Current status of domestic and foreign micro-channel reactor industry
Current status of domestic and foreignmicro-channel reactor industry
In the early 1990s, the research of micro-chemical technology startedabroad. The United States，Germ-
any,Britain,France, Japan and other developedcountries have successively carried out research on micro-
chemical engineeringand technology. According to incomplete statistics, there are currently morethan 50
micro-chemical technology and equipment suppliers in the world, ofwhich Europe accounts for about 60%.
It can be seen from Figure 1 that eachmicro-reactor system has its own characteristics and represents the
current advanced level and development direction of microreactor design and manufacturing.
The micro-reactor module of Ehrfeld in Germanycan be easily disassembled and cleaned.
TheMini-lab micro-reaction system of Corning Corporation is a highly integratedmodular device that
includes functionalmodules such as mixing, reaction, andheat exchange. All modules are made of glass.
TheSiprocess micro-reactor system of Siemens is an integrated modular system. Itscharacteristic is that
each module is equipped with an electronic system formeasurement and control, making it easier and more
precise for people tocontrol the reaction process.
The Mainz Institute in Germany took thelead in developing an electrochemical micro-reactor for the
synthesis of methoxybenzaldehyde from p-methoxybenzylmethane.
TheMassachusetts Institute of Technology in the United States has developed amicro-filled reactor for
gas-liquid-solid three-phase catalytic reactions.
HullUniversity in the United Kingdom designed a T-shaped liquid-liquid-liquid phasemicro-reactor. The
biggest feature of this reactor is the use of electroosmosisto transport fluid.
TheT-shaped thin-walled micro-reactor designed and manufactured by theMassachusetts Institute of
Technology is a representative gas phase micro-reactor.
Domesticresearch on micro-reactors has been carried out for more than ten years. Thedesign and
manufacture of micro-reactors, the exploration of micromixingprinciples, gas phase reaction, liquid phase
reaction, nanoparticle preparationand other fields have been rapidly developed and have achieved remarkable
results. At present, the main research institutions of micro-reactiontechnology are Dalian University of
Technology, University of Science andTechnology of China, East China University of Science and Technology,
BeijingUniversity of Chemical Technology, etc.
TheChemical Machinery Research Institute of East China University of Science andTechnology produced a
plate for the methanol steam reforming hydrogen micro-reactor.
TheUniversity of Science and Technology of China has developed a ceramic micro-reactorusing a sintering
method and conducted an ethanol water vapor reforming micro-reactorexperiment, which has achieved

water. new method.
Theintroduction of zeolite and zeolite membrane into the micro-reactor by DalianUniversity of Technology
can realize the combination of multiple advantages ofzeolite catalysis, membrane catalysis and microreaction
Inaddition to universities and research institutes, a number of outstanding micro-reactormanufacturers
have also emerged in the domestic market. Take Hangzhou ShenshiEnergy Saving Technology Co., Ltd. as
an example, relying on various researchand development teams in cooperation with well-known domestic
universities, ZhejiangUniversity, Tsinghua University, China Jiliang University, Shanghai Instituteof Organic
Chemistry, Chinese Academy of Sciences, and Tianjin University,focusing on the development of chemical
processes and industrial continuityEquipment system, successfully developed and produced the third-
localization ofindustrialized micro-reactors, integrated catalyst-supported micro-channel reactors, Diffusion
reaction systems to be usedin industrial cases. Hangzhou Shenshi development of localized micro-reactors
is not only reflected in the equipment, as a new third-board listed company,after it has accumulated a strong
advantage in the field of equipment, it hasexpanded to the field of military products. It is worth looking
forward toHangzhou Shenshi performance in the micro-reactor industry in the future.
Relyingon a strong process R&D and fluid simulation team, combined with advancedmachining
capabilities, Heroic can provide customers with a complete set of micro-reaction systemengineering
development and design.
Bornout of Heroic, Microwell Technology has creatively developed RTB micro-reactors withrectangular
channel discs and cross-mixing channels based on precisionprocessing equipment based on fluid mechanics
Fromthe results, the micro-reactor has indeed promoted a large number ofpharmaceutical and chemical
companies to achieve a comprehensive upgrade ofprocess technology.
In2011, the Research Institute of Sinopec Nanhua Group introduced ahigh-throughput-microchannel
continuous flow reactor from Corning, USA, andsuccessfully developed new processes for nitration of
chlorobenzene and specialrubber additives. Jiangsu Yangnong Chemical Pesticide uses Hangzhou Shenshi
integrated micro-channel reactor device, which not only takes up a small space,but also increases the product
yield by 6-8%, saving more than 1 million energycosts every year.
In recent years, systematic researches onmicro-reactors have been conducted at home and abroad, and
breakthroughs havebeen made in key technologies such as micro-reactor design, manufacturing,integration,
and amplification. Micromixers, integrated micro-channel reactors,and micro-reactors have been developed.
Heater and other equipment, however,there are still some problems to be solved if the micro-reactor is to
trulyreplace the traditional reactor for actual production.
