“…The experiment was performed at 655 °C and 37 bar pressure with a feed flow rate of 2.9 mL/min. It is reported that the coke formation reduced significantly (more than 13 times) in the presence of 300 ppm of diphenyl selenide in the fuel and for a test duration of 12 h. Sobkowiak et al have investigated the influence of tetralin and tetralone mixture as an additive on the coke propensity of JP-8 fuel under supercritical conditions. The study was carried out in a silica-coated tubular reactor at 675 °C and 38 bar pressure with a feed flow rate of 2.2 mL/min.…”

“…To simulate the actual scenario in a laboratory, different approaches were adopted by various researchers in designing the test rig for the experimental investigation. Some groups of scientists have used direct heating DC power systems (as shown in Figure a) to heat the reactor to the desired temperature. ,, The other groups ,, have used furnace heating systems as shown in Figure b. We believe that the furnace heating approach is justifiable if the objective is to estimate the fuel conversion and coking rate.…”

In this study, an in-depth analysis has been performed on various technoengineering aspects of hydrocarbon cracking under supercritical conditions toward developing an endothermic fuel. The paper is segregated into several sections with specific emphasis. The major areas covered in this work include physicochemical characteristics of different endothermic fuels, supercritical pyrolysis of hydrocarbon fuels, phenomena of coking, and its suppression from an application viewpoint. The influence of various parameters (e.g., temperature, pressure, catalysts, space−time, etc.) on fuel conversion, endothermicity, and coke propensity has been emphasized in detail. The typical value of endothermic heat sink capacity for different fuels consisting of C 8 to C 15 hydrocarbons ranges from 500 to 1150 kJ/kg over temperature and pressure ranges of 550−750 °C and 25−55 bar, respectively. The effectiveness of various additives/initiators in improving endothermicity has been screened for wide ranges of temperature and pressure. Physicochemical properties like distillation characteristics, hydrocarbon composition, °API gravity, and sulfur content of different hydrocarbon fuels are compared in a single window. Most of the findings are abridged meticulously with relevant tables and plots. Toward the end, we have highlighted the critical issues/challenges on the experimental findings and prospective.

“…It has been proved that 1,2,3,4-tetrahydronaphthalene can significantly delay the formation of carbonaceous materials in hydrocarbon fuels as a hydrogen donor. 14 Because adding 1,2,3,4-tetrahydronaphthalene and n-decane to exo-tetrahydrodicyclopentadiene can improve the thermal stability of exo-tetrahydrodicyclopentadiene and its fluidity, it is vital to study the properties of the ternary system and the three corresponding binary systems. There have also been many reports on n-decane and 1,2,3,4-tetrahydronaphthalene mixtures.…”

“…The temperature of the hydrocarbon fuel is higher than the cracking temperature of the carbon–carbon bond when the aircraft cruises at a hypersonic speed, which may lead to some safety problems such as carbon deposition and blockage of pipelines. It has been proved that 1,2,3,4-tetrahydronaphthalene can significantly delay the formation of carbonaceous materials in hydrocarbon fuels as a hydrogen donor …”

The densities (ρ) and viscosities (η) of the ternary system exo-tetrahydrodicyclopentadiene + n-decane + 1,2,3,4-tetrahydronaphthalene and the three corresponding binary systems, exo-tetrahydrodicyclopentadiene + n-decane, 1,2,3,4-tetrahydronaphthalene + n-decane, and exo-tetrahydrodicyclopentadiene + 1,2,3,4-tetrahydronaphthalene, were measured at temperatures ranging from 293.15 to 333.15 K and at pressure p = 0.1 MPa. The densities and viscosities were determined using a vibrating-tube densimeter and an automatic microviscometer based on the rolling ball principle, respectively. The values of excess molar volumes (V m E) and the viscosity deviations (Δη) of every mixture were calculated with the measured data. The V m E and Δη values of the three binary systems and the ternary system were fitted to the Redlich–Kister equation and four semi-empirical equations, respectively. The V m E values are negative for the binary systems of exo-tetrahydrodicyclopentadiene + n-decane and 1,2,3,4-tetrahydronaphthalene + n-decane with the minimum at about x = 0.5, while the V m E value of the binary system exo-tetrahydrodicyclopentadiene + 1,2,3,4-tetrahydronaphthalene is positive with the maximum at x = 0.5. The Δη values of the three binary systems are negative over the entire concentration range. For the ternary system, the V m E values are positive when exo-tetrahydrodicyclopentadiene and 1,2,3,4-tetrahydronaphthalene are dominant. Otherwise, the V m E values turn out to be negative. The Δη values are negative over the entire concentration range. These phenomena can be explained by physical interactions and structural effects between components.

“…A promising approach to enhance the thermal stability of fuel is the use of thermal stabilizers. − Many previous studies on thermal stabilizers have focused on hydrogen donors (H donors), such as 1,2,3,4-tetrahydroquinoline (THQ), benzyl alcohol (BnOH), and tetralin (THN). H donors terminate the propagation of radicals produced upon thermal decomposition of fuel.…”

We investigated the thermal stability of exotetrahydrodicyclopentadiene (exo-THDCP, C 10 H 16 ) in the absence and presence of three additives, 3,4-dihydro-2H-1,4benzoxazine (Benzox), 1,2,3,4-tetrahydroquinoline (THQ), and 1,2,3,4-tetrahydroquinoxaline (THQox), which act as hydrogen donors (H donors). Conversion of exo-THDCP was slowed in the presence of the H donor. The order of the Hdonor effects on the decrease in the conversion of exo-THDCP was Benzox ≪ THQ < THQox. The H-donor-induced decrease in the conversion of exo-THDCP was smaller at higher temperature. In addition, the H-donor-induced decrease in the rate of
