“…The enhanced catalytic efficacy of these nanoparticles, uniformly dispersed throughout the liquid fuel, permitted the proper amalgamation of air and fuel, resulting in an overall enhancement of the combustion process (Prabakaran et al, 2017;Yusuf et al, 2022a). Fuel quality, engine load, spray characteristics, and air-fuel ratio are all important elements in CO generation (Flamarz Al-Arkawazi, 2019;Hoang et al, 2018). CO emissions are created by the incomplete oxidation of carbon atoms in the combustion chamber's rich mixture sections at temperatures less than 1180°C (Deheri et al, 2020;Sarıdemir et al, 2024).…”

As a sustainable replacement for fossil fuels, biodiesel is a game-changer in the energy sector. There is no strategy to minimize biodiesel's significance as a sustainable, clean fuel source in light of the increasing climate change and environmental sustainability concerns. Nevertheless, conventional biodiesel production methods often run into problems like inadequate conversion efficiency and inappropriate fuel properties, which impede their broad adoption. The revolutionary potential of nanotechnology to circumvent these limitations and revolutionize biodiesel consumption and production is explored in this review paper. There are new possibilities for improving biodiesel output and engine efficiency, thanks to nanotechnology, which can alter matter at the atomic and molecular levels. Using nano-catalysts, nano-emulsification processes, and nano-encapsulation procedures, researchers have made significant advances in improving biodiesel qualities such as stability, combustion efficiency, and viscosity. Through a comprehensive analysis of current literature and research data, this article elucidates the crucial role of nanotechnology in advancing biodiesel technology. By shedding light on the most current advancements, challenges, and potential future outcomes in nano-based biodiesel manufacturing and consumption, this review hopes to add to the growing corpus of knowledge in the field and inspire additional innovation. In conclusion, there is great hope for a sustainable energy future, increased economic growth, and reduced environmental impacts through the application of nanotechnology.

“…In this study, both process conditions were varied to analyze their effects on the performance of the CHP plant. The ambient temperature was varied from 15 to 35 °C, considering its changes during the day, night, and rainy season in Malaysia, while the AFR was varied at 12.5:1, 14.1:1, and 15.1:1 to indicate a rich, stoichiometric, and lean AFR, respectively [32]. The performance of the CHP plant was measured by the amount of power produced by the gas turbine that consumed the product from the combustion chamber.…”

“…According to Barraga ´n-Escando ´n et al [33], the stoichiometric mixture is at 14.1:1, where enough amount of air is provided to completely burn all the fuel in the combustion chamber. An AFR below the stoichiometric value (12.5:1) is considered a rich mixture, where the amount of fuel is higher compared to the airflow [32]. This state will produce more power and give less damage to the engine as it burns cooler.…”

Simulation of an Integrated Anaerobic Digestion and Combined Heat and Power System for Food Waste Utilization

Demand for renewable energy such as biogas is increasing because it is considered a clean and environmentally friendly source of energy and has the potential for minimizing carbon emissions. Biogas production through anaerobic digestion (AD) of organic materials is considered one of the most sustainable ways. It can be utilized directly or indirectly to generate heat, electricity, or mechanical energy for transportation. One of the most effective ways to use biogas is the combined heat and power (CHP) system, especially in combination with simulation software to facilitate the whole process without an actual experimental setup, easing the evaluation and analysis process. This study aims to develop an integrated model of AD for biogas production from food waste and CHP plants, through simulation using Aspen Plus software. The simulated results show that the developed process model can predict the heat and power produced from food waste feedstock.

“…Due to this rapidly increasing alternative Atmosphere 2021, 12, 478 2 of 9 motor vehicle population, estimates of its emission levels are required. The emissions from compressed natural gas fueled taxis and buses were measured using a portable emission measurement system (PEMS) [16] under actual driving conditions [17][18][19][20][21]. Nesamani estimated the emissions from on-road vehicles in Chennai using the International Vehicle Emission (IVE) model [22] that examined various mitigation options to reduce vehicular emissions [23,24].…”

Emissions from motor vehicles have gained the attention of government agencies. To alleviate air pollution and reduce the petroleum demand from vehicles in China, the policy of “oil to gas” was vigorously carried out. Qingdao began to promote the use of natural gas vehicles (NGVs) in 2003. By the end of 2016, there were 9460 natural gas (NG) taxis in Qingdao, which accounted for 80% of the total taxis. An understanding of policy implementation for emission reductions is required. Experiments to obtain the taxi driving conditions and local parameters were investigated and an international vehicle emissions (IVE) localization model was established. Combined with vehicle mass analysis system (VMAS) experiments, the IVE localization model was amended and included the taxi pollutant emission factors. The result indicates that annual total carbon monoxide (CO) emissions from actual taxis are 6411.87 t, carbureted hydrogen (HC) emissions are 124.85 t, nitrogen oxide (NOx) emissions are 1397.44 t and particulate matter (PM) emissions are 8.9 t. When the taxis are running on pure natural gas, the annual emissions of CO, HC, NOx and PM are 4942.3 t, 48.15 t, 1496.01 t and 5.13 t, respectively. Unregulated emissions of annual total formaldehydes, benzene, acetaldehyde, 1,3-butadience emissions from an actual taxi are 65.99 t, 4.68 t, 1.04 t and 8.83 t. When the taxi is running on pure natural gas, the above unregulated emissions are 12.11 t, 1.27 t, 1.5 t and 0.02 t, respectively.
