Pyrolysis decomposition of tamarind seed for alternative fuel

Thermal and catalytic slow pyrolysis of Calophyllum inophyllum fruit shell

“…3(a). Above 400°C the flue gas yield increases and similar observations were recorded by other researchers (Naqvi et al, 2013;Kumar et al, 2010;Wang et al, 2010;Kader et al, 2013;Heo et al, 2010;Islam et al, 2010;Pan et al, 2010). The char yield decreases from 28% wt to 25% wt as the process temperature increases from 350 to 550°C.…”

“…This is due to the vaporization of moisture and decomposition of some volatile compounds present in the CI bio mass, at low temperature. Similar observations were made by other researchers (Kader et al, 2013;Shadangi and Mohanty, 2014). In the second phase it is observed from the DTG curve that the maximum rate of mass loss is up to 351.5°C, and this could be due to degradation of hemicelluloses content.…”

“…3(b). At higher particle sizes there is incomplete decomposition of bio mass due to lower thermal conductivity resulting in more char and less flue gas (Kader et al, 2013;Heo et al, 2010;Islam et al, 2010). The pyrolytic oil yield shows increasing trend up to 41% wt for heating rate from 10 to 40°C/min.…”

Double Distribution Activation Energy Model as Suitable Tool in Explaining Biomass and Coal Pyrolysis Behavior

“…Moreover, pyrolysis is a complex process whose kinetic parameters are difficult to obtain through models due to the high number of products, not easily identifiable in experiments. Pyrolysis can be generally described as a two-step process [7,8]: a primary step occurring in a lower temperature range, where light gas and tar are released, and a secondary one, at higher temperatures, where the release of light gas continues and the aromatization of the biomass macromolecules leads to char production. A large number of kinetic models were proposed in the literature [9,10].…”

Experimental Studies on Four Stroke Diesel Engine Fuelled with Tamarind Seed Oil as Potential Alternate Fuel for Sustainable Green Environment

“…As the feedstock is available in large quantity in the world, the production of bio-oil is of great interest for pyrolysis study and is a novel matter of subject for future research. Kadera et al (2013) conducted experiments on optimum extraction of tamarind seed oil from the tamarind seed through the fire tube heating transesterification process and concluded that tamarind seed oil as one of the suitable alternate fuel for diesel. Shameer and Ramesh (2017) examined the performance consequences of an eco-friendly substance on the diesel engine and concluded that up to 20% biodiesel blend showed the close behaviour of BTE, BSFC and tailpipe emissions with greater penalty of NOx when analysed with base fuel.…”
