水葫芦水热液化制备液体燃料的方法技术

本发明专利技术属于环境保护和新能源技术领域，具体涉及一种水葫芦水热液化制备液体燃料的方法。首先将水葫芦经破碎等简单处理后直接倒入高压反应釜内形成一定固液比的浆液，向反应釜内充入一定压力的惰性气体或还原性气体，搅拌升温至１８０～４５０℃，保持１～１２０ｍｉｎ，迅速冷却至室温，收集反应混合物，用有机溶剂对混合物进行萃取和抽提，分离并过滤有机相，除去有机溶剂即得到生物油。本方法以水葫芦作为原料，可大规模人工培养后不经干燥处理直接利用该方法进行液化处理，所以本发明专利技术提出的方法可作为一种获得环境友好可再生能源的途径，在资源化利用水葫芦残体的同时减轻水葫芦大量增殖带来的环境问题。

Method for preparing liquid fuel by hydrothermal liquefaction of water hyacinth

The invention belongs to the field of environmental protection and new energy technology, in particular to a method for preparing liquid fuel by hydrothermal liquefaction of water hyacinth. The water hyacinth by crushing and other simple processes directly into a solid-liquid ratio of the slurry to form a high-pressure reactor, inert gas to the reactor filled with certain pressure or reducing gas stirring, heating to 180 to 450 DEG C, 1 ~ 120min, rapid cooling to room temperature, collecting the reaction mixture by extraction and the mixture with organic solvent extraction, separation and filtration of the organic phase, the organic solvent is removed to obtain bio oil. The method uses the water hyacinth as raw material, can be large-scale artificial cultivation without drying after processing direct liquefaction treatment by this method, so the method of the invention can be used as a way to obtain environmental friendly renewable energy, reduce water hyacinth in utilization of water hyacinth residue and environmental problems brought by a large number of proliferation.
