Reactor capable of self-balancing pressures inside and outside lining pipe, and use method thereof

Abstract

The invention relates to a reactor capable of self-balancing the pressures inside and outside a lining pipe, and applications thereof, wherein the reactor comprises a pressure bearing shell, an inertliner, a liner inlet sealing ring, a liner outlet sealing ring, a pressure balance valve and a self-protection pressure relief valve. According to the present invention, the pressure bearing shell bears the high pressure, the liner is made of the inert material so as not to participate in the reaction, sealing is formed between the inlet and the pressure bearing shell and between the outlet and the pressure bearing shell so as to protect the pressure bearing shell from being corroded by reactants and prevent the interference of the shell material on the reaction result, and the pressure balance valve and the self-protection pressure relief valve ensure the balance of the pressures inside and outside the liner during the pressure increasing and pressure decreasing process so as to avoid theliner breaking caused by pressure difference, and can provide the effect of the safety valve in the case of the too high pressure of the current end or the clogging of the outlet; and the reactor canbe used at the temperature of room temperature to 800 DEG C under the pressure of 0 pa to 1313 Mpa, and has advantages of simple production, low cost, convenient installation and use, reliable data,corrosion resistance, high safety and the like.

Description

technical field [0001] The invention relates to a high-temperature, high-pressure multiphase reactor and a use method thereof, in particular to a high-temperature, high-pressure multiphase reactor with an inner liner to self-balance the internal and external pressure of the liner and a use method thereof. Background technique [0002] Gas-solid phase reaction is the most common and important type of reaction in heterogeneous catalysis, and the corresponding reaction devices are widely used. For gas-solid phase catalytic reactions, the most commonly used reaction tube material at this stage is mainly quartz glass, which is resistant to high temperature and chemically inert. Although there is no effect of the reaction tube on the catalytic reaction results, the material itself Very fragile, very easy to break, and can only be used for normal pressure reactions. High-pressure reactions are also extremely common in gas-solid phase reactions. For example, synthesis gas chemistry...

Problems solved by technology

Although this kind of reaction tube greatly reduces the tube wall effect compared with the tube without lining, it is found after long-term use that because the lower end of the quartz tube and the metal tube is not sealed, there is a dead volume of reaction gas between them, which often occurs in the crack. Side reactions, the corresponding products will still diffuse to the outlet due to the concentration gradient difference, which will inevitably affect the final product analysis results

Some companies have further improved and optimized this kind of reaction tube. By adding an inert gas purge in the dead volume area, the influence of the tube wall effect is completely eliminated, but this method greatly improves the gas path system on the one hand. On the other hand, the inert gas will dilute the component concentration of the reaction product, so the detection error of some products with low concentration will increase accordingly, and the repeatability of the data may even be reduced due to the uneven mixing of the diluent gas
