Experimental Measurement and Correlations of High Pressure Density Data for potential Liquid Organic Hydrogen Carriers

Abstract

The high pressure density data of six substances which are potential liquid organic hydrogen carrier systems (LOHCs) (toluene and methylcyclohexane, N-ethylcarbazole and dodecahydro-N-ethylcarbazole, dibenzyltoluene and octadecahydro-dibenzyltoluene) have been measured within pressure range of (1 to 25) MPa within wide range of temperature varying from 293.15 K to 523.15 K. The experimental data were correlated as a function of temperature and pressure using Tait equation. The experimental data were compared with correlated data, resulting in absolute average deviation (AAD = 0.10 %), maximum deviation (MD = 0.30 %), and standard deviation (σ = 1.12 × 10−4 g·cm−3).
