基于流化床中快速生长的生物炭的观察，海带（日本海带），一种褐藻，预处理的热解过程的有效操作，以产生热解油。催化活性无机矿物质的去除和聚合海藻结构的软化通过化学处理进行，包括CaCl 2处理以分离有价值的和粘性的岩藻依聚糖和硫酸处理以去除催化活性矿物质。与未处理的海带热解油相比，硫酸预处理显着降低了无机元素，但没有显着影响热解油的性质。然而，未处理的海带产生显著大块的生物炭，这阻碍了热解的连续操作，用硫酸处理的海带不产生聚集的大颗粒生物炭，从而提供了开发可靠的连续热解工艺的手段。(C)2014爱思唯尔有限公司版权所有。
Based on observations of rapidly growing biochar in fluidization beds, kelp (Saccharina japonica), a species of brown algae, was pretreated for the efficient operation of pyrolysis processes to produce pyrolysis oils. The removal of catalytically active inorganic minerals and the softening of polymeric seaweed structures were performed by means of chemical treatments, including a CaCl2 treatment to isolate valuable and sticky fucoidan and a sulfuric acid treatment to remove catalytically active minerals. The sulfuric acid pretreatment significantly reduced the inorganic elements but did not significantly affect the properties of the pyrolysis oil compared to the non-treated kelp pyrolysis oil. Whereas the non-treated kelp produced significantly large chunks of biochar, which hindered the continuous operation of pyrolysis, the kelp treated with sulfuric acid did not produce aggregated large particles of biochar, thereby offering a means of developing reliable continuous pyrolysis processes.
