Title:
MICRO-INTERFACE ENHANCED WAX OIL HYDROGENATION REACTION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/186641
Kind Code:
A1
Abstract:
The present invention relates to a micro-interface enhanced wax oil hydrogenation reaction system and method, comprising: a liquid-phase feed unit, a gas-phase feed unit, a micro-interface generator, a fixed-bed reactor, and a separation tank. Compared with a traditional fixed-bed reactor, the present invention breaks the gas to form micro-bubbles on the micron scale, so that the micro-bubbles mix with wax oil to form an emulsion, to increase the interphase area of the gas-liquid two phases and achieve the effect of enhancing mass transfer in a lower preset range, and the pressure during the reaction can be reduced by 10-80% while ensuring the reaction efficiency; meanwhile, by greatly enhancing the mass transfer, the present invention can greatly reduce the gas-to-liquid ratio, which not only reduces the material consumption of the gas, but also reduces the energy consumption of subsequent gas circulation compression; moreover, the method provided by the invention is low in process severity, high in production safety, low in ton product cost and high in market competitiveness.
