It is established that increasing the hydromodule reduces the content of lignin and inorganic components. At the same time, both the MCC outputs and its qualitative characteristics are declining. First of all, as the amount of cooking solution increases, the crystallinity index of the MCC decreases. Nanocellulose was obtained from MCC samples and its main physicochemical characteristics were studied. It is shown that in order to obtain nanocellulose it is necessary to take a high-purity MCC since the further destruction of amorphous components of cellulose occurs exclusively upon receipt of NC. It is proved that a NC with a structure with parallel planes 3 nm thick is obtained. A test batch (15 l) of ethyl esters used in the frying of sunflower oil was prepared according to a procedure that included transesterification with ethanol according to previously developed approaches on potassium ethylate, washing the ester layer with water and vacuum distillation of washed esters. The composition and properties of the experimental batch are determined, their compliance with the requirements of biodiesel standards is shown. It has been shown that vacuum distillation provides both an increase in the ester content to a level of about 99% and almost complete purification from mono-, di- and triglycerides. A comparison of the operation of the bench diesel VW 1.9TDI ALH engine on Euro-5 diesel fuel and its mixtures containing 20 and 50% vol. ethyl esters of the test batch. During the tests in the loading mode without special fuel supply settings, the preservation of the values of maximum torque and effective power during the transition from diesel to blended biodiesel fuels was demonstrated. For a mixture with an ester content of 50% vol. there was an increase in specific fuel efficiency by 12%. In the engine exhaust, CO was not actually recorded.
