The propylene production with 1-butanol co-feeding for methanol in relation to propylene process (MTP) at 440-490 ̊C temperature range and at 0.9-15 hr-1 WHSV range over H-ZSM-5 zeolite catalyst is assessed in a isothermal fixed-bed reactor. The feedings here are of: pure 1-butanol, pure methanol and a 1-butanol and methanol mixture. The effect of 1-butanol co-feeding on selectivity of propylene...

This study evaluates an integrated process for the production of platform chemicals and diesel miscible biofuels. An energy crop (Miscanthus) was treated hydrothermally to produce levulinic acid (LA). Temperatures ranging between 150 and 200 °C, sulfuric acid concentrations 1-5 wt.% and treatment times 1-12 h were applied to give different combined severity factors. Temperatures of 175 and 200 ...

Catalytic fast co-pyrolysis of sewage sludge and sawdust was performed using Py/GC-MS for pyrolytic product upgrades. Metal oxides (NiO MoO3) ZSM-5 catalysts had been introduced into single catalytic pyrolysis. The combination NiO + MoO3 in mixed metal (MMOs) modified with under a dual-catalyst different layouts. In the pyrolysis process, specifically promoted formation phenols, ketones, furans...

The modes of deactivation -and the extent to which their properties can be restored- two catalyst bodies used in cascade for bio-oil synthesis have been studied. These catalysts include a solid acid granulate (namely ZrO2/desilicated zeolite ZSM-5/attapulgite clay) employed ex-situ catalytic fast pyrolysis biomass, and base extrudate (K-exchanged USY/attapulgite subsequent upgrading. Post-morte...
