Prospects for Conversion of Refinery Gas to High-Octane Oxygen-Containing Components of Motor Fuels

AbstractDue to the growing restrictions on the content of aromatic compounds by the European legislation in motor fuels and at the same time the need for higher quality fuels (minimizing the presence of contaminants and hazardous products to health), it has become necessary to increase processes that can maximize the number of octane in gasoline. This manuscript is aimed to provide current trends and processes related to isomerization, alkylation and etherification processes to improve gasolines as final product. Examples provided include the isomerization of light n-alkanes into iso-alkanes or the alkylation, in which the preferred olefin is the methylbutilene and i-butane to produce a high octane number gasoline. Currently, there are two main commercial processes for alkylation processes (hydrofluoric and sulfuric acid technologies). Other incoming suitable process is the etherification of iso-olefins to bio-ethers (the European Union have as a minimum target of biofuel content in fuels of 10% in 2020). The refiners are recently investing in the production of bio-ETBE (ethyl tertiary butyl ether) and other products as additives using bio-ethanol and olefins. Commercial and new potential catalysts for all these processes are currently being used and under investigation.

High Octane

The tightening environmental standards for motor fuels on the one hand and the rapid growth of high quality motor fuel consumption on the other hand poses the problem of refining to reduce the amount of aromatics and in particular benzene in commercial products. Currently recycling oil is essential to the overall petroleum refining complex. To increase the depth of processing, and most important for the production of high octane components of motor fuels meeting the Euro-5 requirements, different processing variants hydrotreated fractions, among which the most modern process is isomerization. And because of this isomerization – as a process of producing components of gasoline with a high octane number and a low aromatic content became widespread. This work is devoted to the research activity of the two catalyst systems containing zirconium in its composition, in the conversion of pentane-hexane fraction, which is the raw material of isomerization process in refineries. The study was conducted in a laboratory flow-type reactor with a fixed catalyst bed. Analysis of the gaseous and liquid products of transformation was performed by gas-liquid chromatography. On the basis of analysis of experimental data, we can conclude that the two systems studied most active catalyst in the isomerization of pentane-hexane fraction is a system based on zeolite. When used which is possible to obtain liquid products with a low content of unbranched alkanes and high in isoparaffins that have high octane numbers and are safe components of motor fuels from an environmental point of view.

High Octane

This paper investigates the problems of increasing the efficiency of technological installations of oil refineries, which produce high-octane and environmentally friendly motor fuels. We used methods of mathematical modeling and fuzzy mathematics to maximize the volume of gasoline produced and improve its quality indicators, taking into account the imposed restrictions. On the basis of a systematic approach, an effective methodology is created for the development of a package of models of interconnected plant units using available information of a different nature, including fuzzy information. The resulting package of models makes it possible to systematically simulate the work of the unit under study and to increase the efficiency of the facility by increasing the volume of manufactured target products and improving its quality indicators. There are presented results of the analysis and expert assessment of the catalytic reforming unit LG-35-11/300-95 and the choice of the optimal type of model for individual units. A scheme is being created for combining the developed models into a single package of models. On the basis of the proposed methodology, hybrid models are being developed that make it possible to determine the volume of produced catalyzate and its quality indicators.

High Octane

In work are studied development of new oxygen-containing high-octane fuel compositions. The short review of comparisons of the main indicators is presented. In this article is shown need of development of production of octane additives. Receiving high-octane gasolines with use of components of the fuels alternative oil, the solution of these questions can become use of alcohols as additives to traditional gasoline, and first of all the ethyl alcohol produced from renewable sources of raw materialsThe goal can be carried out by means of modeling of technological processes. Using a software package of "UnisimDesign" we will make modeling of process of receiving isoamyl alcohol. In a basis of universal system of modeling of "UnisimDesign" the general principles of calculations of material and thermal balances of technological schemes are underlain.On the calculated scheme 1 isoamyl alcohol which is used in the form of additive to motor fuels is emitted one target product. However contained in fusel oils butanol also has broad application. Butanol is applied as solvent to paints, he is a part of brake fluids, industrial detergents. But at allocation of a butanol we face a problem, fusel oils contain water and form azeotrope mixes. For the solution of this problem we suggest to enter into initial raw materials hexane, in the ratio 1:1. It will allow us to allocate besides isoamyl alcohol and butanol. Modeling of process of division of fusel oils I have shown a possibility of allocation of two demanded target products. The technological scheme of installation of division of fusel oils is provided in work. Constructive characteristics of the columned equipment are calculated, material and thermal balances of installation are.
