1、Dedicated adsorbents for Pressure Swing Adsorption (PSA)
The property of the adsorbent directly influences the purity of product and the recovery rate and it is the assurance for the process long-time operation continuously and steadily. So it is the key technology for PSA gas purification.
（1）Great dynamic absorption capacity, high separation factor, and easy desorption.
（2）Complete in variety for different feed composition and product quality.
（3）Greater abrasion strength and compressive strength and chemical inertness to all the separation gas
（4）With the advanced non-binder and multi-calcination manufacturing techniques, the adsorbent is much better than the same kind of imported adsorbent in the performance indicators such as bulk density and is among the world leading level in this field.
2、PSA High performance dedicated sequencing valves
The high-performance dedicated sequencing valves is also called pneumatic program controlled valve or flat valve. It is one of the widely used valves in the PSA unit. It has the following characters:
h)Fast switching and operating flexibly and safely
i)On-line maintenance without removing from pipes
j)Stuffing box which adopts the wearable V-shaped self-tightening compensate seal ring has a long lifetime of sealing.
k)The spool adopts special structure and material has the advantages of souring-resistance, zero leakage, and long lifetime.
l)Low flow-resistance with stream-line shape valve body
m)Keep excellent sealing performance even in the condition of frequently switching (more than 300000 times per year).
n)For high-pressure difference and mass flow rate requirement process, balancing system is adopted to remove pressure difference before and after the valve. In this condition, common compressed air-driven valve can be used.
3、Catalysts for methanol cracking
The dysfunctional catalyst for methanol cracking producing hydrogen developed by our company is suitable for methanol cracking and methanol decomposition to produce hydrogen, especially suitable for users of the small to medium-sized hydrogen production.
The catalysts have excellent properties for methanol cracking and CO conversion. In the process of methanol conversion to hydrogen, methanol cracking and CO conversion take place in the same catalyst bed, which make the process greatly simplified and enhance operability at the same time. In addition, as it combines the endothermic methanol cracking and exothermic CO conversion together, this process takes the advantage of the heat of reaction and avoids the heat problems caused by the exothermic reaction thus reduce energy cost.
4、Catalysts for methanation
5、Catalysts of steam reforming of methane
Co-Mo hydrogenation catalyst
ZnO desulfurization catalyst
Natural gas steam reforming catalyst
High temperature (mid-temperature) shift catalyst
6、Catalysts of oil products hydro-processing and hydro-cracking
7、Special attemperation device for reforming gas steam generator
Temperature control valves for reforming gas steam generator: the valve locates at the tail of reforming gas steam generator, and adjusting reforming gas flow of the center tubes and the heat exchange tubes to control mixed gas outlet temperature. The valve adopts pneumatic control mechanism, has the advantages of convenient operation, flexible control, long service life, flexible tube sheet design, high safety, simple structure and is convenient for the maintenance.
