The application of elaborately designed magnetic catalysts has long been limited to ease their separation from the products only. In this paper, we for the first time employed a magnetic sulphonated poly(styrene-divinylbenzene) resin catalyst on a magnetically stabilized-bed (MSB) reactor to enhance the etherification of fluidized catalytic cracking (FCC) light gasoline, one of the most importa...

A Y zeolite-containing wide-pore composite was synthesized by in situ technique using polyvinyl alcohol and silica sol material. A fluid catalytic cracking (FCC) catalyst for maximizing gasoline yield was successfully developed with the modified composition. The as-made zeolite Y in its sodium form had a relative crystallinity of 52.9 % with a high silica/alumina amount of substance ratio of 5....

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...

For co-processing of bio-oil and conventional fossil feed in existing refinery fluid catalytic cracking (FCC) units, little attention has been paid to the increased aromatics basic nitrogen content associated with introduction how it affects FCC performance. In this contribution, effect blending two bio-oils obtained from different treatment wheat-straw pyrolysis vapors atmospheric residue was ...

The use of downer reactors (gas-solid co-current downward flow) in the Fluid Catalytic cracking (FCC) process for upgrading heavy crude oil into more valuable products has gradually become common last decades. This kind reactor is characterized by having homogeneous axial and radial flow structures, no back mixing, shorter residence times as compared with riser type. Although were introduced a ...

Fluid Catalytic Cracking (FCC) has traditionally been a key refining process in generating transportation fuels. Recently, the focus on FCC further intensified as it plays an increasingly important role generation of building blocks for petrochemical industry. Nickel is considered one most challenging contaminants and originates from Ni-containing compounds petroleum fractions, not only during ...
