The dynamic simulation of the continuous catalytic reforming process is great significance to performance prediction and optimization entire process. In this study, a 34-lumped mechanism model described by differential algebra was established based on actual conditions in China, an efficient solution method simultaneous equations proposed. First, differential–algebraic basic principles kinetics...

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...
