Why do we need FCC catalyst testing?

Fluidized Catalytic Cracking (FCC) technology has been (and still is) one of the most important conversion processes in refineries. The core of the FCC device is the catalyst itself, and research and development of FCC catalysts with stable activity is very important.

Before being used in an actual FCC device, fresh FCC catalysts need to be evaluated to predict the performance of the device, so that customers can make important decisions about the operation of the device.

Alfa Chemistry Catalysts provides customers with suitable candidate solutions for FCC catalyst testing. Whether for standalone catalysts or co-catalysts, hydrothermal effect and metal deposition are the two main factors that affect catalyst deactivation in commercial FCC installations. Therefore, it is of great significance to evaluate the potential of cleavage activity and yield selectivity.

  • To study the uncertain effects of introducing bio-oil into a catalytic cracking unit, the researchers used a micro-activity test (MAT) setting to compare the co-processing of dry-heat bio-oil, catalytic pyrolysis oil, and hydro-treated bio-oil. Experiments have shown that the concentration of bio-oil in the process of co-processing should be kept low to avoid the formation of high coke.

  • Researchers test the cracking performance of reference and metal-contaminated catalysts in the micro-activity test (MAT) unit. It is used to study the influence of iron and calcium metal organic pollutants deposited on fluid catalytic cracking (FCC) catalysts on the stability, activity and selectivity of the catalyst through cyclic deactivation treatment. Studies have found that iron pollution reduces catalyst activity through two different mechanisms. At low iron concentrations, the inactivation is mainly due to the direct poisoning of acidic sites, while at high iron concentrations, the inactivation is mainly due to pore blockage.
