Problems solved by technology

The use of pyrolysis to process oil sands can reduce water consumption, but the operating cost is high, and there are problems such as large wear and tear on the reactor caused by solid particles, and the large-scale industrialization of the device cannot be realized. In addition, a large amount of solids are produced after extraction of hydrocarbon oil. Waste residue, cannot achieve comprehensive utilization

Embodiment 1

[0040] see figure 1 As shown, the present embodiment provides a method for producing hydrocarbon oil and ceramsite using oil-lubricating oil sands as a raw material, the method comprising the following steps:

[0041] Oil-lubricating oil sand raw ore mined on the surface or in shallow layers, with a bulk density of 0.65g / cm 3 , the water content is 3%, the oil content is about 15%, after proper drying and crushing, the particles with a particle size below 150 μm are screened, adding clean water, stirring in the reaction kettle, adding active agent, cross-linking agent and dispersant in sequence to produce a suspension, After stirring, add foaming agent to generate foam, then add polymerization agent and catalyst, and inject into mold before gel generation. Among them, the various material components are:

[0042] Active agent (acrylamide)

[0043] Cross-linking agent (N, N'-methylenebisacrylamide)

[0044] Dispersant (2,3,5-triphenyltetrazolium)

[0045] Foaming agent (po...

Embodiment 2

[0064] see figure 2 As shown, the present embodiment provides a method for producing hydrocarbon oil and ceramsite with water-wettable oil sand as a raw material, the method comprising the following steps:

[0065] The water-moistened oil sand raw ore mined on the surface or shallow layer is a mixture of asphalt, sand, rich ore clay and water, containing 3% to 6% of water, 6% to 20% of asphalt, and the balance is inorganic matter ( sand, minerals, clay, etc.), the porosity is about 35%. This type of oil sand is pulverized, and through the screening process to remove larger gravel and other sundries, inject fresh water, heat to 90°C, mix and stir, and after fully circulating and washing, the oil-water mixture enters the oil-water separation unit to separate the crude crude.

[0066] Part of the sewage (still containing a small amount of oil) after the crude oil is separated is reinjected and circulated, and the rest passes through a traditional sewage treatment unit. In this...

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...
