From China to Vietnam: SCR Catalyst Partnership | AIREP


Release time:

Oct 26,2026

AIREP joined the environment chamber delegation to Vietnam, meeting MOST and NACENTECH in Hanoi: product localization, 13-year DeNOx experience, 3-step tech transfer.
From October 19–24, the China Environment Chamber of Commerce (CECC) organized a delegation of entrepreneurs for a themed visit to Vietnam, surveying local environmental market demand, industrial policies and industrial park infrastructure, and connecting Chinese environmental technologies and equipment with Vietnam's green development.

 

On the morning of October 20, the first stop was Hanoi: the delegation called on Vietnam's Ministry of Science and Technology and held a roundtable with the National Innovation Institute (NACENTECH). Shandong AIREP Environmental Protection Co., Ltd. joined the delegation as its SCR catalyst specialist, and General Manager Rong Weilong spoke in the exchange session.

 

From a firsthand witness of China's battle for clean air to a fellow traveler in Vietnam's green transition, AIREP wants to turn thirteen years of "trial-and-error experience" into Vietnam's "fewer detours."

01 Standing in Hanoi, Seeing Ourselves Ten Years Ago

 

Vietnam's GDP grew by more than 8% last year, and industrial parks, power, cement, steel and waste-to-energy are expanding fast. But rapid growth tends to bring environmental pressure first and talk of treatment later — a road China has walked, and one Vietnam, in all likelihood, will walk too.

 

The difference: latecomers don't have to step in the same potholes.

 

Vietnam has issued Resolution 57 setting the direction of green transition; the QCVN 19:2024 emission standard has taken effect with tighter NOx limits; and a green transition committee mechanism is in place. For Chinese environmental companies, this is a window of opportunity — and a window of responsibility.

 

"Standing in Hanoi, it all feels familiar," said Rong Weilong at the roundtable. That familiarity comes from China's thirteen-year campaign for cleaner air.

 

02 Thirteen Years, One Thing

 

"I'm Rong Weilong from AIREP Environmental Protection — Air Environmental Protection. The name itself is what we do."

 

For thirteen years, AIREP has done one thing: SCR catalysts.

 

From winters when smog made people afraid to open their windows, to a time when "lucid waters and lush mountains are invaluable assets" has become daily reality, AIREP has been both witness and participant in China's environmental turnaround: steel sintering, coking, cement kilns, glass furnaces, gas turbines, internal combustion engines, waste incineration, chemicals — in almost every Chinese industry that needs DeNOx, AIREP's catalysts are running.

 

That cross-industry field experience is exactly the "China experience" Vietnam needs most right now.

 

03 Turning "China Experience" into "Vietnam Capability"

 

The China experience cannot remain a story. At the meeting, Rong Weilong used three words to lay out three things AIREP can do right away.

 

Product: local adaptation, not copying. AIREP's SCR catalysts cover the full honeycomb / corrugated / plate series with a 200–500°C temperature window, built for high-sulfur, high-dust, low-load and frequent start-stop conditions. Against the tighter NOx limits of QCVN 19:2024, AIREP can adjust catalyst formulations to Vietnamese coal, raw materials and waste composition — local adaptation, not a copy of the Chinese recipe.

 

Experience: real-world conditions beat lab data. Over thirteen years, AIREP has retrofitted a large number of existing units. Those lessons "paid for in tuition" — handling high-sulfur flue gas, extending catalyst life under frequent start-stops — are precisely the capabilities that developing economies in their industrialization stage need most.

 

Cooperation: a three-step technology transfer path.

 

  1. Turnkey licensing of formulation and process: bringing the mature SCR catalyst technology package to Vietnam;
  2. A joint local pilot platform: verifying adaptability in Vietnam itself, cutting the cost of trial and error;
  3. Exploring joint-venture production: from "Made in China" to "Made in Vietnam," turning Chinese experience into Vietnam's own R&D, manufacturing and service capability.

04 Going Global as a System: AIREP as Part of China's Technology Matrix

 

The delegation was led by CECC President Li Qilin and covered Chinese companies in industrial waste gas, water treatment, solid waste and environmental equipment.

 

President Li Qilin noted at the roundtable that China's environmental industry has exceeded RMB 2 trillion for four consecutive years, and that green and low-carbon capability, operation services and digital enablement are exactly what Vietnam needs today.

 

In the open exchange, the two sides went through industrial waste gas and VOCs control, water technology and equipment, and green industrial park management, item by item. AIREP's accumulation in "catalysts + industrial DeNOx" became an important piece of the Chinese company matrix.

 

The Vietnamese side also made clear that it hopes to draw on Chinese experience to build a green technology demonstration and transfer center.

 

For AIREP, this means Vietnam is not "the next export market," but "the next technology cooperation market."

 

AIREP doesn't want to be a bystander — it wants to be Vietnam's technology partner in the green transition.

 

There are no shortcuts in environmental protection. But there is a shorter road: the potholes others have hit, latecomers need not hit again. Thirteen years of Chinese DeNOx experience can be the time cost of Vietnam's blue sky.

 

AIREP came out of China's smoggy days. Next, it wants to stand beside Vietnam's stacks.

 

Bluer skies in Vietnam. Faster growth, too.
