Which manufacturer produces the best catalytic cracking catalysts? ?

The products from Qilu Petrochemical Catalyst Factory are also good. You can take a look. You can look up the specific figures online.

It’s hard to say; the major catalyst manufacturers in China are three: Changling, Qilu, and Lanzhou. In fact, all the catalyst formulations come from the Institute of Petrochemistry; the appropriate catalyst is selected based on one’s own raw materials and desired product.

The key is your needs. If it is a specialty catalyst, it is necessary to follow RIPP’s advice; they have designated manufacturers (Zhoucun or Changling). In terms of quality alone, the catalysts in Lanzhou’s LB series have a smaller unit cell constant and thus better resistance to thermal degradation. Due to its newer production line, the Changling catalyst exhibits better sphericity as observed through microscopic analysis compared to the Zhoucun catalyst. Production in Zhoucun has been somewhat volatile due to factors such as staff adjustments and the establishment of Sinopec Catalyst Company, resulting in unstable products and quality.

I agree with what was said above; it mainly depends on your needs. There are many manufacturers capable of producing catalysts nowadays; the larger ones include Lanzhou Catalyst Factory, Zhoucun Catalyst Factory, and Changling Catalyst Factory, as well as some smaller catalyst factories in Zhejiang. At present, the vast majority of catalysts produced by catalyst manufacturers are developed by the Sinopec Research Institute (RIPP). Each catalyst is designed for specific purposes; it is impossible for a single catalyst to yield good liquid yields and product distributions for all types of feedstocks. For example, our plant uses LV-23 produced by Lanzhou Catalyst Factory; this catalyst is used in the catalytic cracking of heavy oil. It has a relatively hard structure, and when mixed with other catalysts, it can easily grind those other catalysts to pieces. At present, the product yield of our plant is good, and the distribution of the products is also satisfactory.

The major domestic catalyst manufacturers include Changleing, Qilu, and Lanzhou; the first two are part of Sinopec, while the latter is part of CNPC. When choosing a catalyst, it is necessary to do so based on the intended use; for example, there are catalysts designed to reduce olefins, those aimed at increasing diesel production, and catalysts that help protect against heavy metal contamination. After selecting the catalyst that meets one’s needs, one can choose from the three mentioned companies, taking into consideration factors such as price and physical properties, in order to ultimately pick the most suitable option.

If you have the freedom to make choices, I recommend using imported catalysts such as those from Akzo, Intehad, and Davidson (their names may have changed due to international mergers and acquisitions); these FCC catalysts, especially the additives used with them, have prices similar to those of domestic products, but they are far superior in quality to those produced by the three domestic manufacturers.

At present, the vast majority of catalysts produced by catalyst manufacturers are developed by the Sinopec Research Institute (RIPP); there are also imported catalysts, such as FCC catalysts from AkzoNobel, Intehad, and Davidson (whose names may have changed due to international mergers and acquisitions). You should consider your own needs when making a choice – it’s up to the users to decide which type is suitable for them. Currently, most domestic manufacturers use catalysts from those three companies, while imported catalysts are used less frequently; it’s not clear what advantages they might have

I suggest you obtain a small sample from three different suppliers and conduct experiments with them to make comparisons; the answer will then be clear. It’s not about determining which one is better or worse, but rather choosing the one that suits you best. :lol

Catalysts should be selected based on the characteristics of one’s oil products as well as the intended purpose of production; however, imported catalysts are not recommended. Although their quality is good, they present difficulties in terms of adaptability and subsequent maintenance. Lanzhou is currently doing very well, accounting for 45% of the domestic market share

Conventional FCC catalysts are more or less the same. However, each factory offers catalyst products tailored to different raw materials and production methods, so you can choose according to your own needs. Additionally, it should be noted that even if the catalyst formula remains unchanged, catalyst manufacturers can still produce defective products; therefore, it is necessary to consider the evaluations from other refineries after long-term use.
