Natural aluminosilicates for catalytic depolymerization of polyethylene to produce liquid fuel-grade hydrocarbons and low olefins

Influence of modified mesoporous silica SBA‐15 on the flammability of intumescent high‐density polyethylene

“…In that respect, it is known that solid acids are able to catalyze the depolymerization of PE, with varying efficiencies. The product distribution into light olefins, waxes and coke depends on the reaction conditions, the type of acidity (Lewis or Brönsted) and the acid strength . Moreover, the effect of mesoporous silica fillers is also strongly dependent on the degradation mechanism of the polymer itself.…”

“…The product distribution into light olefins, waxes and coke depends on the reaction conditions, the type of acidity (Lewis or Brönsted) and the acid strength. [43] Moreover, the effect of mesoporous silica fillers is also strongly dependent on the degradation mechanism of the polymer itself. In a recent study, it was shown that doping the SBA-15 material with Al induces an increase of the LOI from 22 to 30 for polylactide (against 22 to 26 for the parent SBA-15).…”

Screening of catalytic activity of natural iron-bearing materials towards the Catalytic Wet Peroxide Oxidation of Orange II

“…Zeolite (Montanit300 ® , Montana Žalec, Slovenia) was provided by a collaborative Slovenian group, which previously evaluated the use of this material in the depolymerization of polyethylene [37]. This natural aluminosilicate is mostly composed of clinoptilolite (Na,K,-Ca) 6 4− and AlO 4 5− tetrahedrals that form rings, which in turn link up to form a three dimensional network [38].…”
