[chemical] Use Spherical Ammonia Synthesis Catalyst Science – The Oil Industry

HC Network Petrochemical News: Reduce raw material consumption is related to nitrogen gas companies a key factor in the survival and development, and rational selection and use of high performance scientific ammonia synthesis catalyst is to reduce gas consumption of raw materials is one important way. South of the company by the Institute of Wen County in Henan Province joint development and production of ammonia catalyst plant of A10-1QACQ (cobalt) spherical catalyst, more than a decade after the enterprise applications in a number of chemical fertilizer have made significant economic benefits. Former manager of Henan Province, Li Jingxuan fertilizer that spherical ammonia synthesis catalyst to help the fertilizer industry to achieve energy saving efficiency is a key measure.

According to Li Jingxuan introduced a catalyst for ammonia production and use from the roughly spherical shape up and distinguish the two types of non-spherical, compared with other amorphous catalyst, A10-1QACQ (cobalt)-based ammonia synthesis catalyst has ten spherical Advantages:

First, long service life. Because the catalyst formulation is unique not only the ball hard, high strength, uniform size and spherical, easily crushed, so a particularly long service life. Chase Products Company of Henan Province to use A10-1QACQ (cobalt)-type spherical ammonia synthesis catalyst has been 5 years, and now the catalytic activity is still good.

Second is the “live from the” low temperature, good low temperature activity. General A110 catalyst “live from the” temperature of 380 C, while the A10-1QACQ (cobalt)-based ammonia synthesis catalyst spherical initial “live from the” temperature of 340 C, after 5 years is still far from the living temperature of 375 C, to improve the net to create the conditions for ammonia.

Third is ammonia synthesis reactor with high yields. If you use a good catalyst synthesis reactor, its exports of gas in the ammonia content of 12% ~ 14%, the best catalyst for up to 16%. Users showed that: A10-1QACQ catalyst in use after 5 years, exports of ammonia synthesis reactor content was still 15.5% ~ 16%. In addition, from into (synthetic) tower circulating gas in the inert gas (CH4, Ar, etc.) components of view, the use of other amorphous catalyst, inert gas is 10% ~ 14%, while the use of spherical inert gas after the catalyst can reach 18% 20%, this indicator is currently the leading domestic and international level, so that the feed gas consumption significantly.

Fourth, ammonia synthesis tower resistance. Most factories use amorphous catalyst for the production time of 1 ~ 2 years, must stop maintenance replacement of the catalyst. The use of spherical catalyst was still less than 5 years after the resistance of 0.1MPa, activity almost unabated. Heilongjiang Ning County fertilizer plant 5 years ago to use other amorphous catalyst, almost a year to be replaced once after switch A10-1QACQ (cobalt) catalyst, activity of 4 years continuous use unabated.

Five is a good heat resistance. With General Catalyst as synthetic tower hot 530 C, its activity was significantly decreased, if the use of A10-1Q catalyst, especially with ACQ (cobalt)-type spherical ammonia synthesis catalyst, once the hot spot to reach or exceed 530 C, after technical treatment can still revert to 480 C ~ 490 C, its activity was almost unaffected, can continue to use.
