JLDN- 1 is mainly used for purification and removal of NOx in diesel exhaust.
Characteristic:
1. High crystallinity, good hydrothermal stability, cation exchangeability, and adjustable acidity.
2. JLDN-1 zeolite can adsorb N2, CH4, and CO2 molecules with a critical diameter of not more than 3.8 Å.
3. Being used as a catalyst for the catalytic purification of NH3-SCR in diesel exhaust gas and methanol to olefins.
Frame type: Structure silicon-aluminum ratio (SiO2/Al2O3): 5-pure silicon; Channel characteristics: three-dimensional 8-element ring channel, pore diameter 0.38nm; Structure Si/Al ratio suitable for NOx catalyst: 8~35; Optimum Cu quantity: ~2-5%;
The most widely used SCR catalyst for denitrification of diesel engine thermal power plant is a vanadium-based catalyst, and its carrier is titanium dioxide. The high transforming rate window is between 300℃ and 400℃, suitable for denitrification at medium and high temperatures. It is not suitable for low-temperature flue gas treatment or diesel engine exhaust emission treatment under low operating load. Due to the wide range of diesel engine exhaust gas temperatures (150~600℃), it is necessary to find a catalyst with a wider temperature window in order to meet increasingly stringent emission standards. And now we have the equivalent product JLDN-1.

Luoyang Jalon Micro-nano New Materials Co., Ltd. JLPM series molecular sieves are mainly used for cryogenic drying of general industrial gases. The purification system in the air separation unit removes H2O and CO2, as well as natural gas and other hydrocarbon desulfurization (removal of H2S and mercaptans) and CO2.
It is worth mentioning that Yuntianhua United Commerce Co., Ltd. Company 52000 Nm3/Cryogenic air separation unit project. The design and manufacture method of the air separation unit by air, adsorber adopt vertical radial flow design, processing capacity of 311352 nm3 / h, 5.13 Bar (A) adsorption pressure, loading type my company JLPM3 efficient molecular sieve 92 tons, 107 tons of activated alumina, can ensure that the CO2 content in the air mean 1000 parts per million (2000 PPM) instantaneous equipment and stable operation, export CO2 molecular sieve < 0.1 PPM.
The fifth-generation high-performance molecular sieve JLPM1 is an advanced molecular sieve used in the pre-purification unit (APPU) of air separation equipment. Compared with previous generations, the fifth-generation high-performance molecular sieve JLPM1 has significantly improved CO2 adsorption capacity; the fifth-generation high-performance molecular sieve JLPM1 will bring multiple benefits to air separation designers and operators. For the design of the new air separation plant, the application of the fifth-generation high-performance molecular sieve JLPM1 can make the air separation occupy a smaller area, thereby reducing equipment investment and operating costs. The fifth-generation high-performance molecular sieve JLPM1 can also be used for the transformation of old equipment, which can reduce energy consumption or improveair separation processing capacity.
Oxygen molecular sieve is an important material to ensure the work of VPSA oxygen production equipment. This project is another successful case of our JLOX-103 lithium-type high-efficiency oxygen molecular sieve.
The 30000Nm3/h pressure swing adsorption (VPSA) oxygen production project of Zhuhai Yueyufeng Iron and Steel Co., Ltd., designed and built by CSSC Huanggang Precious Metals Co., Ltd., was successfully started up on June 27, 2019. As of May 29, 2020, the device has been operating stably for 11 months, and all indicators are better than the design indicators. It has been highly recognized and praised by customers, and has created a cumulative effect of 150 million yuan per year for the enterprise. At the same time, the project has realized intelligent oxygen production, mobile control and remote monitoring to guide production, helping to realize the green and intelligent promotion of the industry.
The project uses 4 sets of pressure swing adsorption (VPSA) oxygen generators in parallel. The single set of device is designed to produce 7500Nm3/h of oxygen and 80% oxygen purity. It is filled with our company (Luoyang Jalon Micro Nano New Materials Co., Ltd.) JLOX-103 lithium-type high-efficiency oxygen molecular sieve is 68 tons, the actual oxygen output reaches 7650Nm3/h, and the oxygen concentration is above 82.3%. The 4 sets of equipment in this project are filled with 272 tons of our JLOX-103 oxygen molecular sieve, with a total oxygen production of more than 30000Nm3/h.
Oxygen molecular sieve is an important material to ensure the operation of VPSA oxygen production equipment. This project is another successful case of our company’s JLOX-103 lithium-type high-efficiency oxygen molecular sieve.
