Accepted Answer

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

gratifying results.

Aimingat the current macro-reaction system that cannot effectively treat ultra-lowconcentration pollutan

-ts, Beijing University of Chemical Technology hasresearched and prepared a soft shell micro-reactor, which is

combined with the advanced oxidation technology Fention reaction to effectively treatlow-concentration dye

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

technology.

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-

generation printed circuit heat exchangerproducts and micro-environment system equipment, realized the

localization ofindustrialized micro-reactors, integrated catalyst-supported micro-channel reactors, Diffusion

bonded hybrid heatexchanger, and integratedmicro-channel reactor. It is not uncommon for channel

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

design.

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.
