The steam cracking of hydrocarbons has been the major process for light olefins production
in recent decades. Recent studies have shown that a considerable amount of propylene and …

The growing demand for clean and efficient fuels in the world reflects the rapid growth in
automotive vehicles and more stringent environmental regulations. Hence, the refining …

Aiming at the acid modification and stabilization of ordered mesopores in HZSM-5
nanosheet (NS) zeolite for catalytic cracking, two kinds of Fe-modified NS zeolite catalysts …

In this work, n-octane has been selected to represent the alkane content in the naphtha for
the catalytic cracking over Mn-ZSM-5 and Fe-ZSM-5 catalysts. Various characterization …

Catalytic cracking is one of the most important refining processes used in the petrochemical
industry, in which the highly active zeolite catalyst is the key to heavy oil catalytic cracking …

The increasing demand for base chemicals ie, ethylene and propylene, along with the
expected peak in gasoline and fuels demand, are stirring intense research into refineries to …

Abstract ZSM-5-and β-zeolite-containing two-layered hierarchical catalysts (2 LZ and 2 L-β)
were prepared using a template of malic acid and novel three-layered hierarchical catalysts …

The fluid catalytic cracking (FCC) process in petroleum refineries produces enormous
quantities of waste (spent) catalysts as solid waste. Due to stricter environmental …

In response to address the climate crisis, there has been a growing focus on substituting
conventional refinery-derived products with those derived from biorefineries. The utilization …

Maximizing the production of petrochemicals from crude oil at the expense of fuels is among
the most important targets for refiners. In this conversion, catalyst composition and …
