The present study addresses pyrolysis behaviour and potential of Samanea saman seeds (SS) towards its bioenergy potential using thermogravimetric analyzer and in a cylindrical pyrolyzer (semi-batch reactor). Pyrolysis kinetic behaviour of biomass was carried out using Kissinger, Distributed Activation Energy Model (DAEM) and Miura-Maki-Integral method (MMI) while thermal pyrolysis was carried out in a cylindrical shaped semi-batch reactor. Kinetic results confirmed that the average activation energy was found 118.24 kJ mol−1, 168.70 kJ mol−1, and 97.87 kJ mol−1 for Kissinger, DAEM, and MMI model respectively. Further, thermal pyrolysis of SS biomass yielded 44.20 wt% yield of pyrolytic liquid (31.20 wt% pyrolytic oil/organic oil and 13 wt% aqueous fraction). Characterization results of pyrolytic oil showed the presence of higher viscosity (86.01 cSt), higher oxygen content (33.11%), and lower ash content (0.46 wt%) and gross heating value. FTIR analysis confirmed mainly the presence of aromatics, acid, alkene, water, and protein impurities. Gas Chromatography (GC) results declared, an increase in hydrocarbon and hydrogen gas with an increase in temperature while reduced the generation of CO and CO2. Further, GC-MS analysis of pyrolytic oil revealed the presence of higher acids (19.46%), phenols (11.01%) ethers (11.12%) and ester (7.33%) which is a potent source of oxygenated compounds. Characterization results of biochar showed the presence of higher gross heating value (23.14 MJ kg), carbon content (62.66%), volatile matter (34.15%) and lower moisture (5.14%) and BET surface area (8.20 m2 g−1). Combining these results, it can be suggested that SS biomass has the potential to produce renewable fuel and chemicals, while biochar can be used for various applications.

Pyrolysis kinetics behaviour and thermal pyrolysis of Samanea saman seeds towards the production of renewable fuel

Dispatching rules have been studied from past decades, and it has concluded that these rules are composing vertebrae for various industrial scheduling applications Generally, it is a very tedious process to develop incipient dispatching rules in a given atmosphere by indulging and implementing dissimilar models under consideration and also to appraise them through extensive research For determining effectual dispatching rules, automatically, a pioneering approach is presented Proposed work addresses job shop scheduling problem (JSSP) NP hard in nature with the objective of minimizing mean flow time For achieving this, two latest dispatching rules have been introduced These latest rules will combine the process time and total work content of a job in queue under subsequent process Additive and alternative approaches have been taken for combining the rules For evaluating the performance of proposed dispatching rules, a rigorous study has been carried out against SPT rule, WINQ rule, SPT and WINQ rule, and the other best existing rules in common practice
