What are the active components of a fluidized bed catalyst? Is the catalyst the same when used on petroleum and coal tar?
Petroleum-based and coal-based catalysts are different
Petroleum-based and coal-based catalysts are different
What is different about the master?
Coal-based ones generally have high density and complex composition; they use iron-group catalysts, with trivalent iron as the metal center and alumina as the carrier. Oil-based ones are typically produced through the hydrocracking of residue, using molybdenum-nickel metal centers with alumina as the carrier.
