Energies, Journal Year: 2024, Volume and Issue: 17(16), P. 4126 - 4126

Published: Aug. 19, 2024

In modern society where fossil fuel prices are increasing and environmental issues becoming more severe, biodiesel, as a new type of clean fuel, is receiving attention. Biodiesel has the advantages renewability, friendliness, good properties, demonstrating broad application prospects. However, use biodiesel also faces some challenges, such higher density kinematic viscosity, lower calorific value, etc. The nanoparticles in engines helps to achieve goal fuel. terms characteristics, increase cetane flash point improving combustion efficiency safety, but may affect combustion. can promote micro explosions secondary atomization improve cylinder pressure, heat release rate, brake thermal while reducing consumption. Nanoparticles reduce HC CO emissions, through oxygen reaction area, incomplete products. On contrary, CO2 emissions because better conditions oxidation reactions. For NOX temperature others emissions. Comparison shows that all offer varying degrees improvement engine performance provided by TiO2 significantly than other nanoparticles. future, synergistic effect multiple should be explored further achieving effects cannot achieved single nanoparticle.

Abstract This research examines the performance variables, combustion, and amounts of NOx, CO, HC, K emissions in a diesel engine, using blends hemp biodiesel oleic acid with conventional diesel. To obtain from oil acid, heterogeneous sulfonated camphor catalyst (CASU-AL) was used for transesterification esterification respectively. Several characterization tests were performed on CASU-AL such as acid-base titration method quantification sites, XRD analysis to determine areas carbonaceous material, images composition obtained SEM EDX, porosity characteristics surface properties assessed BET analysis. Constant operating conditions autogenous reactor temperature 200 °C, reaction time 23 min, quantity 0.033 % w. analyses applied CASU-AL, several mixtures made diesel, different biodiesels laboratory.

Study on the process parameters and mechanical properties of thermoplastic sandwich panels with a vacuum infusion method

Polymer Composites, Journal Year: 2025, Volume and Issue: unknown

Published: March 25, 2025

Abstract Thermoplastic glass fiber composites exhibit the advantageous characteristic of easy recyclability for both fibers and resin, which is beneficial to address challenges associated with recycling difficulties environmental pollution stemming from traditional thermosetting composite materials. This paper proposes first time preparation PMMA thermoplastic resin/glass (GF) + polyethylene terephthalate (PET) foam sandwich panels using a vacuum infusion process mixed resin polymethyl methacrylate (PMMA) methyl (MMA). Taking number‐average molecular weight, content, benzoyl peroxide (BPO) content as input variables, quadratic regression models flat compressive strength (FCS) lateral (LCS) plate are obtained by Box–Behnken experiment. The results show that weight has larger effect on compression panel. Using response surface methodology (RSM) prediction, it can be known when 1 × 10 5 , 18.2 wt%, BPO 0.52 mol%, N,N‐Dimethylaniline (DMA) 0.5 vacuum‐filled panel best performance. In comparison conventional epoxy sandwiches, FCS LCS sandwiches infused under optimal parameters have been enhanced 7.64% 7.83%, respectively. Highlights Vacuum method GF/PET/GF MMA binary liquid proposed time. effects number average PMMA, mechanical properties were investigated method. technological optimized.
