An incorporating innovation and new interactive technology into obtaining sustainable aviation fuels

Abstract

Today, the transport sector, involving aviation, is the main source of greenhouse gases (GHG). At the state level, countries are trying to abandon the utilization of traditional fuels in favor of alternative ones, including electricity, biofuels, hydrogen fuel, as well as liquefied natural gas. Nevertheless, for the aviation sector, the introduction of many of these alternative fuels is difficult. The most optimal in terms of technical, technological and economic indicators is the use of biofuels produced from by-products of the agricultural and food sectors. The current article displays an overview of existing and promising new technologies for the generation of sustainable aviation fuel (SAF) from a wide variety of raw materials, including oil and fat raw materials, vegetable raw materials, food production waste, and so on. The authors suggested technologies for the generation of sustainable aviation fuel from oil and fat and vegetable raw materials. In the process of refining oil and fat raw materials by transesterification, hydrodeoxygenation, isodeparaffinization and glycerolysis, a whole list of high-quality low-carbon products is formed, such as biokerosene according to the first technology. Biokerosene is a complex bioadditive for diesel fuels and some other bioproducts. As an alternative, a technology for processing lignocellulosic raw materials based on the processes of fast pyrolysis, delayed coking, and hydrocracking has been proposed. The biokerosene obtained using this technology will not meet the existing specifications and will need a certification procedure.
