Abstract

In modern conditions of economic globalization, strengthening market relations and aggravated competition, the economic development of an enterprise directly depends on the introduction of innovations. The transition to an innovative path of development requires the enterprise to determine its readiness and assess the possibility of development and the further implementation of innovations. Modern trends in the production of conventional liquid fuels in Ukraine, in particular, analysis of the production of motor gasoline and primary oil refining in Ukraine, the share of motor gasoline produced in Ukraine in the total volume of gasoline used, the volume of bioethanol production by Ukrainian distillery factories have been analyzed in the article. An assessment of the resource production potential for the production of bioethanol in Ukraine has been carried out. Possibilities of bioethanol production in Ukraine at distilleries have been investigated. An analysis of molasses production in Ukraine and theoretically possible volumes of bioethanol production from molasses in Ukraine have been calculated. The scheme of key strategic priorities for the development of the food ethanol and bioethanol in Ukraine has been proposed. The advantages of using bioethanol in the gasoline-ethanol blends for vehicles have been noted, a SWOT analysis map for organizing the production of bioethanol at sugar beet processing plant and distilleries has been generated. The needs of Ukraine in the production of bioethanol have been calculated and, according to the results obtained, the volumes of bioethanol production have been predicted.

Abstract

The aim of the study was to evaluate the biochemical possibilities of converting waste lignocellulosic biomass to second generation bioethanol. Three substrates were used in the research: barley straw, rye straw and triticale straw. In the first stage of the research bacterial strains capable of converting waste biomass to produce sugars used to produce energy-useful ethanol were selected. Of the eight strains isolated the three with the highest potential were selected on the basis of activity index value. The raw materials were subjected to enzymatic hydrolysis using the simultaneous saccharifi cation and fermentation method (SSF process). Based on the conducted research, it was found that the examined waste biomass is suitable for the production of cellulosic bioethanol. As a result of distillation 10% and 15% (v/v) ethanol was obtained, depending on the strain and the type of raw material. It was demonstrated that the bacterial strain had a greater impact on the effectiveness of the process than the type of straw used.

Abstract

The article describes the results of combustion of a mixture of PCOME (purified cooking oil esters) and bioethanol in the compression ignition Perkins 1104C-44 engine. The engine was prepared for use with the classic type of fuel – diesel oil, not biofuels. That is why bioethanol was added to ester in tests so that the basic physicochemical properties of the obtained mixture were as close as possible to diesel fuel. Thanks to this, the use of such fuel in the future would not require reworking or adjusting the settings of selected elements of the engine power supply system. During this case study, the engine performance and heat release rate were analyzed. For comparison, tests were carried out while powering the engine with ester fuel, 10 and 20 per cent mixtures of bioethanol and PCOME. The speed and load characteristics for each fuel were determined. This article presents selected characteristics where the biggest differences were noticed.
