The fluid catalytic cracking (FCC) process is an alternative olefin production technology, with lower CO2 emission and higher energy-saving. This used for by almost 60% of the global feedstocks. Different parameters including operating conditions, feedstock properties, type catalyst can strongly affect activity product distribution. FCC catalysts contain zeolite as active component, a matrix, b...

For countries where catalytic cracking gasoline is the primary source, proposed technology consists in separating a benzene-rich fraction from order to be processed further together with reforming unit dedicated aromatics extraction. In this way, two benefits are obtained: as raw material for extraction and leftover that satisfies benzene content standards qualified product. It established use ...

The advancement of residual fluid catalytic cracking (RFCC) is significantly influenced by the development heavy metals passivation technology. Resids often include larger concentrations (Ni, V, and Fe) than gas oils, primarily in form porphyrin complexes salts organic acids. Under conditions, metals, especially Ni V residues oil deposit on catalyst induce adverse dehydrogenation reactions. cat...
