Adsorbent/Catalyst

PIONEER has its own absorbent production base, which specializes in the production of various efficient absorbents and catalysts to be applied to the variable pressure absorption equipment. The production base is capable of producing 10,000 tons of absorbents each year, mainly including an efficient CO absorbent PU-1, an efficient oxygen making absorbent PU-8, an efficient deoxidant PU-5, an efficient hydrogenation catalyst PU-7, an efficient CO2 absorbent PU-10, and an efficient H2 purification absorbent PU-12, etc. PIONEER’s absorbent products are imported to dozens of countries, including India, Spain, The Republic of Belarus, Thailand, Myanmar, Indonesia, the Philippines, South Korea, Zambia, The Kingdom of Bahrain, and Congo.

Introduction to Main Absorbent

Efficient CO absorbent PU-1

PU-1 is a highly selective CuCl/molecular sieve absorbent loaded with Cu developed by PIONEER that has a great absorption capacity of CO, as the core and basis of PSA CO technology.

In virtue of years of experience in the absorbent production, intensified product quality management as well as continuous improvement and upgrading of absorbent production technology, the performance indexes of CO absorbent PU-1 produced by PIONEER has reached a leading level in the world; Moreover the product quality is stable, which provides a reliable basis for meeting the design requirements of PAS CO device.

Efficient oxygen making absorbent PU-8

PU-8 is a lithium-based oxygen making absorbent developed independently by PIONEER. In 1999, PU-8 absorbent was regarded as the “Key Project of China Torch Program” by the Ministry of Science and Technology of China, and received the certificate of 2001“National New Products Program”.

At normal temperatures and pressure, PU-8 has a higher absorption capacity of nitrogen than common absorbents, with a high separation coefficient. When the PU-8 oxygen making absorbent is applied to VPSA oxygen producing the device, the oxygen product yield coefficient will be high, and the feed air to be handled and the nitrogen to be absorbed will be substantially less than those to be handled and absorbed when a common oxygen making absorbent is used. The loads on the air blower and the vacuum pump will be decreased, so will power consumption for the oxygen generation. The economic indicators of the oxygen producing device are raised effectively.

Efficient oxygen making absorbent PU-12

PU-12 is a dedicated molecular sieve that has a special absorption capacity as the core of PSA-H2 technology. The composite molecular sieve made by traditional means (white powder with grain size 0.5-10.0 micrometer) is mixed into 15-20 percent of binder in line with the need of the industrial application, making grains that possess a certain mechanical strength and shape a certain form.  However, the introduced binder will reduce the content of effective molecular sieve and congest some of the molecular sieve pores, thus lowering absorption capacity and adding to the diffusional limitation.

To overcome the defects of binder applied to the traditional molecular sieve, PIONEER adopts a brand-new preparation technology, i.e. forming first and transformation later, to composite a new breed of the binderless molecular sieve. The inert binder is totally transformed to the molecular sieve components that have absorption capacity, thus clearing congestion in the pores of molecular sieve and substantially raising the amount and the rate of absorption. Compared with the traditional preparation technology, the absorption capacity of the binderless molecular sieve is raised by 15-20 percent, with an increase in the absorption rate by more than 30 percent. Meanwhile, with a greatly intensified strength, the molecular sieve will be absolutely able to resist the repeated washout by airflow in normal operating conditions and is especially applicable to the PSA-H2 process in the condition of high-pressure air source.
