“…The results obtained were comprehensively interpreted from a structural chemistry perspective and used to answer questions relating to how particles of pure and blended pellets made from two different biomass materials combine to form pellets, and the source of inter-particle bonding. As previously stated, assessing biomass for any conversion or pretreatment process requires an understanding of its basic composition [1,3,32]. Therefore, compositional analysis data determined that pure and blended samples of NSP and PSP assessed in this study contained various proportions of major organic and elemental constituents, which were vital to understanding the nature of the materials that were pelletized, and which were equally significant in comprehending how the major components combine to form pellets.…”

“…The use of biomass for the production of energy and valuable chemicals is gaining attention because it is renewable, clean, cheap, and readily available. There are several types of biomass (such as wood, starch, agricultural residues, energy crops, and industrial and municipal solid wastes) suitable for energy conversion after subjecting the biomass to pretreatment processes like pelleting, and the pretreatment method is often determined by the conversion pathway intended for the biomass; however, the need to press biomass into pellets arises from its heterogeneous nature and low energy density, which makes its conversion in energy production systems very problematic [1]. This means that pelleting of biomass is basically a technique used to improve biomass characteristics in the form of a pellet with regular shape, along with higher density, strength, and durability, as well as excellent combustion characteristics and low ash content, which are factors used to define good-quality biomass pellets [2,3].…”

The mechanism of bonding in biomass pellets is such a complex event to comprehend, as the nature of the bonds formed between combining particles and their relevance to pellet quality are not completely understood. In this study, pure and blended biomass pellets made from Norway spruce and pea starch were characterized using advanced analytical instruments able to provide information beyond what is visible to the human eye, with intent to investigate differences in bonding mechanism relevant to quality. The results, which were comprehensively interpreted from a structural chemistry perspective, indicated that, at a molecular level, the major disparity in bonding mechanism between particles of the pellets and the quality of the pellets, defined in terms of strength and burning efficiency, were determined by variation in the concentration of polar functional groups emanating from the major organic and elemental components of the pellets, as well as the strength of the bonds between atoms of these groups. Microscopic-level analysis, which did not provide any clear morphological features that could be linked to incongruity in quality, showed fracture surfaces of the pellets and patterns of surface roughness, as well as the mode of interconnectivity of particles, which were evidence of the production of pellets with dissimilarities in particle bonding mechanism and visual appearance.

In the power supply system, an important place belongs to autonomous power systems. Considering the need to reduce greenhouse gas emissions and the use of renewable energy sources, the primary source of energy in an autonomous power system can be a wood gas generator. The fuel for such a generator is biomass. The wood gas enters the internal combustion engine, which drives a synchronous generator. The resulting electrical energy is supplied to the consumer. The article presents an experimental plant for generating electric energy on the basis of wood gas, and provides the results of studies in the effect of the used power of the synchronous generator on the gasifier fuel consumption and the amount of gas produced by it. The experimental plant contained a downdraft gasifier, the feature of which is that the combustion and recovery zones have the same diameter. The gasifier was equipped with gas purification filters and a gas cooler. The resulting gas was supplied to the internal combustion engine through a special mixer equipped with the air supply control valve. A synchronous generator was used to convert the mechanical energy of the engine into electrical energy. As the engine and electric generator petrol-electric AC set AB-4-T/400-M1 was taken. The petrol-electric set has a rated power of 4 kW and produces a three-phase current with a voltage of 220 V. During operation of an experimental gas-operated plant, the growth of the consumed electric power by 12 times causes the linear growth of gasoline consumption by 1.59 times and air consumption by 1.63 times. During the operation of the wood gasoperated experimental plant, an increase in electrical power consumption by 9.5 times causes a linear increase in gas consumption by 2.14 times and air consumption by 1.38 times. The cost of the generated electricity when using wood gas is 2.4 times less than when using gasoline.

“…They found that fuel/pellet geometry took significant role in gasification process, rather than a chemical composition for varying materials of pellets. Anukam et al (2016) have reviewed the potential utilization of waste bagasse as an energy source through gasification. However, researches on gasification of bagasse is still limited.…”

National energy demand has been fulfilled by non-renewable energy sources, such as natural gas, petroleum, coal and so on. However, non-renewable energy reserves deplete increasingly which can cause an energy crisis. Conversion of biomass into energy becomes one of the solutions to overcome it. Indonesia has an enormous biomass potential especially from sugarcane plantation. Sugarcane plantations produce waste of bagasse abundantly. Commonly bagasse is utilized as energy source by conventional combustion. This research studies the utilization of bagasse as energy source by gasification technology to produce gas fuel. The gasification model used in this research is downdraft gasifier equipped with cyclone to separate gas with solid or liquid gasification products. The result has shown that gasification of bagasse has produced flammable syngas. The increase of bagasse weight increases the amount of syngas of gasification process. Carbon monoxide is the greatest content of syngas, while a few amount of H2, CH4 are also detected. Bagasse through gasification process is very potential source of alternative energy, since it is derived from waste and a cheap material.
