Effect of zeolitic nano-catalyst on biodiesel yield and biochar formation during the pyrolysis of tallow

This study investigates the effect of zeolite nano-catalyst on yield biodiesel and biochar formed from pyrolysis tallow (cow fat). Residual waste cow fat was pyrolyzed in a fixed-bed reactor laboratory-scale volume 2200 cm3, at operating temperatures 450, 500, 530, 580 °C heating rates 4, 5, 6 °C/min. The molecular composition analyzed using gas chromatography spectrograph (GC-MS). It observed that produced without catalyst mainly composed aromatic carboxylic acids, esters, alkanes, alkenes, while with consisted methyl pentanoic acid, heptanoic cyclo-olefins, 4,4-dimethylcyclohexene, butyl-cyclohexane, butyl-cyclopentane, 1-pentylcyclopentene. A 58% achieved when 1% used to pyrolyze an temperature 530 rate When zeolitic catalyst, decarboxylation promoted, higher 82.78 wt% achieved. Results this revealed although did not show incremental biodiesel, it favors biogas production formation.
