Method for extracting hydrocarbon oil from oil sand and producing ceramsite

Abstract

The invention provides a method for extracting hydrocarbon oil from oil sand and producing ceramic aggregates. The method mainly comprises the following steps of: mixing the oil sand with water, an activating agent, a crosslinking agent, a dispersing agent, a foaming agent, a polymerizer and a catalyst and forming into grains with grain diameter of 0.5-2cm; and heating the formed grains, performing dry distillation to obtain the hydrocarbon oil, sintering at the high temperature of 750-1,100 DEG C for 1-4 hours and cooling to obtain the ceramic aggregates. In the method, the density of the ceramic aggregates can be controlled to be 0.3-1.8g / cm<3> according to different proportions of additives. The ceramic aggregates can be used as a filler for a moving bed biofilm reactor to perform oil-containing sewage treatment and can also be used as a building material or a chemical product.

Description

technical field

[0001] The invention relates to a method for extracting hydrocarbon oil from oil sand and producing ceramsite, in particular to a combined process for producing hydrocarbon oil and ceramsite simultaneously by using oil sand as a raw material and producing hydrocarbon oil through dry distillation heat conversion. Background technique

[0002] Oil sand, also known as tar sand or tar sand, is a kind of sand or sandstone containing bitumen or tar, which belongs to unconventional petroleum resources. Oil sands bitumen and sand can be separated from oil sands. Oil sand bitumen is a kind of bituminous petroleum hydrocarbon mixture, which can be completely dissolved in carbon disulfide. The synthetic oil produced after oil sand bitumen modification can be used as raw material for the production of gasoline and diesel fuel in refineries; the remaining sand solids are mainly composed of Composed of quartz, clay, feldspar, dolomite, calcite and mica, they account for a...
