The accumulation of plastic waste poses a major environmental challenge, while the conversion plastics into oil via pyrolysis holds promise as an alternative energy solution. Despite numerous investigations this area, none have focused on optimizing process parameters for higher yield and enhancing overall performance through suitable fuel modification. present study aims to optimize parameters, including heating rate (HR), temperature (PT), reaction time (RT), achieve (WPO) enhance by blending optimal quantities water. Fuel characterization properties measurement were conducted using Fourier Transform Infrared ASTM methods. WPO was blended with conventional diesel (CDF) different volume concentrations water (5%, 10%, 15%). metrices assessed under various engine conditions. findings indicate that optimum condition is HR 17.3 °C/min, PT 403 °C, RT 96.30 min, quality confirms its suitability source. metrics revealed has 5.4% lower brake-thermal efficiency than CDF, inclusion 10% in (WPO10W) enhances 11.5%. in-cylinder pressure net-heat release are 1.3% 12.9% respectively, WPO10W emulsion promotes efficient combustion. reduces oxides nitrogen, hydrocarbon, carbon monoxide emissions 21.2%, 9.8%, 22.2%, compared WPO.

Despite emulsification of water in-diesel can decrease harmful exhaust emissions, unstable emulsion result in formation free which accelerate metal corrosion the fuel delivery system a diesel engine. This study aimed to formulate and assess stability 5 vol% biodiesel (W5B5) investigate its effects towards copper corrosion. Stable W5B5 was successfully prepared with 3 polyglycerol polyricinoleate (PGPR). After 1200 h storage, remained stable, indicated by mean droplet diameter 627.6±7.5 nm, sedimentation index ∼3%, absence formation. Upon exposure copper, increased 2.7 times compared W5B5. Viscosity total acid number (TAN) values exposed 26% 270%, respectively, indicating enlargement droplets degradation during immersion. Corrosion rate decreased 92% between 240 5.5 3.0 higher biodiesel, respectively. Higher initial TAN than other fuels, attributed addition PGPR form stable water-fuel emulsion, influenced observed fuels. To minimize corrosive nature W5B5, future research should focus on developing formulation low acidity value comparable or even lower biodiesel. The contribution knowledge from yielded valuable insights into fuel, behaviour, impact emulsifier rates.

This paper reports the results of a study on significance inertization system configuration laboratory-scale fixed bed batch reactor with regard to yield pyrolysis oil and conversion. Two typical systems were investigated depending whether carrier gas (nitrogen in this study) was added from top or bottom reactor. Polypropylene (PP) packaging waste (100 g) used as model sample. A factorial experimental design adopted for one categorical parameter, arrangement parts system. All experiments conducted at 475 °C, flow rate 0.1 L/min reaction time 90 min. Statistical analysis processing showed that had remarkable impact yield, while its overall conversion negligible. When applying two observed methods inertization, average yields differed by 1.7% 1.8%, respectively. applied statistical treatments level 0.05, i.e., there only 5% chance incorrectly rejecting hypothesis equality arithmetic means when different applied. The explanation behavior is attributed temperature change inside reactor, which shows particular suffers local overheating middle part. Local part more pronounced case inerting bottom, leads greater excessive cracking volatile products compared mode thus formation non-condensable gases, reduction pyrolytic oil.
