摘要

木糖(D-xylose)是一种新型的甜味剂.其生产原料为农业植物纤维废料

如玉米芯、甘蔗渣、棉子壳、甘蔗髓、稻壳等.中国是农业大国

木糖的原料极其丰富

生产木糖是一个具有较高附加值的二次资源利用项目.国内已有数家企业投入生产

但许多技术问题尚未解决

制约了经济效益

其中结晶工序也是瓶颈之一.本文作为木糖生产新工艺的重要环节

研究了木糖连续冷却结晶过程

并根据结晶动力学的粒数衡算理论(Population Balance)及其连续稳态的动力学测定方法

探索了木糖的结晶动力学模型.国内外迄今尚无这方面的报道.1 粒数衡算理论

Abstract

Steady operation of crystallization of xylose was run successfully to simulate industrial process in a 5.0L experimental continuous cooling crystallizer with a clear liquor overflow and the crystal suspension density was acceptable for industry. The crystal size distribution(CSD) of products was analyzed with population balance

which set up the kinetics equation of crystallization of xylose from aqueous solution
