“…In contrast, the extraction sludge showed an active pyrolysis zone between 150 and 550 • C with a passive pyrolysis zone in a higher range (550-1000 • C). Similar results have been reported for the thermogravimetric behavior of the dried solid waste of post-methanated distillery effluent [37]. Figure 8 presents the difference in pyrolysis products yield when each type of biomass waste-press mud, powder vinasse, and extraction sludge-was used as feedstock for slow pyrolysis.…”

The effluents of the sugar and bio-ethanol industry, mainly vinasse as well as lignocellulosic waste, are produced in high volumes. Therefore, their treatment and valorization would reduce the environmental impact and make this industry more productive and competitive. The purpose of this study was to determine the potential use of press mud (lignocellulosic waste), vinasse powder, and vinasse sludge from an extraction process with ethanol, as raw materials for conventional pyrolysis evaluating the physicochemical characteristics that affect this thermochemical process, such as calorific power, density, ash content, volatile material, moisture and nitrogen, sulfur, carbon and hydrogen content, thermogravimetric profile, and quantification of lignin cellulose and hemicellulose. The batch pyrolysis experiments showed that all three wastes could be converted successfully into more valuable products. The powder vinasse led to the formation of the lowest content of bio-char (42.7%), the highest production of volatiles (61.6 wt.%), and the lowest ash content (20.5 wt.%). Besides, it showed the high heating value of 15.63 MJ/kg. Meanwhile, the extraction sludge presented the highest liquid yield (32%) with the lowest gas formation (18.2 wt.%) and the lowest heating value of 8.57 MJ/kg. Thus, the sludge could be a good feedstock for production of bio-oil and bio-char.

“…Thermal decomposition of coal plays key role in gasification and co-combustion of coal (Kelebopile et al 2011;Kajitani et al 2006). During the pyrolysis of coal two processes take place first is depolymerisation in which water vapour, gas and tar are formed and secondly repolymerization process when char forming takes place (Zhang et al 2015;Naveen and Premalatha 2014;Li et al 2014Li et al , 2017. Mass loss of coal with respect to time and temperature can be measured by using pyrolysis (Duan et al 2016(Duan et al , 2017.…”

The present research work deals with the thermogravimetric analysis (TGA) and kinetic analysis of three typical Indian low rank coals selected from Indian coal mines at various temperature ranges. Experiments were performed at four different heating rate (50, 100, 150, 200 K/min) for three typical Indian low rank coal samples in a nitrogen atmosphere from temperature range 30-950°C. The peak of temperature and mass loss for Indian low rank coal were evaluated. Current study also deals for the utilization and the behaviour of Indian low rank coal during the pyrolysis by using TGA. The activation energy for Indian low rank coal were calculated based on TGA data by using Friedman Method. Corresponding calculated mean value of activation energy for Indian low rank coal is found 49.132 kJ/mol. These experimental results help to explain and predict the behaviour of Indian low rank coal in practical applications.

“…The PMDE still contains high organic matters loading with dark color. 4 It is estimated that an industry producing 50 000 liters per day of alcohol will approximately discharge 700 000 liters of PMDE containing 65 000 ppm of solids per liter. Hence the potential of solid waste from such an industry is 45.5 tonnes per day.…”

“…3 Dried powder of PMDE waste will have a good caloric value which could be used as a good source of fuel for power generation. 4 Concentration and combustion of effluent technique are still under testing 6 and not much research work are available on this technique. The ash collected aer combustion of PMDE is rich in inorganic salt content like potassium, magnesium, etc., which could also be recovered by a suitable chemical process.…”

“…This co-ring approach is possible only up to 30% mixing of PMDE solid waste on a thermal basis with coal, since due to high alkaline chlorides constituents in PMDE solid waste. 4 Although many technical issues are yet to be resolved, co-combustion of PMDE solid waste may be the best energy recovery option for sugar mill power producers at present.…”
