Abstract

Pyrolysis is the heating of plastic waste at high temperatures with or without oxygen, producing oil, gas, and carbon residue. The use of catalysts in the pyrolysis process can accelerate the conversion of plastics, resulting in better-quality oil. This study aims to examine the potential of oil produced from the pyrolysis of Low-Density Polyethylene (LDPE) plastic with the addition of bentonite clay catalyst as an alternative fuel. The pyrolysis process was carried out experimentally at a temperature of 450 °C with a residence time of 60 minutes, and variations of catalyst composition of 0%, 5%, 10%, 15%, and 20% were tested to obtain the optimum condition. The composition that produced the highest oil yield was then tested at lower temperatures of 350°C and 400 °C with the same residence time. The optimum composition of bentonite clay catalyst was 15% at 450 °C. Without the catalyst (0% composition), the oil yield was 54.2%, which increased to 66% from a total feedstock of 500 g, and when compared to the plastic mass of 425 g, the oil yield reached 82.5%. The density of the oil was 0.766 g/ml, the viscosity was 1.53 cP, and the calorific value was 11302.33 cal/g. LDPE pyrolysis oil with bentonite clay catalyst showed characteristics closer to diesel fuel and kerosene. Thus, LDPE pyrolysis oil has the potential to be used as an alternative substitute for diesel fuel in energy applications.

Abstract

Refrigerant is an essential working fluid in refrigeration system. However, the use of synthetic refrigerant such as R-134a is now restricted due to its high Global Warming Potential (GWP) value. As an alternative, MC-134 as hydrocarbon refrigerant offers more environmentally friendly solution. This research aims to compare the performance of R-134a and MC-134 in a vapor compression refrigeration cycle system, as well as analyze the influence of expansion devices, namely capillary pipes and Thermostatic Expansion Valves (TEV). The test results show that for R-134a, increasing the length of the capillary pipe, increases the Coefficient of Performance (COP) by 20.83% due to decrease in compression work. In contrast, for MC-134, there is  decrease in COP by 3.35%. TEV provides the best performance with an increase in refrigeration effect of 6.05% and COP of 25.07%. However, TEV is not suitable for MC-134 because the low condensing pressure inhibits the phase change to liquid. In the use of 1.25 m and 1.5 m capillary pipes, MC-134 even has a higher COP of up to 16.65% compared to R-134a. Despite this, MC-134 still shows potential as a replacement for R-134a, with 30% of the mass capable of producing twice the refrigeration effect and 7.52% lower electric current consumption.

Abstract

Thermoelectric cooler (TEC) based on the Peltier effect offers a compact, silent, and environmentally friendly portable cooling solution. It can be used to preserve perishable food, medicine on remote area with limited or no electricity. This review explores experimental and theoretical findings from studies published between 2015 and 2025, with focus on portable beverage applications. Key material advances (average ZT ≈ 1–1.4) are traced, dominant thermal management bottlenecks are identified, and emerging optimization methods including artificial intelligence-assisted design are discussed. The system coefficients of performance (COPs) reported for one-stage beverage coolers have remained modest (0.2–0.9). However, recent prototypes have demonstrated the capability to achieve drink temperatures below 5 °C from 25 °C ambient within 30 minutes. These prototypes also show promising pathways for higher efficiency through hybrid photovoltaics, advanced heat sinks, and adaptive control.
