A porous phosphate heterostructure (PPHs) formed by a layered zirconium(IV) phosphate expanded with silica galleries was prepared presenting a P/Zr molar ratio equal to 2 and a (Si + Zr)/P ratio equal to 3. This pillared zirconium phosphate heterostructure was used as a catalyst support for bi-functional catalysts based on noble metals (Pt or Pd) and molybdenum oxide containing a total metallic...

The catalytic pyrolysis of Laminaria japonica was carried out over a hierarchical meso-MFI zeolite (Meso-MFI) and nanoporous Al-MCM-48 using pyrolysis gas chromatography/mass spectrometry (Py-GC/MS). The effect of the catalyst type on the product distribution and chemical composition of the bio-oil was examined using Py-GC/MS. The Meso-MFI exhibited a higher activity in deoxygenation and aromat...

Petroleum-derived monomers are the most common building blocks for ester-based thermosets. Bio-derived thermoset elastomers becoming viable alternatives to conventional Herein, we developed a biobased vitrimer-type using abundant and sustainable raspberry ketone as feedstock. We utilize create dynamic oxime chemistry crosslinked these through free radical polymerization with poly(ethylene glyco...

Ex-situ catalytic pyrolysis of pure glycerol to bio-aromatics over an un-modified H-ZSM-5 zeolite. • The conversion aromatics (BTX) with zeolite was investigated. An ex-situ approach used a separate and upgrading unit. A BTX peak carbon yield 28.1 ± 0.2% obtained. Catalyst performance for 5 reaction/regeneration cycles determined. Irreversible catalyst deactivation observed due dealumination th...

Proses interesterifikasi yang telah dilakukan menggunakan katalis homogen maupun heterogen perlu proses pemisahan di akhir reaksi. Minyak atsiri merupakan alternatif pilihan lebih efisien sebab tidak reaksi karena berfungsi sebagai antioksidan untuk biodiesel dan ramah lingkungan. Tujuan penelitian adalah mendapatkan pembuatan efektif yaitu dengan tahapan sedikit sehingga akan mengurangi biaya ...

Biomass has been offered as a sustainable replacement to fossil fuels since it can be converted into chemicals and liquid fuels. Recent years have seen surge in interest the feasibility of combining biomass rapid pyrolysis bio-oil catalytic upgrading produce biofuels. There would no progress this process without catalysts. Although achieved, problems with catalyst selectivity inactivation persi...
