| "Formula" of the Project:
"Production of silicon dioxide and silicon-carbon composite - based on environmentally friendly technology for the recycling of agricultural waste".
Silicon dioxide (silica, SiO2, Lat.: «silica») - silicon oxide (IV). Colorless crystals with a melting point of + 1713 ... + 1728 ° C, which have a high hardness and strength. Physicochemical basis of the innovative process of heat treatment
Proceeding from the chemical and material composition of straw and husk of various cereals, it can be concluded that this material should be considered a natural silicone compound.
The technology of processing straw and husks involves obtaining a product in one stage of heat treatment.
The technological process of obtaining a product from straw and husk involves a number of operations connected with physical and chemical transformations. Straw and husk entering the reactor have a natural moisture content, however, there is no need for a preliminary drying operation.
The purpose of heat treatment in an oxidizing atmosphere in the general technological chain is the production of straw and husks of a de-precipitated residue representing an amorphized mixture of silica and carbon. In case of rapid heating in a vortex chamber to a final temperature not exceeding 800-1000 ° C, volatile products are released from the straw and husk and oxidized with the destruction of the structure of the material; due to the emission of volatile substances, the material is enriched with silica and carbon and the particles are ground. An additional contribution to the refinement of the particles ensures their mutual friction with respect to each other when moving in the vortex layer.
Technological novelty of the industrial process for the production of carbon-silica composites from straw and husks
The process is as follows.
Carbon-siliceous composite - a homogeneous mixture of amorphized silica and carbon (42-47% SiO2 and 50-57% C) - is obtained in the furnace by thermal treatment of raw materials in an oxidizing environment.
The technological process consists of the following stages:
• reception, storage and preparation of husks;
• Feeding the husk into the feed hopper;
• dosed supply of husk to the furnace;
• air supply to the combustion device;
• supply of natural gas to the combustion device for its heating;
• cooling of flue gases in the heat recovery unit;
• supply and heating of the network water in the heat recovery unit;
• precipitation of solid oxidation products (ash) in a baghouse dust collector;
• feeding of the caught product to the packaging machine;
• packing, storage and transportation of the product to the warehouse;
• evacuation of cleaned flue gases with a smoke exhaust from the dust collector to the chimney.
The module operates in a continuous mode with a continuous supply of straw (stems) and the output of the finished product.

| Competitive advantage of this technology.
Competing technologies for processing the husks with the receipt of these commodity products are not available in the world at present.
Explicit advantages of the new production (low cost, environmental cleanliness, reliable source of raw materials, flexibility of production) make it possible to oppose competitors to reduce prices for products, allow us to apply, in addition to pricing policy, an extensive way to involve new regions.
