Use micrographs to diagnose FCC operations
New analytical methods explore processing problems at the catalyst particle level
Catalyst plays a pivotal role in the
fluid catalytic cracking (FCC) operation and affect product
yields and quality. Several testing methods are used to
determine quantitative results such as physical and chemical
composition of FCC catalysts. But the data are averages and do
not represent the real state of the catalyst particles.
Emerging observation methods, such as micrographs, can detect
operational problems including high catalyst loss, calcium (Ca)
contamination, poor coke burning, etc., for FCC catalyst. Such
testing methods can be applied to identify FCC unit problems
and resolve these difficulties at the particle level.
