“…In the first batches of American motor gasolines, the antiknock index was about 65−70 conventional units; however, with the development of technologies for the production of high-octane components and additives, the average antiknock index of the gasoline pool increased and in 2017 amounted to 88.3, which is approximately equivalent to the value of RON 93. 103 Increasing the ON of motor gasoline has been and remains the main vector for the development of fuels for automotive vehicles with spark ignition engines, which allows significant progress in fuel economy and reduction of CO 2 emissions. A constant increase in the antiknock resistance of the fuel is ensured by the involvement of various highoctane hydrocarbon components (reforming products, isomerization, catalytic cracking, alkylation, etc.)…”

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.

The use of gasoline with appropriate octane number will affect directly to meet superfine engine performance and avoiding from knocking effect. Improvement of gasoline quality in fluid catalytic cracking process usually is achieved by replacement of new catalyst which needs higher production cost. This research work aimed to describe the alternative method for improving gasoline octane in catalytic cracking by means of feedstock modification using mixture of vacuum gasoil and few of palm’s triglyceride and oleic acid. The experimental work of cracking reaction was performed in a fluid-bed reactor of ACE unit using REY zeolite catalysts at temperature of 530 °C and catalyst-oil ratio of 5.5 g/g. The liquid product was analyzed by a gas chromatograph of simulated distillation to determine yields of gasoline, light cycle oil and bottom product continued by a gas chromatograph of detailed hydrocarbon analysis to obtain hydrocarbon composition and calculated research octane number of gasoline. Analysis of gaseous product was performed using a gas chromatograph of refinery gas analyzer to detect yields of dry gas and LPG, whereas coke deposited on spent catalyst was analyzed using the infra-red method. From the research work, it was found that feedstock prepared from vacuum gasoil added with 5 % refined bleached deodorized palm oil and oleic acid (9:1) had increased gasoline RON from 91.8 to 98.2. The improvement of gasoline octane was contributed by the presence of double-bond fatty acid that triggered promoting effect to aromatisation and hydrogen transfer reactions in the formation of more iso-paraffins, olefins and aromatics in gasoline.
