm. More than 400 mills in Malaysia have provided more than sufficient energy from the biomass in processing the fruits to crude palm oil. The biomass are the mesocarp fibres, shells or endocarp, empty fruit bunches and palm oil mill effluents. One option of treatment of this biomass is to convert into bio-oil, bio-char, bio-adhesives and methyl ester. Recent research using microwave processing of biomass and biodiesel are given in this paper.

“…Microwaves (MW) are a form of electromagnetic energy located on the electromagnetic spectrum between 300 and 300,000 MHz; a region that lies between infrared and radio frequencies and correspond to wavelengths of 1 cm to 1 m [21,22]. In order to avoid interference with telecommunications and mobile cellular phone frequencies, most microwave reactors (that are typically used for chemical synthesis reactions) and domestic microwave ovens operate at a frequency of 2.45 GHz or around 900 MHz, whilst other frequencies are reserved by the Federal Communications Commission (FCC) for industrial, scientific and medical purposes [23,24].…”

Bioenergy, derived from biomass and/or biological (or biomass-derived) waste residues, has been acknowledged as a sustainable and clean burning source of renewable energy with the potential to reduce our reliance on fossil fuels (such as oil and natural gas). However, many bioenergy processes require some form of pre-treatment and/or upgrading procedure for biomass to generate a modified residue with more suitable properties and render it more compatible with the specific energy conversion route chosen. Many of these pre-treatments (or upgrading procedures) involve some form of substantive heating of the biomass to achieve this modification. Microwave (MW) heating has attracted much attention in recent years due to the advantages associated with dielectric heating effects. These advantages include rapid and efficient heating in a controlled environment, increasing processing rates and substantially shortening reaction times by up to 80%. However, despite this interest, the growth of industrial MW heating applications for bioenergy production has been hindered by a lack of understanding of the fundamentals of the MW heating mechanism when applied to biomass and waste residues. This article presents a review of the current scientific literature associated with the application of microwave heating for both the pre-treatment and upgrading of various biomass feedstocks across different bioenergy conversion pathways including thermal and biochemical processes. The fundamentals behind microwave heating will be explained, as well as discussion of the imperative areas which require further research and development to bridge the gap between fundamental science in the laboratory and the successful application of this technology at a commercial scale.

“…With increasing temperature the moisture content evaporates, the biomass feedstock becomes less microwave absorptive, and the temperature rising rate then slows down. The tangent loss value (microwave absorbability) of a biomass feedstock would be significantly varied by reaction temperatures [114,115].…”

Microwave pyrolysis of lignocellulosic biomass––a contribution to power Africa

Worldwide efforts are being made to increase the use of renewable energy in order to reduce the emission of greenhouse gases. Africa is blessed with abundant resources of fossil fuels as well as renewable energy resources. Yet the continent, especially sub-Saharan Africa, is afflicted with power crisis. For example, in Nigeria, erratic electricity supplies will persist unless the government diversifies her energy sources and adopt new technologies available in the electricity generation sector. International Renewable Energy Agency (IRENA) has called for promotion of increased utilization of the continent's vast renewable energy resources to accelerate development. This review examines the perspective of renewable energy from biomass as an important strategy for a sustainable development in Nigeria. The paper also addresses the use of pyrolysis technology--an efficient thermo-chemical process for energy applications. However, the study presents on applications either to replace fossil fuel in an existing diesel engine-based power generation system or to generate electricity using a gas engine. The work also presented herein addresses the use of industrial-and non-industrial-derived biomass residues for energy purposes with specific example on solid palm oil residues in Nigeria. The current status of pyrolysis technology and its potential for commercial application for bio-fuel production using microwave-assisted pyrolysis in Nigeria are presented. This study will extensively review the recent work on microwave-assisted technology applied to the pyrolysis process. It is estimated that electrical power generation potential at about 500 MW can be obtained by using only the available residues from oil palm industry in Nigeria. This potential can be increased 10-fold with more emphasis on expansion and modernization of oil palm industry in Nigeria. This will benefit in terms of higher revenue from the palm oil export as well as higher renewable energy generation from its biomass residue using the microwave-assisted pyrolysis technology.
