Creation of equipment and technology for inexpensive deep processing of sawdust in monosugar and further into biobutanol and protein-vitamin supplements for cattle feed
The production of biobutanol from cellulose-containing waste from agricultural processing and the forest industry Butanol is used as:
solvent in the paint and varnish industry, in the synthesis of many organic compounds, a component to traditional fuels or as an independent fuel for vehicles.
Also, this production solves the problem of recycling
The main scientific task is the destruction of cellulose to the state when enzymes begin to work. The use of mechanical processing is one of the most universal methods of influencing cellulose and wood materials. Since milling increases the availability of cellulose in wood. Improving the final results during machining is achieved due to preliminary irradiation (materials become more fragile and easily milled) and (or) the use of ozonolysis.
Creation and testing of an experimental installation for grinding sawdust During the work, calculations of the main parameters were carried out, and a preliminary design of the unit was performed. (Grinding of sawdust to particles size 0, 2 … 0, 5 μm). Work was carried out to study the effect of electro-mechanical effects (electrolysis) on sawdust, which showed an increase in the yield of sugars by 7-10%. To determine the magnitude of the pressing pressure of the work rolls in the experimental setup, studies were conducted on the basis of a laboratory setup. This was taken into account when designing a large plant. In collaboration with the Institute of Physical Chemistry of the Russian Academy of Sciences, a series of works is underway to destroy lignin by the ozonation method and to study the processes occurring in cellulose under mechanical action on sawdust.
