“…The increasing worldwide population coupled with the industrialization and the development of emerging economies result in increasing energy demand (Dafnomilis et al, 2017). This contributes to our strong dependence on fossil fuels and to increase greenhouse gas (GHG) emissions to the atmosphere, which lead the scientific community to seek and promote the use of alternative, sustainable and clean energy sources (Küüt et al, 2017). In line with this, a number of European Directives dealing with the biofuel use have emerged, namely: Renewable Energy Directive 2009/28/EC (RED) and Fuel Quality Directive 2009/30/EC, recently amended by the EU Directive 2015/1513 (Küüt et al, 2017).…”

The biofuels production from alternative and renewable raw materials is mandatory to achieve sustainable growth based on a bioeconomy. Eucalyptus bark is a waste generated during the chemical manufacturing of Eucalyptus pulp that can be used as an alternative source of biomass, suitable for the production of biofuels. In this work, Eucalyptus nitens bark (ENB) was fractionated by organosolv treatment for ethanol production. For that, a Doehlert experimental design was carried out to evaluate the dependent variables: temperature (170-200°C), time (30-90 min) and ethanol-water percentage (50-80 %) on delignification of Eucalyptus bark. Organosolv process was suitable for the fractionation of E. nitens bark. After treatment, 74-93 % of glucan was recovered and 25-52 % of delignification was achieved. Delignified ENB was subjected to simultaneous saccharification and fermentation process for bioethanol production. The results showed that the variables temperature and time of organosolv process had significant influence on ethanol production. The organosolv pretreatment improved the ethanol yield from 32 to 99%. This work shows a suitable process for the valorization of Eucalyptus bark into bioethanol.

“…In general, the biofuels can be divided into alcohols and esters [24,25]. The former (most often produced from cereals, maize, potatoes and sugar beet) are alternative fuels for gasoline (low-pressure) engines [26,27]. Methyl or ethyl esters, obtained in the process of rape processing, are added to diesel oil [28].…”

The Effects of Pressure and Temperature on the Process of Auto-Ignition and Combustion of Rape Oil and Its Mixtures

The effects of initial pressure and temperature in a constant volume test chamber with a common rail injection system on the processes of self-ignition and combustion of rapeseed oil and various blends of rapeseed oil with diesel oil are explored. Based on the obtained pressure waveforms the amount of emitted heat was determined, and the tested fuels were compared. The variations of a number of physicochemical characteristics that occur during the combustion processes were evaluated for several mixtures of fuel components. It was found that in the case of blends of rapeseed oil with diesel oil, the best results were obtained for a mixture containing 70 weight percent of diesel oil and 30% of rapeseed oil.

Thermodynamic Fundamentals for Fuel Production Management

An increase of needs for replacement of fossil fuels, and for mitigation of Carbon Dioxide emissions generated from fossil fuels inspires the search for new fuels based on renewable biological resources. It would be convenient if the biological component of the fuel required as little as possible conversion operations in the production. The obvious response is an attempt to use unconverted, neat plant oils as a fuel for Diesel engines. The present paper is devoted to the experimental studies of the combustion process of neat rapeseed oil, and its mixtures with gasoline and ethanol as additional components of the mixtures. The investigation of combustion was carried out in a fixed volume combustion chamber equipped with a Common Rail injection system. It is shown that the instant of ignition, as well as time-dependence of heat emanation, are strongly dependent upon mixture composition. The results enable the design of mixture compositions that could serve as commercial fuel for Diesel engines. Such fuels are expected to fulfill the requirements for the sustainability of road transport.
