Experimental Study on the Combustion and Explosion Characteristics of Tributyl Phosphate and Kerosene Mixtures at Different Initial Pressures in High‐Temperature Environments

open access: yesEnergy Science &Engineering, EarlyView.
The explosion hazard of TBP and kerosene mixed vapor in the nuclear fuel reprocessing process is studied. The results enrich the explosion characteristics and explosion limits of TBP‐kerosene, and provide reference value and basis for the safety setting of the operation process and operating environment of nuclear fuel reprocessing plants ABSTRACT As ...

Techno‐Economic Analysis of Hydrocarbon‐CO2 Binary Mixtures in Heat Pump‐Based Thermal Energy Storages

open access: yesEnergy Technology, Volume 14, Issue 4, April 2026.
Heat‐pump charging of Carnot batteries with zeotropic large temperature glide CO2–alkane mixtures enables charging from ambient to ≈398.15 K with improved heat‐exchanger temperature matching at moderate pressure ratios. The highest COP occurs near xCO2 ≈ 0.15, whereas cost and throttling losses rise monotonically with CO2 content; butane isomers ...

Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

open access: yesAsia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling
