Effect of Butanol-Diesel Blends in a Compression Ignition Engineto Reduce Emission

The paper describes the study of the gasoline fraction hydrofining on the zeolite-containing alumina catalysts modified with variable valence metals, additives of phosphorus and a rare-earth element. In this work, the new zeolite-containing alumina catalysts were developed: NiO-MoO 3 -E-P-HZSM-HY-Al 2 O 3 , CoO-MoO 3 -E-P-HZSM-HY-Al 2 O 3 and CoO-WO 3 -E-P-Al 2 O 3 -ZSM, where E is a rare-earth element. The research was carried out under high-pressure at the flow installation with a fixed catalyst bed. The smallest residual sulfur content (0.0005%) is observed in hydrotreated gasoline on the catalyst CoO-WO 3 -E-P-HZSM-HY-Al 2 O 3 , which is 2-4 times lower than on the catalysts CoO-MoO 3 -E-P-HZSM-HY-Al 2 O 3 and NiO-MoO 3 -E-P-HZSM-HY-Al 2 O 3 and lower than is limited by the Euro-5 standard. When tested on the NiO-MoO 3 -E-P-HZSM-HY-Al 2 O 3 catalyst, the octane number of the gasoline as a result of hydrotreating increased to 88.6, which is significantly higher than on other catalysts. According to electron microscopy, the catalysts are highly dispersed, the components of the active phase metals are mainly in the oxidized state, forming clusters-associates on the surface. The structure, dispersion and state of the clusters are related to the nature of the catalyst components. The synthesized catalysts make it possible to produce high-octane low-sulfur gasoline that meets European standards.

“…Several studies have been reported on the performance, combustion and emission of diesel -n-butanol blends in CI engines with impressive outcomes [21][22][23][24][25]. A lot more research papers were published on the combustion behaviour of binary and ternary blend mixtures of butanol/biodiesel/ and diesel; and butanol/biodiesel/ and diesel fuels [26][27][28][29][30].…”

Aims: This study aims to analyze the impact of diesel-n-butanol fuel blends on the performance and emissions of a 4-stroke diesel engine, with an emphasis on assessing the efficiency and emissions improvements of the D95 blend through experimentation and simulation procedures. Study Design: Performance evaluation was conducted in compliance with SAE J1349 test standards, using a Tec-Quipment TD110-115 4-stroke engine running at 1500 rpm. The GT-Power simulation toolkit was also employed to analyze different loads, using the D95 diesel-n-butanol blend and conventional diesel fuel. Place and Duration of Study: The study was conducted over a span of 2 months at the Automotive Engineering Technology Workshop, Federal Polytechnic, Bauchi, Nigeria. Methodology: The study followed the SAE J1349 test protocol, utilizing a D95 diesel-n-butanol blend and conventional diesel fuel. Engine setup, performance, and emissions were assessed through experimental procedures and GT-Power simulations. Despite its lower calorific value, the D95 blend exhibited performance comparable to that of diesel fuel. Results: The combined findings from both experimental and simulation analyses provided insights into the effects of n-butanol-diesel blends on engine attributes, combustion, and emissions. However, simulated torque and brake power consistently exceeded experimental values as the engine load increased. While the D95 blend exhibited brake power comparable to that of diesel fuel, it also improved performance efficiency, fuel economy, and reduced emissions. Therefore, it is expected to promote sustainability and environmentally friendly fuel choices in the transportation sector. Conclusion: The synergy of experimental and simulation results offers valuable insights into the effects of the diesel-n-butanol blend on engine performance, emissions, and fuel efficiency, while also improving the power output potential and providing sustainable fuel options.
