“…For Case 7, for example, the processing of 10.9 t/h H-Oil naphtha leads to a decrease in consumption of lift steam by 1.8 t/h. Additional improvement in the utilization of H-Oil naphtha could be achieved in future studies directed to the use of specialized additives and co-processing of bio-components as discussed in [62][63][64][65][66][67][68].…”

The vacuum residue hydrocracker naphtha (VRHN) is a chemically unstable product that during storage changes its colour and forms sediments after two weeks. It cannot be directly exported from the refinery without improving its chemical stability. In this research, the hydrotreatment of H-Oil naphtha with straight run naphtha in a commercial hydrotreater, its co-processing with fluid catalytic cracking (FCC) gasoline in a commercial Prime-G+ post-treater, and its co-processing with vacuum gas oil (VGO) in a commercial FCC unit were discussed. The hydrotreatment improves the chemical stability of H-Oil naphtha and reduces its sulphur content to 3 ppm. The Prime-G+ co-hydrotreating increases the H-Oil naphtha blending research octane number (RON) by 6 points and motor octane number (MON) by 9 points. The FCC co-cracking with VGO enhances the blending RON by 11.5 points and blending MON by 17.6 points. H-Oil naphtha conversion to gaseous products (C1–C4 hydrocarbons) in the commercial FCC unit was found to be 50%. The use of ZSM 5 containing catalyst additive during processing H-Oil naphtha showed to lead to FCC gasoline blending octane enhancement by 2 points. This enabled an increment of low octane number naphtha in the commodity premium near zero sulphur automotive gasoline by 2.4 vol.% and substantial improvement of refinery margin. The processing of H-Oil naphtha in the FCC unit leads also to energy saving as a result of an equivalent lift steam substitution in the FCC riser.

The development of oil refining in advanced nations is mostly focused on low-carbon fuel. Similar efforts are being made to improve the fuel efficiency of internal combustion engines, which will result in lower exhaust emissions. Furthermore, by assessing the indicated trends in engine building, it is important for fuel manufacturers to understand how the requirements for gasoline quality indicators will change, primarily for its knock resistance. The aim of the current comprehensive article is to study the state-of-the-art review emphasizing recent progress and prospects for producing high-octane gasoline fuel toward market development. The market for branded gasoline and multifunctional additives, involving friction modifiers, corrosion inhibitor components, as well as detergent components is presented. Furthermore, market development trends and quality requirements for motor gasoline, involving antiknocking characteristics and gasoline oxygenated compounds as additives, are exhibited. Besides, perspective gasoline engine technologies, including different types of engines, are declared. The formulation of effective gasoline surrogates is a challenging task due to advanced combustion strategies, engine design, and variable operating conditions in spark-ignition engines. The extensive development of direct injection and turbocharging technologies is constrained by the actual compression ratio of engines. Likewise, an increase in the knock resistance of the produced gasoline would further increase the compression ratio and efficiency of new internal combustion engines.

“…Knock in internal combustion gasoline engines is created by self-ignition of the unburnt blend of gasoline fuel and air ahead of the spark-ignited disperse flame forward and could give engine destruction if hard or permitted to take place through longterm work. 23 The happening of knock restricts the capability to run at optimum combustion behavior phasing with a raised compression ratio, gasoline engine maximization, reduction of harmful emissions, as well as other scenarios for enhancing performance. The octane rating is used to evaluate the resistance to self-ignition, which provides resistance to detonation during the framework of gasoline engines.…”

High concentrations of isoolefinic hydrocarbons can adversely affect the physical, chemical, mechanical, and ecological characteristics of gasoline fuels. One of the solutions to reduce olefin contents is the utilization of the methoxylation process. The current paper declares a perspective toward a gasoline-component-first technique, revealing an innovative highoctane additive on the basis of isoolefinic components, like isohexene. The olefin content of isohexene was 94% volumetrically. This affected the chemical oxidation under atmospheric conditions. Several gasoline fuels and experimental facilities that match European and Russian requirements were used to execute the recent work. The objective of the methoxylation process is to enhance the chemical oxidation fuels to raise the portion of aliphatic hydrocarbon isomers, to decrease unwanted olefin content, as well as to generate high-octane motor ethers as gasoline octane boosters. The product can be defined as methyl ester of isohexene (MEIH). Various MEIH blends have been measured with other gasoline octane boosters and refinery products. The results proved that antidetonation properties of MEIH were higher than those of base gasolines, tertiary amyl methyl ether (TAME), and isohexene and approximately equal to that of methyl tertiary butyl ether (MTBE). Additionally, the results of the calculated MEIH mixing octane rating were from 104.3 to 131.5 for the research method and from 87.5 to 120.0 for the motor method. Likewise, the olefin content of MEIH was 74.2% when the methoxylation process was applied for isohexene. The oxygen content of MEIH was 3.3 wt %, with no oxygen content in the sample of isohexene. Those have been done thanks to the utilization of the methoxylation process of isohexene. Finally, MEIH provided an individual perspective as a liquid transportation fuel with merits over isohexene, in terms of antidetonation properties, olefin contents, as well as a distillation characteristic range.
