“…The results obtained are comparable with those reported for agricultural plant biomass, i.e. from 15 to 17 MJ kg -1 for wet biomass or up to 19 MJ kg -1 for completely dried biomass (Dharmadi et al, 2006;Niedziółka et al, 2015). The highest density was noted for MONG (1 289 kg m -3 ) and the lowest was exhibited by the pharmaceutical glycerine (1 264 kg m -3 ).…”

A b s t r a c t. The technology of transesterification of biodiesel obtained from many agricultural products, which are often referred to as renewable resources, yields substantial amounts of by-products. They exhibit various properties that prompt scientific research into potential application thereof. Various spectroscopic methods, e.g. Fourier transform infrared spectroscopy, are being increasingly used in the research. In this paper, we present the results of Fourier transform infrared spectroscopy spectroscopy analyses of technical glycerine, distilled glycerine, and matter organic non glycerol, i.e. by-products of biodiesel production. To facilitate the spectroscopic analysis, a number of parameters were determined for all the materials, e.g. the calorific value, water content, sulphated ash content, methanol content, acidity, as well as the contents of esters, heavy metals, aldehydes, nitrogen, and phosphorus. The results indicate that the analysed products are characterised by a comparable calorific value in the range from 11.35 to 16.05 MJ kg -1 in the case of matter organic non glycerol and technical glycerine. Observation of changes in the position of selected peaks in the range of 3700-650 cm -1 in the Fourier transform infrared spectroscopy method facilitates determination of the level of degradation of the analysed material. Changes in the wavelength ranges can be used for monitoring the formation of secondary oxidation products containing carbonyl groups.

The growing consumption of energy and the goals established in the COP21 to diminish greenhouse gases have been bases for the development of energy industries that use renewable sources. Biomass pellets have become interesting alternatives due to their physicochemical characteristics and advantages over traditional wood. This document sought to conduct a review of the behavior of the international market, emphasizing on the principal producer and consumer countries, prices of biofuel commercialization, as well as the different research trends related to this market. The European Union has become the principal market for biomass pellets with 94% growth in the last decade, sale prices around 200 and 250 €/t and an increasing need to import these biofuels. Research has focused mainly on four big areas, like pellet quality, new materials, market analysis, and combustion characteristics of the pellets. Understanding these research trends and knowing the existing market can permit the development of the currently inexistent Colombian industry for the use of this type of biofuel Keywords: Pellets, Biomass, Market, Solid Fuels, Renewable Energy. ResumenEl creciente consumo de energía y las metas establecidas en el COP21 para la disminución de gases de efecto invernadero han sido bases para el desarrollo de industrias energéticas que emplean fuentes renovables.

El presente documento busca realizar una revisión al comportamiento del mercado internacional haciendo énfasis en los principales países productores y consumidores, los precios de comercialización del biocombustible, así como las diferentes tendencias en investigación relacionadas con este mercado. La Unión Europea se ha consolidado como el principal mercado para pellets de biomasa con un crecimiento del 94% en la última década, precios de venta alrededor de 200-250 €/t y una cada vez mayor necesidad de importar estos biocombustibles. Las investigaciones se han enfocado principalmente en cuatro grandes áreas como calidad de pellets, nuevos materiales, análisis de mercados y características de la combustión de pellets. Entender estas tendencias de investigación y conocer el mercado existente pueden permitir el desarrollo de la industria colombiana actualmente inexistente para el aprovechamiento de este tipo de biocombustible.

“…It has been demonstrated that over certain moisture content it's not possible to create a coherent pellet due to the high relaxation of the material on elimination from the die [54]. In addition, a notable decrease of the ash content was also observed by pelletization, which is possibly associated with the increased combustion temperature of the pellets compared to that of powder fuel [55,56]For example, the ash content decreased from 21.1% for crushed corn cob to 3.1% for corn cob pellet and from 14.7 for wheat dust to 4.1% for wheat dust pellet as the low amount of ash for the binder that reach to 4.28%. The decreased ash contents and decreased moisture contents implied that higher thermal efficiency could be achieved during the combustion of the biomass pellets [57,58].…”

A B S T R A C TThis study concentrates on pelletization of powdered corn cob and wheat dust with 40% Epoxy binder. Two cylindrical pellets of different sizes and a new hexagonal one were investigated in this work. By densification process, the bulk density increased 8-10 times, having its maximum value fora hexagonal shape (new shape). It was found that the compressive resistance, the water resistance and the impact resistance of the pellets were in general higher for pellets produced at higher pressure. It was found that due to the binder and pelletization, the fuel quality was enhanced compared to the raw biomass as: the moisture content decreased, both fixed carbon and carbon contents increased, ash content reduced, oxygen content decreased and higher heating value (H.H.V) increased. Scanning Electron Microscopy was used to identify the binding mechanism of biomass dust particles in pellets. Pelletization process had improved combustion characteristics compared to raw biomass as: high combustion temperature ranges [T_onset becomes lower and T_offset becomes higher], maximum weight loss rates decreased and reduced residues which leads to a higher combustion efficiency. The analysis of ash yields of combustion process was investigated. It was found that the fouling index (FI) and slagging index (SI) tendency of wheat dust pellets are higher than that of corn cob pellets.
