Integrated Laser and Electron Microscopy Correlates Structure of Fluid Catalytic Cracking Particles to Bronsted Acidity

摘要

Fluid catalytic cracking (FCC) is the main industrial process used worldwide to convert crude oil fractions into fuels and important base chemicals, such as light olefins. This is achieved by using micron-sized spherical catalyst particles of complex composition. Zeolitic material, usually zeolite Y, is the main acidic active cracking ingredient and it is embedded in a matrix consisting of clay, silica, and alumina.
