    • The invention relates to an oxidative thermochemical drying process for changing the hydrophilic and hydrophobic characteristics of organic substances, in particular naturally occurring organic substances, to prepare a new class of hydrophobic oleophilic products, and a new class of hydrophilic oleophilic ones. The process comprises moistening and heating the raw materials in a thermochemical convection apparatus or kiln equipped with a gas flow system, in an oxidizing medium for a predetermined period of time. The efficiency of the treatment can be improved by pretreatments of the raw materials, such as by boiling in water, by soaking in acidic or alkaline solution, by mechanically expanding, by adding volatile reagents and by freezing. One unique pretreatment with carbonate or bicarbonate of the raw materials results in hydrophilic oleophilic bi-functional products. The series of the hydrophobic oleophilic and hydrophilic oleophilic products made from different natural substances under various oxidative thermochemical drying processes have different characteristics and are low-cost, efficient, biodegradable, environmentally harmless and widely useful.
    • 本发明涉及一种氧化热化学干燥方法,用于改变有机物质,特别是天然存在的有机物质的亲水和疏水特性,以制备新类型的疏水亲油产物,以及一类亲水亲油的。 该方法包括在配备有气体流动系统的热化学对流装置或窑炉中在氧化介质中预定时间段对原料进行润湿和加热。 通过预处理原料,例如通过在水中沸腾,通过在酸性或碱性溶液中浸泡,通过机械膨胀,通过加入挥发性试剂和冷冻,可以改善处理效率。 用原料的碳酸盐或碳酸氢盐进行独特的预处理可以产生亲水的亲油双功能产物。 在各种氧化热化学干燥工艺下,由不同天然物质制成的疏水亲油亲水性亲油产物系列具有不同的特点,成本低,效率高,可生物降解,环保无害,广泛应用。
