Pyrolytic Waste Plastic Oil and Its Diesel Blend: Fuel Characterization

The purpose of this paper is to study the applicability of thermal processed fuel oil (hereafter called waste plastic disposal, or WPD) of diesel engines using low-quality fuel oil. In the experiment, stability of engine operation and components of exhaust gas, such as NOx and COx, were inspected from basic and applicable points of view. This paper illustrates a new test and result of WPD oil applied to marine diesel engines. In recent years, efforts have to be made to develop an advanced technique for recycling waste plastics in order to use scrapped plastics as fuel for diesel engines. It is very important and necessary for us to cope with the increasing calorific value and to satisfy the growing need of environment protection. The experimental fuel oil is obtained by a mixing of diesel oil, WPD, and water.

Waste Plastic Oil

This study analyzes the performance of the diesel engine in terms of power, torque, specific fuel consumption, and thermal efficiency using diesel and pyrolysis oil. The waste plastic oil (WPO) used in this research was produced through a pyrolysis process using raw materials from Low-density Polyethylene (LDPE) mixed with diesel fuel in volume ratios WPO10, WPO20, WPO30, WPO40, and WPO50. In addition, a performance test was carried out on the single-cylinder diesel engine test bench. The results showed that performing the diesel engine with the addition of WPO increased the average power and torque by 5% and 3%, thereby producing a higher heating value. Furthermore, the concentration of WPO also reduces the level of specific fuel consumption to be more efficient, with a decrease in thermal efficiency. In conclusion, plastic waste pyrolysis oil is a promising alternative fuel applicable to a diesel engine.

Noise Vibration

Pyrolyzed waste plastic-based green fuel has been reported to be used as an alternate fuel for diesel engines. Some of the main challenges for implementing this in current automotive technology include evaluating engine performance, emission, noise vibration harshness (NVH), and knock characteristics of this fuel. This study focuses on the engine performance of poly-ethylene terephthalate (PET)-based waste plastic oil (WPO) at varying engine speed conditions. The pyrolysis of mixed-waste plastic was carried out at 300 °C in a fixed-bed reactor. Physicochemical properties such as viscosity, density, calorific value, sulfur, and research octane number (RON) of the plastic fuel and its blends with gasoline were analyzed using ASTM standard test methods. The WPO was blended with two different types of gasoline (RON88 and RON90) at 10, 20, and 30%, and was tested in a spark-ignition (SI) engine. The experimental results showed that different WPO–gasoline blends can be used in an SI engine without any engine modifications, and the performance indicators for different blends were found to be close to that of pure gasoline. The brake power and brake specific fuel consumption (BSFC) were found to be 4.1 kW and 0.309 kg/kW h, respectively. The 10% WPO and 90% RON90 blend produced optimal engine performance at 3500 rpm.

Calculation Results

В статье рассматриваются вопросы, связанные с анализом достоинств и недостатков различных видов альтернативных топлив. Эти топлива могут применяться на судах различного назначения со средне- и высокооборотными дизельными двигателями. Наиболее актуальной альтернативой для полной или частичной замены жидкого нефтяного топлива является биотопливо. Особое внимание уделено микроводорослям, темпы роста которых значительно выше, чем у выращиваемых наземных культур. Рассматриваются такие виды альтернативных топлив, как биодизель, биоэтанол, биогаз, растительное масло, пиролизное масло, биобутанол, диметиловый эфир. Показано, что для расчета количества выбросов загрязняющих веществ, выделяющихся при сжигании биотоплив в судовых ДВС, может подойти модель «черного ящика». Зная основные физико-химические свойства топлива (теплотворная способность, плотность, вязкость, содержание кислорода и др.), можно оценить расход топлива, определить выбросы углекислого газа. Представлены результаты расчетов выбросов загрязняющих веществ при сжигании биотоплив. В итоге все полученные результаты могут быть переведены в условные единицы и пересчитаны в эквиваленты выбрасываемых парниковых газов. The article discusses issues related to the analysis of the advantages and disadvantages of various types of alternative fuels. These fuels can be used on ships for various purposes equipped with MSD and HSD engines. Biofuels are the most relevant alternative for the complete or partial replacement of liquid fuel oil. Particular attention is paid to microalgae, the growth rate of which is much higher than that of grown terrestrial crops. These types of alternative fuels are considered as biodiesel, bioethanol, biogas, vegetable oil, pyrolysis oil, biobutanol, dimethyl ether, etc. It is shown that the “black box” model may be suitable for calculating the amount of pollutant emissions released during the combustion of biofuels in ship internal combustion engines. Knowing the basic physicochemical properties of fuel (calorific value, density, viscosity, oxygen content, etc.), it is possible to estimate fuel consumption and determine CO2emissions. The calculation results of pollutant emissions from biofuel combustion are presented. As a result, all the results obtained can be converted into conventional units and recalculated into the equivalents of the emitted greenhouse gases.

Direct Use

Utilising pyrolysis as a waste tyre processing technology has various economic and social advantages, along with the fact that it is an effective conversion method. Despite extensive research and a notable likelihood of success, this technology has not yet seen implementation in industrial and commercial settings. In this review, over 100 recent publications are reviewed and summarised to give attention to the current state of global tyre waste management, pyrolysis technology, and plastic waste conversion into liquid fuel. The study also investigated the suitability of pyrolysis oil for use in diesel engines and provided the results on diesel engine performance and emission characteristics. Most studies show that discarded tyres can yield 40–60% liquid oil with a calorific value of more than 40 MJ/kg, indicating that they are appropriate for direct use as boiler and furnace fuel. It has a low cetane index, as well as high viscosity, density, and aromatic content. According to diesel engine performance and emission studies, the power output and combustion efficiency of tyre pyrolysis oil are equivalent to diesel fuel, but engine emissions (NOX, CO, CO, SOX, and HC) are significantly greater in most circumstances. These findings indicate that tyre pyrolysis oil is not suitable for direct use in commercial automobile engines, but it can be utilised as a fuel additive or combined with other fuels.

Palm Kernel Shell

Burning fossil fuel like coal in power plants released carbon dioxide that had been absorbed millions of years ago. Unfortunately, excessive carbon dioxide emission had led to global warming. Malaysia, as one of the major exporters of palm oil, has abundant oil palm mill residues that could be converted into value-added product like biomass fuel briquettes. Fuel briquette with palm kernel shell and palm mesocarp fibre as its main ingredients showed satisfactory fuel characteristics and mechanical properties as a pure biomass fuel briquette. The effects of adding some coal of higher calorific value to the satisfactory biomass fuel briquette were focused in this study. Various coal-biomass fuel blends were used, ranging from 0wt% coal to 50wt% coal. The fuel properties and mechanical properties of pure biomass briquette and briquettes with different amount of coal added were compared experimentally. From the fuel properties tests, it was found that as the coal content in the briquette was increased, the carbon content and calorific value increased. Mechanical property tests on the fuel briquettes showed a mixture of results, with some favored higher portion of coal in the briquette for better handling, transport and storage properties while some favored greater amount of biomass.
