Description

Influence of electron irradiation on lignin destruction is studied. Hydrolyzed lignin and mixture of fatty acid triglycerides (FATG) have been irradiated by 8.5 MeV electrons. Comparative study of four variants of lignin destruction is carried out, they are pyrogenic distillation, post-radiation dry distillation, electron-beam distillation (EBD) and EBD at combined heating. The mechanism of lignin radiation-thermal transformation with guaiacol and creosol formation is considered. Lignin EBD is investigated depending on dose rate, absorbed dose, electroheating power and addition (FATG and chitin) content. It is pointed out, that lignin stimulates radiation-thermal conversion of FATG into low-viscosity diesel fuel. The conclusion is made, that lignin EBD at radiation and combined heating can be perspective effective method of vegetal polyphenols conversion into liquid phenols

Abstract (Russian)

Изучено влияние электронного излучения на деструкцию лигнина. Гидролизный сосновый лигнин и смесь триглицеридов жирных кислот (ТГЖК) облучали ускоренными электронами с энергией 8 МэВ. Проведено сравнительное изучение четырех режимов деструкции лигнина: сухой пирогенетической перегонки, пост-радиационной сухой перегонки, электронно-лучевой перегонки (ЭЛП) и ЭЛП при комбинированном нагреве. Рассмотрен механизм радиационно-термического превращения лигнина с образованием гваякола и креозола. Исследована ЭЛП лигнина в зависимости от мощности дозы, поглощенной дозы, мощности вспомогательного электронагрева и содержания примесей - ТГЖК и хитина. Отмечается, что лигнин стимулирует радиационно-термическую конверсию ТГЖК в маловязкое дизельное топливо. Сделан вывод, что ЭЛП лигнина при радиационном и комбинированном нагреве может быть перспективным эффективным методом конверсии растительных полифенолов в жидкие фенолы
