ИЗУЧЕНИЕ ПРОЦЕССА ПОЛУЧЕНИЯ ЖИРНЫХ СПИРТОВ ПУТЕМ ПАРЦИАЛЬНОЙ ГИДРОДЕОКСИГЕНАЦИИ БИОДИЗЕЛЯ И ОЛЕИНОВОЙ КИСЛОТЫ

The partial reduction of fatty acid derivatives into corresponding fatty alcohols was studied in static and continuous flow reactors. The experiments with a static reactor showed that obtaining the maximum yield of major products requires a fatty acid as an initial substrate. The experiments in a flow reactor allowed us to determine optimal conditions for the production of alcohols and waxes: temperatures in the range 280–330 °C and pressures from 3,5 to 5,3 MPa. A theoretical scheme of the partial reduction of fatty acids was proposed. The scheme takes into account the target products (fatty alcohols) and all oxygenated side products. A mathematical model describing the scheme was suggested. Rate constants for the main steps of the conversion of oleic acid were determined. The constants may be used to evaluate the distribution of products at various contact times.
