PKU PIONEER 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. PKU PIONEER's absorbent products are exported 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.

Efficient CO absorbent PU-1
PU-1 is a highly selective CuCl/molecular sieve absorbent loaded with Cu developed by PKU 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 PKU PIONEER have reached a leading level in the world; moreover, the product quality is stable, which provides a reliable basis for meeting the design requirements of PSA CO device.

Efficient oxygen making absorbent PU-8
PU-8 is a lithium-based oxygen-making absorbent developed independently by PKU 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 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 oxygen generating plant are raised effectively.

Efficient hydrogen 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 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 molecular sieve pores, thus lowering absorption capacity and adding to the diffusional limitation.
