Summary: The burning of a mixture of diesel and natural gas shows potential in achieving better fuel economy and reduced emission. This study investigates the effects of blending natural gas with diesel fuel on ignition delay, heat production, and pollutant emission through numerical and experimental methods. A surrogate fuel with high accuracy is formulated to closely simulate the properties of diesel. The study also suggests an optimal mixture ratio for the dual fuel based on ignition time and acceptable pollutant emission in HCCI engines.

Summary: Hyperboosting is a phenomenon where the octane number of a blend is higher than both the base fuel and neat blendstock it was blended into. Blends exhibiting hyperboosting can improve engine efficiency. Experimentation with blending prenol into various base fuels revealed that certain prenol blends had lower reactivity than neat prenol or the base fuel, providing evidence of hyperboosting. Further data showed that aromatics may inhibit hyperboosting, while branched alkanes may enhance it. The structure-property relationship suggests that the double bond motif in prenol plays a role in hyperboosting.

Summary: Replacing fossil energy with renewable resources, such as fusel oil, is an effective way to reduce carbon emissions. By analyzing the characteristics of fusel alcohols and their interaction with diesel, the study found that adding 20% fusel oil with 6% water content can improve brake thermal efficiency by about 0.7%, reduce soot emission by up to 47.5%, and decrease NOx emissions by about 6.4%. The results suggest that fusel oil can be directly used in existing diesel engines without adversely affecting their performance.

Summary: The study examined the effects of blending ratio on ignition delay of mixtures of alcohol-to-jet (ATJ) fuel and conventional petroleum derived fuel. It was found that an increased volume fraction of ATJ resulted in longer, non-linearly increasing overall ignition delay. Additionally, first stage ignition delay and extended first stage ignition duration accounted for 15% and 85% of the increase in overall ignition delay respectively when compared to military aviation kerosene F-24.

Summary: In this study, a hybrid structure, MIL-53(Al)@MWCNT, was synthesized by combining MIL-53(Al) particles and -COOH functionalized multi-walled carbon nanotube (MWCNT). The hybrid structure was then embedded in a polyethersulfone (PES) polymer matrix to prepare a mixed matrix membrane (MMM) for CO2/CH4 and CO2/N2 separation. The addition of MWCNTs prevented MIL-53(Al) aggregation, improved membrane mechanical properties, and enhanced gas separation efficiency.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: The utilization of smart water in EOR operations has gained attention, but more research is needed to understand the complex mechanisms involved. This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.

Summary: In this study, high-performance solid catalysts based on phosphotungstic acid (HPW) supported on Zr-SBA-15 were synthesized and evaluated for the one-pot conversion of furfural (FUR) to γ-valerolactone (GVL). The catalysts were characterized using various techniques, and the ratio of HPW and Zr was found to significantly affect the selectivity of GVL. The HPW/Zr-SBA-15 (2-4-15) catalyst exhibited the highest GVL yield (83%) under optimized reaction conditions, and it was determined that a balance between Bronsted acid sites (BAS) and Lewis acid sites (LAS) was crucial for achieving higher catalytic performance. The reaction parameters and catalyst stability were also investigated.
