Esterification of fatty acids of oil waste with i-butanol on soluble (p-toluenesulfonic acid) and solid acid catalysts was carried out. Based on the results of the research, the optimal conditions were substantiated, which make it possible to achieve 99–100% conversion in just 1.5–2 h of reaction. Dehydration of glucose in an aqueous medium (10% solution) was carried out on samples of H-forms of Purolite CT275 and KU-2-8 cations, which are characterized only by Brønsted acidity, with a yield of the main product (levulinic acid) up to 30%; the formation of 5-hydroxymethylfurfural was not observed. An analysis of modern scientific and patent literature in the field of obtaining valuable and practically important products and materials from hydrocarbon raw materials was carried out. The possibilities and prospects of using carbon materials as carriers of acid catalysts for the transformation of substances from renewable raw materials into widely used chemical products are shown. A formulation of composite preparations based on silica nanosols, a lignohumic component, natural polymers of pectin nature has been developed and regulations for their use for pre-sowing treatment of winter wheat seeds and foliar feeding have been defined. The conducted laboratory and vegetative studies confirm the effectiveness of the created preparations for pre-sowing treatment of Smuglyanka winter wheat seeds and Bohdana foliar treatments. The influence of aqueous solutions of inorganic and organic acids and alkalis on the course of the explosive autohydrolysis process in the temperature range of 160-200 °C with subsequent transformation of biomass into liquid products was studied. A laboratory facility was created for the study of catalytic thermochemical transformation of carbonaceous materials in the temperature range of 100-450 oC, which includes a reactor with a volume of 100 l, designed for loading solid raw materials weighing up to 65 kg.
