“…According to experts, oil as a main source of raw materials for production of wide variety of products will be exhausted in the next 100 years 3 , 4 , therefore, it will lead to critical decreasing of production. The systematic changing to regenerated energy supplies can prevent an economic crisis and decrease consequences of reduction oil sources 5 . One of perspective direction of this changing is replacement diesel oil (or part of diesel oil) to biodiesel, which is can be created with plant raw materials 6 – 9 .…”

Process of grain drying is discussed by the authors, which is considered one of the preliminary stages in the technology of biodiesel production. The drying process has a number of disadvantages that affect the quality and cost of biodiesel fuel. The impossibility of uniform heating and maintaining the required temperature with minimal energy costs is considered one of the most important defects that deserve scientific research. The authors propose a method for changing the heating system and preheating raw materials, based on world experience. We carried out mathematical calculations, provided the change in the temperature field of the drying chamber over time, and we also performed industrial experiment. Based on our results we determined the optimal number of heating sources of raw materials, taking into account the dimensions of the drying chamber. The authors propose a technical solution with which a uniform temperature field can be obtained in the drying chamber. Thus, the uniformity of the chamber heating will be increased, and large operating costs associated with leakage of oil from the grains will be disappeared.

The article presents the results of work on the formation of a bioresource collection of berry plants of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy based on a variety testing area of forest berry plants and a collection of species of the Dendrological Garden named after R.I. Schroeder. The variety testing area includes berry plants of the genera Vaccinium (V. corymbosum – 8 species; V. angustifolium – 4 species; V. corymbosum × V. angustifolium – 3 species; V. oxycoccos – 2 species; V macrocarpon – 3 species; V. vitis-idaea – 4 species) and Rubus (R. arcticus – 9 species; R. chamaemorus – 1 species). Introduced berry plants with edible fruits from the 24 genera are mainly represented in the collection of the Dendrological Garden named after R.I. Schroeder: Actinidia (4 species), Amelanchier (5 species), Aronia (2 species), Berberis (2 edible species), Cornus (2 species), Crataegus (more than 10 species), Elaeagnus (2 species), Fragaria (2 species), Hippophae (1 species), Lonicera (1 edible species), Mahonia (1 species), Morus (2 species), Prunus (13 species), Ribes (4 species), Rosa (6 edible species), Rubus (6 species), Sambucus (1 edible species), Schisandra (1 species), Shepherdia (1 species), Sorbus (more than 10 more than 10 species and a number of cultivars and a number of cultivars), Vaccinium (wild forms of 5 species), more than 5 species), Vitis (3 species). All plants included in the bioresource collection have nutritional and medicinal value and are quite stable in growth, development and fructification in the Moscow microclimate. Work has begun on the creation of an in vitro genetic bank of economically valuable, rare and difficult to propagate species, varieties and forms of berry plants. The aim is to maintain a bioresource collection, preserve biological diversity and accelerate the cultivation of planting material with subsequent fruit production under conditions of import substitution.

Environmentally Friendly Diesel Fuel Obtained from Vegetable Raw Materials and Hydrocarbon Crude

Currently, the global issue for countries is the search for raw materials and the production of bioenergy within their country; bioenergy also includes biodiesel fuels. One of the most promising biodiesel fuels is the green diesel fuel produced by the hydrogenation of vegetable oils. Three methods have been proposed to obtain high-quality biodiesel and environmentally friendly diesel fuel: compounding green diesel with hydro-treated diesel fuel, compositions of the improved fuel «green diesel» with bio-additives, and two-component mixtures of environmentally friendly diesel fuel with bio-additives. Using these methods, it is possible to produce fuel for diesel engines with improved lubricating properties, the wear scar diameter is reduced to 232 microns, according to EN 590: 2009, this value standard is up to 460 microns. The optimal quantitative composition of three-component environmentally friendly diesel fuel with improved lubricity was established. The dependence of the change in the lubricating properties of environmentally friendly diesel fuel on the quantitative and qualitative composition are established. A mathematical equation describing the dependence of the change in the corrected wear spot on the amount of anti-wear additive in the green diesel fuel is derived. Three-component compositions of environmentally friendly diesel fuel make it possible to obtain fuel that meets the requirements of the EN 590: 2009 standard and to expand the resources for obtaining fuel, as well as to improve the environmental and operational characteristics of the fuel.
