乌尔禾油砂组成分析

Analysis of the Composition of Urho's Oil Sands

新疆乌尔禾地区油砂储量比较丰富,对其进行组成及结构分析可为油砂分离工业化处理提供参考。本研究以仪器分析为主要手段,测定了油砂的组成及结构。结果表明,油砂含油率为6%~16%,含砂率为82%~92%,含水率较低,在0.5%~2.0%;提取沥青油中碳和氢元素质量分数总和为91%,硫元素质量分数较低,但氧元素质量分数(7%)相对较高,饱和分、芳香分、胶质、沥青质质量分数分别为40%、21%、27%、12%;油砂固相主要由黏土和砂粒组成,主要成分为SiO_2和Al_2O_3,油砂平均粒径为204μm。

The oil sands reserves in the Urho area of Xinjiang are relatively abundant.Therefore,it is necessary to analyze its composition and structure so as to provide references for the selection of industrial processing schemes for oil sand separation.In this paper,the composition and structure of oil sands are determined by means of instrumental analysis.The experimental results show that the oil content of oil sands is 6%~16%,the solid content is 82%~92% and the water content is between0.5%~2.0%.The sum of the contents of carbon and hydrogen in the extracted bitumen oil is 91%,the sulfur content is low,and the oxygen content is relatively high,which is 7%.The mass fractions of saturated fraction,aromatic content,colloid content,asphaltene content are 40%,21%,27% and 12%,respectively.The solid phase of oil sand is mainly composed of clay and sand.The main compositions are SiO2 and Al2O3,and the average diameter of oil sand is 204μm.
