Method for determining exploration exploitation value of oil shale

一种判断油页岩是否具有勘探开发价值的方法

Abstract

A method for determining exploration exploitation value of oil shale comprises: steps a, fragmenting oil shale and screening to obtain fragmented oil shale with certain granularity; step b, dipping fragment oil shale in an aqueous solution of hydrofluoric acid, stirring at a certain temperature for a certain period, performing hot filtering, and washing to neutralization with hot distilled water, and drying; c, dipping the oil shale processed in the step b in a catalyst solution, stirring at a certain temperature for a certain period, filtering at room temperature and performing vacuum drying; step d, dipping the oil shale processed in the step c in a co-catalyst solution, standing at a certain temperature for a certain period, filtering at room temperature, and naturally drying; and step e, performing normal-pressure destructive distillation on the oil shale processed in the step d at 300 DEG C-400 DEG C, collecting a liquid light fuel part and performing detection. By employing the method, good effect is achieved on improvement of oil yield and improvement of alkane content of the light fuel, and a relatively good basis is provided for determining whether oil shale possesses the exploration exploitation value.
一种判断油页岩是否具有勘探开发价值的方法,a.将油页岩破碎筛分至一定粒度;b.将破碎的油页岩浸入氢氟酸水溶液中,在一定温度下搅拌一定时间后,热过滤,热蒸馏水洗至中性,干燥;c.将经过步骤b处理的油页岩浸入催化剂溶液中,在一定温度下搅拌一定时间后,室温过滤,真空干燥;d.将经过步骤c处理的油页岩浸入催化剂助剂溶液中,在一定温度静置一定时间后,室温过滤,自然干燥;e.对经过步骤d处理的油页岩进行常压干馏,温度为300℃~400℃,收集液体轻质燃料部分并进行检测。本发明在提高产油率上和提高轻质燃料中烷烃含量上取得了良好的效果,对判断油页岩是否具有勘探开发价值提供了更好的依据。
