Rapid pyrolysis of two types of aquatic biomass (blue-green algae and water hyacinth), and their blends with two coals (bituminous and anthracite) was carried out in a high-frequency furnace. Nitrogen conversions during rapid pyrolysis of the two biomass and the interactions between the biomass and coals on nitrogen conversions were investigated. Results show that little nitrogen retained in char after the biomass pyrolysis, and NH(3) yields were higher than HCN. During co-pyrolysis of biomass and coal, interactions between biomass and coal decreased char-N yields and increased volatile-N yields, but the total yields of NH(3)+HCN in volatile-N were decreased in which HCN formations were decreased consistently, while NH(3) formations were only decreased in the high-temperature range but promoted in the low-temperature range. Interactions between blue-green algae and coals are stronger than those between water hyacinth and coal, and interactions between biomass and bituminous are stronger than those between biomass and anthracite.
在高频炉中对两种水生生物质（蓝绿藻和水葫芦）及其与两种煤（烟煤和无烟煤）的混合物进行了快速热解，研究了两种生物质在快速热解过程中的氮转化以及生物质与煤之间在氮转化上的相互作用。结果表明，生物质热解后焦炭中氮的保留量很少，NH(3)产率高于 HCN。在生物质与煤的共热解过程中，生物质与煤之间的相互作用降低了焦中氮的产率，增加了挥发分中氮的产率，但 NH(3)+HCN 的总产率在挥发分中降低，其中 HCN 的形成持续降低，而 NH(3)的形成仅在高温范围内降低，而在低温范围内促进。蓝绿藻与煤之间的相互作用强于水葫芦与煤之间的相互作用，生物质与烟煤之间的相互作用强于生物质与无烟煤之间的相互作用。
