Abstract

The invention relates to the field of microreactors, and discloses a coiled tube microreactor and a microreactor system. The coiled tube microreactor contains a support tube (31) and a microchannel (32) arranged around the support tube (31). , at least two fluid redistribution members (341) are arranged inside the microchannel (32), and one of the fluid redistribution members (341) is arranged at the inlet (36) of the microchannel (32), The fluid redistribution member (341) is a cone structure that allows fluid to flow out of the cone tip and into the downstream of the microchannel (32). The invention can prolong the residence time of reactants in a limited reactor volume while ensuring the mixing effect of homogeneous or multiphase raw materials in the coil microreactor, thereby simultaneously improving the selectivity of products and the conversion rate of raw materials.

Description

technical field [0001] The invention relates to the field of microreactors, in particular to a coiled tube microreactor and a microreactor system. Background technique [0002] Microreactor has obvious advantages in many aspects due to its small characteristic size in space, such as large specific surface area, excellent mixing, mass and heat transfer effects, accurate control of reaction time, temperature and other conditions, as well as green, safe and efficient production, etc. . [0003] Microreactors have been used in many petrochemical systems, such as PAO synthesis, liquefied gas desulfurization, Fischer-Tropsch synthesis, and hydrogenation processes. Microreactors have unique advantages in strengthening the reaction process and have great potential for industrialization. [0004] A fundamental limitation in the development of new technologies using microreactors is that the reaction time must be controlled within a certain range. Due to its difficult processing, mi...
