The invention discloses a thermal pyrolysis method for Fischer-Tropsch synthesis reaction wax residue. The thermal pyrolysis method comprises the following steps of: (1), conveying the Fischer-Tropsch synthesis reaction wax residue to a horizontal rotary kiln for carrying out thermal pyrolysis to obtain pyrolysis oil gas and residue; (2), de-dusting and cooling the pyrolysis oil gas in sequence and enabling the de-dusted and cooled pyrolysis oil gas to enter a gas-liquid separator for carrying out gas-liquid separation to obtain non-condensable gas and liquid oil; (3), conveying the non-condensable gas to a heating furnace for carrying out combustion, wherein smoke gas generated by the combustion is used for transferring heat for the horizontal rotary kiln; (4), returning the residue to a charging port of the horizontal rotary kiln, enabling the residue to enter the horizontal rotary kiln and exhausting the residue out of the horizontal rotary kiln through an overflow port of the horizontal rotary kiln. According to the thermal pyrolysis method for Fischer-Tropsch synthesis reaction wax residue disclosed by the invention, heat transfer is directly carried out onto the high-temperature residue and the wax residue material through a back-mixing process, so that the pyrolysis efficiency can be greatly improved, and therefore, the wax residue reaches the pyrolysis temperature within a short time, the recovery rate of the effective components of the wax residue is as high as 85%, the waste is recycled, and the environment-friendly treatment requirements are satisfied.

The invention discloses a flake nano material for oil displacement. The present invention selects 3-glycidyl etheroxypropyl trimethoxysilane to modify hectorite nanoparticles to prepare sheet-shaped nanoparticles with epoxy groups on both sides, and then disperses the particles on the oil / water interface, using A hydrophobic compound with amino groups is used to modify one side of the particle hydrophobically, and sodium bisulfite is used to modify the other side of the particle hydrophilically to prepare an asymmetric sheet-shaped nanomaterial. After testing, the product has good dispersibility in simulated mineralized water; adding the product to the oil / water system can form an interfacial film with a certain strength, inhibit the fingering phenomenon during the displacement process, and improve the oil displacement effect; the product It has obvious viscosity-reducing effect on crude oil, and does not increase the difficulty of production fluid treatment.
