Abstract
本发明一种添加聚磷酸铵微胶囊和硼酸的生物质热解工艺；在聚磷酸铵微胶囊和硼酸存在的条件下，对生物质进行热解处理；本发明采用无污染的添加助剂的热解技术，用量少，无苛刻要求，改善热解各项性能明显，可明显提高热解效率。
Description
技术领域
本发明涉及一种添加聚磷酸铵微胶囊和硼酸的生物质热解工艺，是一项改进的生物质热解技术。
背景技术
生物质热裂解（又称热解或裂解），通常是指在无氧或低氧环境下，生物质被加热升温引起分子分解产生焦炭、可冷凝液体和气体产物的过程，是生物质能的一种重要利用形式。
生物质热裂解技术是世界上生物质能研究的前沿技术之一。该技术能以连续的工艺和工厂化的生产方式将生物质转化为高品质的生物油，还可以从中提取具有商业价值的化工产品。相比于常规的化石燃料，生物油因其所含的硫、氮等有害成分极其微小，是21世纪的绿色燃料。
生物质热解工艺可分为慢速、常规、快速或闪速。低温和长期的慢速裂解可以得到30%的焦炭产量；低于600℃的中等温度及中等反应速率（0.1～1℃/s）的常规热裂解可制成相同比例的气体、液体和固体产品；快速热裂解以10～200℃/s的升温速率，小于5s的停留时间；闪速热裂解相比于快速热裂解的反应条件更为严格，气体停留时间通常小于1s，升温速率大于103℃/s。
添加助剂的生物质快速热解是新近出现的技术，可以改进热解效率。但是添加聚磷酸铵微胶囊和硼酸的生物质热解工艺，目前尚未见相关的技术报道。
发明内容
本发明所要解决的技术问题是提供一种改进的生物质热解工艺，即添加聚磷酸铵微胶囊和硼酸的生物质热解工艺，其工艺技术容易实施，无污染，提高生物质热解的效果好，改善热解各项性能明显；本发明方法在在聚磷酸铵微胶囊和硼酸存在的条件下，对生物质进行热解处理。
对生物质处理时，聚磷酸铵微胶囊用量为生物质质量的0.4-0.8%，硼酸用量为生物质质量的0.2-0.6%。
对生物质处理时，温度为160-200℃，处理时间为4-10s。
聚磷酸铵微胶囊型号为Exolit IFR-23、Phas-chek P／30或Amgard Mc。
本发明中生物质为常规植物原料或植物废弃物,如木材或非木材（秸秆、稻草、杂草等）。
本发明的有益效果是:
(1)用量极少，工艺实施容易；
(2)改善热解各项性能，采用添加聚磷酸铵微胶囊和硼酸的生物质热解工艺，能提高热解率20-30%；
(3)采用的助剂有更高的热稳定性，改善热解的操作性，扩大其应用范围。
