摘要
对桦甸小颗粒页岩尾矿进行了工业分析和铝甑成分组成分析,表明小颗粒页岩中含挥发分27.48%,含油12.08%。通过反复试验,研制出适应于小颗粒页岩成型的多元复合粘结剂SN,并确定了成型较佳的工艺配比:复合粘结剂6%,水13%,压力25～30MP,在此工艺条件下,成型页岩的抗碎强度和热稳定性分别能达到90.4%、91.7%,能较好的满足工业化干馏工艺要求。
The small-size oil shale from Huadian was analyzed by Proximate analysis and Fisher Schrader assay.The results showed that it contained 27.48% volatile matter and the yield of shale oil was 12.08%.By repeated experiments,a multielement composite additive suitable for shaping of small-size oil shale was developed,which was named SN,and the optimum formulation（mass fraction）of shaping processing was SN 6%,water 13%,and pressure 25～30MP.Under these conditions,the shattering strength and the thermal stability were 90.4% and 91.7%,respectively.The shaped oil shale met the requirement for dry distillation in industry.
