Catalyst Technology Update

Improve FCC yields from contaminated feeds using boron-based nickel passivation

The drive to improve refinery margins leads to the processing of heavier, more contaminated crude and, consequently, an increasing amount of contaminants in fluid catalytic cracking (FCC) feedstock. Of these, nickel (Ni) deposits on the FCC catalyst and catalyzes dehydrogenation reactions, producing unwanted hydrogen (H2) and contaminant coke. These effects diminish the profitability and operability of the FCCU, creating strong demand for Ni passivation technology. Ni passivation is especially beneficial when the FCCU operates at the wet gas compressor (WGC), regenerator temperature limit, or air limit.

By alleviating these constraints, a substantial increase in profitability is possible by
