For many years, capturing, storing or sequestering CO2 from concentrated emission sources
or from air has been a powerful technique for reducing atmospheric CO2. Moreover, the use …

Microporous zeolite-type materials, with crystalline porous structures formed by well-defined
channels and cages of molecular dimensions, have been widely employed as …

Zeolites are crystalline porous materials with important industrial applications, including

Advanced plastic waste recycling via pyrolysis and subsequent steam cracking of pyrolysis
oils has the potential to partly close the cycle between the petrochemical production of …

As the conversion of methanol to olefins (MTO) over a zeolite catalyst is conducted on acid
sites derived from framework aluminum (AlF), it is possible to enhance the catalytic …

The possibility to fulfill the increasing market demand and producers' needs in processing
crude oil, a cheap and universally available feedstock, to produce petrochemicals appears …

Steam cracking of hydrocarbons has been the major source of light olefins for more than half
a century. The recent studies have reported that ethylene and propylene can also be …

The direct conversion of crude oil to light olefins is considered one the cheapest and most
reliable sources of petrochemical primary feedstocks. Unlike in the past when refineries …
