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.

The invention discloses a production technology of ceramic with digital-controlled glazing. The production technology comprises the following steps of after a green body subjected to press forming isdried, surface glazes, patterns, various decorative and protective glazes and the like on the green body are directly printed by a digital printer. The technology can realize simultaneous printing ofthe surface glazes and the protective glazes with different effects on a same ceramic tile, can also perform whole glazing or local glazing to the ceramic tile and can also perform simultaneous printing of various colors, and then high-temperature firing is performed; digital printing glazing is accurate in positioning, the patterns are high in simulation degree, high in definition, strong in stereoscopic sensation and little in glazing amount, so that the production technology reduces waste of glazes, saves the energy, reduces emission, accords with the requirements for environmental protection, avoids the defects of cracking, deformation, glazed pinhole and the like of the green body caused by too much glazing quantity and moisture in the glazes, increases the high-grade rate of productsfrom a kiln, is particularly suitable for production of thin plates in a large specification, is high in production intelligence degree and reduces the manpower cost.

The invention provides an optical glass, the components of which are represented by weight percentage, containing: SiO 2 : 40~58%; TiO 2 : 18~32%; Na 2 O: 3-20%; K 2 O: 6~20%, of which TiO 2 / SiO 2 0.35 to 0.8. Through reasonable component design and proportioning, the optical glass of the present invention not only satisfies the expected refractive index and Abbe number, but also has excellent chemical stability, does not contain harmful components such as PbO, and meets the requirements of environmental protection.
