摘　　要：介绍了以依兰粉末页岩作原料的页岩流化干流中试装置概况及试验流程,并对试验结果进行了分析。中试结果表明,中试装置页岩油产率为铝甑干馏法的90.15%,经冷凝回收系统及油泥处理后获得的页岩油收率为铝甑的82%;固体热载体流化干馏工艺所产页岩油较轻,337℃以前馏分大于80%。This paper deals with the research on the pulverized oil shale fluidized bed retorting at pilot plant scale(daily processing capacity of 50 tons of oil shale).The Chinese Yilan pulverized oil shale was used as the feedstock,and the oil shale is fed and pyrolyzed in a fluidized bed pyrolyzer.Pulverized oil shale fluidized bed retorting has the advantages of fully utilization of the mined oil shale(after crushing and grinding),with the shortest pyrolysis reaction time and highest retorting intensity in comparison with ordinary retorting technologies for processing lump oil shale.From 2004 to 2008,13 trial runs in total have been made for the pulverized oil shale fluidized bed retorting in the pilot plant.Many difficulties,especially the dusting and dedusting problems have been encountered and solved.Totally running hours of the plant reached 3 000 hours in the five years′ trial,with the longest continuous running of 192 hours in the end.It may be considered that this achievement provides a preliminary basis to scale up for a commercial plant design.
