4、Micro-chemical technology

5、Membrane materials and engineering

6、New membrane separation technology

7、Coalbed methane technology

8、Flue gas DeNOx technology


Research Progress:

1、Synthetic natural gas (SNG) technology

Successfully developed the methanation technologies for producing synthetic natural gas from coal syngas, coke oven gas, town gas and other various exhaust gas containing COx, and got a series of completely independent intellectual property rights of methanation industrial catalysts and high-efficiency methanation processes. This technology provides an efficient and clean way to use coal, which can release China's huge coal transport pressure and offer a reliable guarantee for long-term China's energy security.

2、De-O2 of Coal Bed Methane (D-O2TE)

Successfully developed De-O2 of Coal Bed Methane catalyst, and established the first set of demonstration unit for 300Nm3 / h De-O2 of Coal Bed Methane. Currently, the division is actively promoting the industrialization of this technology.

3、Selective catalytic reduction (SCR) of flue gas DeNOx technology

For NOx removal from the power plant flue gas, extruded honeycomb V2O5-WO3/TiO2 catalyst was prepared and tested at pilot-plant scale with real high-dust flue gases from a power plant achieving NOx conversions of around 93 %, with ammonia emissions lower than 3 ppm. The successful development of the new catalyst can satisfy the demand of SCR catalysts in China and push forward the proprietary manufacturing of the catalyst product.

4、Oilfield wastewater reuse technology

Developed catalytic aeration oxidation combined with manganese sand filtration process, the residue of Fe2+meets the requirements of polymer flooding. The project, saving more than 470,000 tons of water annually, has put into operation and improved oil recovery as well as avoided sewage discharge. And it has brought great economic and social benefits.

5、Microreactor system for production of ammonium biphosphate

The micro-chemical engineering system for the production of ammonium biphosphate has realized commercial operation at the Changling Catalyst Branch Co. of the SINOPEC and has run stably for 6 months in the commercial unit. This newly developed proprietary technology was designed for utilization in the production of ammonium biphosphate with a capacity of 8 to 10 tons per year. Unique features of the technology included smallness in equipment (Volumes of the micro-reactor, the micro-mixer and the micro-heat-exchangers all less than 6 liter), and fastness in heat removal and response. Moreover, the performance was continuous, easy to control, stable in operation, free from vibration, noise and exhaust gases, as well as high quality in product. Hence, the technology could realize enforcing of processes, safety in production, high efficiency and cleanliness in equipment.

6、Low-grade natural gas CO2 membrane separation technology

With capacity of 13.6 million NM3 low-grade natural gas membrane separation technology is the highest concentration of CO2 gas membrane plant in the world, which is the breakthrough of China’s membrane technology.

7、The development of light hydrocarbon gas membrane recovery process

Successfully developed new composite separation membranes for light hydrocarbon gas recovery and established the membrane separation pilot plant.
