“…Biomass has attracted a great attention as a source for renewable and clean energy (Chen et al, 2015;Ertaş and Hakkı Alma, 2010). Biomass can be converted directly into liquid, gaseous and solid fuels, usable for transport, heat and power production (Demiral et al, 2012).…”

The aim of the present work is to develop processes for the production of bio-oil and bio-char from algae waste using the pyrolysis at controlled conditions. The pyrolysis was carried out at different temperatures 400-600°C and different heating rates 5-50°C/min. The algal waste, bio-oil and bio-char were successfully characterized using Elemental analysis, Chemical composition, TGA, FTIR, H NMR, GC-MS and SEM. At a temperature of 500°C and a heating rate of 10°C/min, the maximum yield of bio-oil and bio-char was found to be 24.10 and 44.01wt%, respectively, which was found to be strongly influenced by the temperature variation, and weakly affected by the heating rate variation. Results show that the bio-oil cannot be used as bio-fuel, but can be used as a source of value-added chemicals. On the other hand, the bio-char is a promising candidate for solid fuel applications and for the production of carbon materials.

“…It is observed that with the increase in heating rate, the temperature ranges for start and endpoint increase due to thermal lag as shown in Table . This means increasing heating rate shifts the reaction zone to the higher temperatures for coal and solid wastes . The effect of heating rate on thermal decomposition of solid wastes and coal is presented in Figure B.…”

Energy crisis and solid waste management have remained challenging issues for authorities in Pakistan. These issues tend to rise with increasing population and economic growth of the society. Therefore, environmentally sustainable waste‐to‐energy program must be part of the waste management system since they may substitute fossil fuels with renewable energy sources by enabling energy recovery instead of landfill of solid wastes. In this work, the combustion characteristics of fossil fuel (coal) and solid wastes such as municipal solid waste (MSW) and refuse‐derived fuel (RDF) were investigated by thermogravimetric analysis (TGA) to compare their thermal decomposition behavior. Furthermore, proximate and ultimate analyses of these samples were carried out along with their heating values. The TGA profiles of samples indicate low reactivity of coal, whereas solid wastes present greater reaction rate reflecting their low ash and high volatile contents. It was found that the heating value of RDF sample was close to that of coal. The obtained thermal data were used to calculate the kinetic parameters using Arrhenius and Coats‐Redfern models with different reaction mechanisms. According to these models, the fuels could be arranged in order of activation energy as coal > RDF > MSW. The percentage difference between activation energy values found from Arrhenius and Coats‐Redfern models was in the range of 4.1%‐26.5%. However, the Coats‐Redfern model exhibited consistency in activation energy values, followed by a high value of R2. These results of the TGA could be very helpful to predict the combustion dynamics and confirm that MSW and RDF may be used as sustainable fuels, to meet the prevailing challenges of the energy crisis and solid waste management.

This research reports the use of cooking oil waste and moringa biodiesel and their blends into mineral diesel and the influence of the storage conditions. The behavior of the blend between moringa and cooking oil waste and biodiesel were evaluated through thermogravimetric analysis and the data were used in the determination of the kinetic parameters of the blends as activation energy and pre-exponential factor and the values found were similar to reported in literature for others samples of biodiesel. The quality of the blend between biodiesel and diesel and the influence of storage conditions were evaluated through the determination of the acid value of the samples. The acid value for the samples that contained mineral diesel was virtually constant. The acid values of the samples of biodiesel were not in accordance with Brazilian legislation, but did not affect the quality of the blend with mineral diesel. The average values of activation energy for waste cooking oil and moringa biodiesel were 70.04 ± 2.99 and 53.80 ± 6.83 kJ mol -1 , respectively.
