Abstract

Utilization of crude palm oils (CPO) as biodiesel faces difficulty due to their high level of viscosity. Mixing crude eucalyptus oils (CEO) with CPO may reduce the viscosity due to the presence of aromatic compounds in CEO. The single droplet analysis was performed to determine the characteristics of mixing CPO with the CEO. The results showed that the addition of CEO decreased the viscosity due to the presence of intermolecular attractions, thereby leading to more active molecules in the CPO-CEO mixture. Furthermore, the aromatic compound in the CEO helped in decreasing the CPO flash point, while the aromatic compound in the triglyceride molecule weakens the bonds between molecules. The addition of CEO to CPO tends to reduce the ignition delay due to the presence of cineol content in the CEO, which weakens the van der Waals bond in CPO.

Abstract

One of the strong candidates for biodiesel is Crude Coconut Oil (CCO) but its high viscosity cannot be applied directly without treatment. Therefore, nanocarbon is added to reduce the viscosity of CCO. Nanocarbon is a natural material with semiconductor properties, a good heat conductor, and can attract other molecules. By adding nanocarbon, it is expected to reduce the viscosity of CCO. This study aimed to determine the combustion characteristics of droplets on CCO by adding nanocarbon by 1% and 5%. The method used was a true experiment with droplets, which dripped on the thermocouple with activation energy from the heater. The results showed that CCO burned 0.933s with a droplet diameter of 4.307mm, droplet diameter of 5.472 mm. By adding 5% nanocarbon to CCO, the CCO burned faster, more reactive, and the ignition was shorter than the pure CCO and 1% CCO.

Abstract

This study investigated the catalytic pyrolysis of polypropylene (PP) and low-density polyethylene (LDPE) using 10 wt.% red mud and 10 wt.% limestone catalysts in a batch reactor. The process was conducted at an operating temperature of 350°C with retention times of 30, 60, and 90 minutes. The effects of adding red mud and limestone catalysts on the yields of liquid, solid, and gas pyrolysis products were analyzed. The pyrolytic oil was further evaluated using droplet evaporation measurements, equipped with a K-type thermocouple and a CCD camera to monitor droplet evolution within an atmospheric chamber. The addition of catalysts enhanced the liquid product yield while reducing the solid yield. The catalytic pyrolysis successfully facilitated the isomerization of plastic polymers, breaking the carbon chains of PP with 10 wt.% red mud. Olefin content increased by up to 7.3% for both 10 wt.% red mud and 10 wt.% limestone. Furthermore, the evaporation rate constant of the catalytic pyrolysis oils improved by up to 8.3%. This study aims to provide new insights into utilizing local waste materials to enhance the quality of pyrolytic plastic products.
