PKU PIONEER originates the high and low consumption PSA-CO technology based on PU-1 adsorbent, achieving the efficient separation of CO from nitrogen, methane and other components, which is of great importance for the carbonyl synthesis industry. This technology won the Second Prize for National Technology Invention.

PKU PIONEEER has designed and constructed dozens of PSA-CO plants for the clients, and becomes the highest shares holder in market with the features including low cost of gas product, high purity, high yield, flexibility of feed gas, moderate operating conditions and easy load regulation , which brings much economic earning and market competitiveness to the user.

Wide Applications
PSA-CO technology is suitable for any CO-rich feed gas.

High Purity and Recovery
The high purity of CO products (up to 99.99%) and high recovery (80%-95%) ensure high-quality and low-cost CO gas product for downstream synthesis.

Ranking 1st in Market Share
PKU PIONEER builds most of the PSA-CO plants in China, and holds over 90% of market shares.

Patented Adsorbent
Patented PSA-CO adsorbent PU-1 is highly efficient for producing high-quality CO.

Technical Applications

PSA-CO technology of PKU PIONEER has been successfully applied in ethylene glycol, butyl alcohol, acetic acid, acetic anhydride, formic acid, oxalic acid, oxalacetate, dimethyl formamide, dimethyl carbonate, TDI and MDI.

PKU PIONEER builds most of the PSA-CO plants in the world, including the world's largest PSA plant cluster (20,000Nm3/h of O2 product, 20,000Nm3/h of CO product and 40,000Nm3/h of H2 product), the world's first plant for purifying CO and H2 from calcium carbide exhaust, and the world's first plant for separating CO from blast furnace gas . PKU PIONEER has absolute leading advantages over the others and become the leading one in CO PSA industry.

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.

Newly type of hydrogen oxygen gas generator has been used the most advanced technology(Its electrolytic voltage is DC 24V, and electrolytic current is DC 13A,which reduces power supply breakdown.

special features of hydrogen oxygen gas generator
1.energy-saving: consume water and electricity; electrolysis water into hydrogen and oxygen gases; use hydrogen and oxygen as source of flame replacing LPG, propane,acetylene fuel,natural gas or other fuel.
2.environmental-friendly and safe: output of hydrogen oxygen flame burning is only water vapor with on smell or no pollution.
3.five safety elements: automatic air switch, non-return valve, auto-pressure release valve,flashback arrestor, flame torch with anti-flashback device.
