Performance Of Catalytic Pyrolysis Using Co-Mo/Ac-Zsm-5 With Microalgae

I. INTERNATIONAL TECHNOLOGY TRANSFER SYMPOSIUM, Samsun, Türkiye, 6 - 08 Mayıs 2024, ss.74, (Özet Bildiri)

This study examines the efficiency of catalytic pyrolysis in converting polypropylene

into biodiesel fuel using a hydrothermal reactor model TGYF-C. The Co-Mo/

AC-ZSM-5 catalyst was manufactured and a series of experiments were performed.

The conversion method yielded favorable results using the following analytical

techniques: bet, xrd, sem, edx, ft-ir,tga, icp, and nanoparticle size analyzer. The

combined action of Co-Mo and ZSM-5 zeolite, together with the large surface

area of activated carbon, enables effective decomposition and improvement of

pyrolysis vapors obtained from microalgae. Furthermore, the catalyst exhibits

exceptional stability after several reaction cycles. The experiments were divided

into two parts without using microalgae and with using microalgae (Chlorella

vulgaris). The experiments were conducted within a temperature range of 200°C

to 325°C (interval 25°C) with residence times of 30, 45, 60, 75, and 90 minutes. The

impact of temperature and residence time on the quantity and quality of biodiesel

was analyzed. The results indicate that higher temperatures and longer residence

times generally result in increased biodiesel production. But it is important to

optimize these factors to maintain the quality of the product. Samples of biodiesel

were tested using devices Grabner Instruments, GC-VUV and Oxygen Bomb

Calorimeter. Excellent results were obtained, such as higher heating value reach

to 40 kj/kg .This study offers valuable insights into the ideal operating conditions

for effectively converting polypropylene into biodiesel, thereby contributing to

sustainable waste management and the production of renewable fuel.
