Mesoporous H-ZSM-5–carbon composites, prepared via tetrapropylammonium hydroxide (TPAOH) post treatment of H-ZSM-5 followed by deposition of pyrolytic carbon, have been used as the support for the preparation of Co-based Fischer–Tropsch catalysts. The resulting catalysts display an improved performance during Fischer–Tropsch synthesis (FTS), with higher activity, higher selectivity towards C5–C...

Different plastics recovered from a local urban solid waste plant were collected before landfilling, separated, and classified by families, i.e. polyethylene (PE), polypropylene (PP), high impact expanded polystyrene (HIPS EPS, respectively), terephthalate (PET), polyvinyl chloride (PVC). A systematic pyrolysis study was carried out to compare the different behavior registered in each plastic t...

Globally, nations are trying to address environmental issues such as global warming and climate change, along with the burden of declining fossil fuel reserves. Furthermore, countries aim reach zero carbon emissions within existing rising energy crisis. Therefore, bio-based alternative sustainable feedstocks being explored for producing bioenergy. One renewable resource is microalgae; these pho...

In this study, effects of TiO$_{2}$ and ZnO nanometal oxides on cellulose pyrolysis have been investigated. Both catalysts synthesized via hydrothermal method characterized by using different techniques. Catalytic catalyst-free experiments were carried out so as to identify the catalytic abilities nanoparticles. Catalyst-free at 500, 600, 700 °C in order determine optimal condition for it was f...

The pyrolytic process in preparing rayon into activated carbon fiber was studied by thermogravimetric analyses (TGA) and differential thermal gravimetry (DTG). For the promotion of the pyrolytic reaction and increment of carbonization yield, impregnants including phosphoric acid (PA) and its three ammonium salts, as well as the ammonium sulfate (AS), are added respectively for best resultant bo...
