Chemical catalysed recycling of polypropylene over a spent FCC catalyst and various commercial cracking catalysts using TGA

Kaolin and commercial fcc catalysts in the cracking of loads of polypropylene under refinary conditions

“…According to this mechanism, the reactivity and selectivity differ from paraffins to olefins and branched to linear hydrocarbons. Supposing a similar mechanism for catalytic pyrolysis of polymers, it is reasonable to expect that a modification in the structure of the polymer before pyrolysis catalyst can lead to further improved activity and selectivity (Dawood & Miura, 2002;Cardona & Corma, 2000;Angyal et al, 2007;Lin & Yang, 2008).…”

Attrition Resistant Fischer-Tropsch Catalysts Based on FCC Supports

“…FCC is a particularly well known and widely used process in the oil refineries to crack the heavy oil into smaller hydrocarbon chains used to produce gasoline and heating oil. FCC catalysts are typically composed of 5-40% zeolite Y dispersed in a matrix of synthetic silica-alumina, semi-synthetic clay derived gel or kaolin clay [21,22]. Worldwide, the production of this important class of catalysts is about 300,000…”

Production of valuable hydrocarbons by catalytic degradation of a mixture of post-consumer plastic waste in a fluidized-bed reactor

“…The solid remaining deposited on the catalyst after the catalytic degradation of the plastic was deemed ''residues'' and contained involatile products and coke. The amount and nature of the residues was determined by thermogravimetric analysis (TGA) [25]. A number of runs were repeated in order to check their reproducibility.…”
