The aim of this work is to exploit the pyrolysis characteristics microalgae Botryococcus braunii (BB) with a medium pore framework zeolite (MCM-22) and its delaminated counterpart higher external surface area (ITQ-2) using pyrolysis-gas-chromatography-mass-spectrometry (Py-GC/MS) fixed-bed reactor. study evaluates effect synthesized zeolites that possess different size, shape acidity on promoti...

Catalytic conversion of pyrolysis vapor from biomass was performed over CeO2 catalysts to produce ketones. Thermogravimetric-gas chromatography/mass spectrometry (TG-GC/MS) and TG-MS were applied understand the distribution vapors various including rape straw, poplar, cypress bagasse. The favorable feedstock with high yield ketones other useful components screened out for directional ketonizati...

Electrocatalysts In article number 2200107, Hiroshi Yabu and co-workers, present carbon catalysts obtained by pyrolysis of biomass resources including cellulose nanofibers, blood meals vitamin B12 showing high oxygen reduction, evolution hydrogen catalytic activity, comparable to that rare metals.

Biomass was subjected to conventional and microwave pyrolysis, to determine the influence of each process on the yield and composition of the derived gas, oil and char products. The influence of pyrolysis temperature and heating rate for the conventional pyrolysis and the microwave power was investigated. Two major stages of gas release were observed during biomass pyrolysis, the first being CO...

In the framework of the active and regenerative cooling of hypersonic and space structures, a kinetic mechanism should be proposed to investigate numerically the fuel pyrolysis and the coke formation with a possible surface effect (catalytic reactions). This chemical mechanism should be suitable for Computational Fluid Dynamics approach (limited number of species and reaction). For this purpose...

Waste management of olive pomace is difficult because the high production amount and nonbiodegradable organic substances. Catalytic pyrolysis process one effective methods for (OP) obtaining valuable substances from it. Therefore, in this study, different types marble sludge were used as catalyst at 500°C temperature 40% dose. While K1, K2, K3 are sludges obtained physicochemical treatment trav...

The carbon nanostructure composed of an array of vertically aligned carbon nanotubes (CNTs) and a planar graphite layer (PGL) located at the top of the array has been obtained by the injection chemical vapor deposition method, realized using high temperature catalytic pyrolysis of xylene-ferrocene mixture. The carbon nature of the planar layer was identified using Auger electron spectroscopy. S...

The corn stover originated biochar was developed to catalyze and simplify the compositions of biocrude oil from cellulose pyrolysis. generation common species such as furans (anhydro)-sugars in pyrolysis weakened remarkably presence biochars, while formation phenol alkylphenols enhanced. hydrogen favored when presented. For example at temperature 600 °C ratio 3, about 78 vol% detected, increase...

Methanol Synthesis In article number 2204122, Javier Pérez-Ramírez and co-workers apply flame spray pyrolysis to design superior ZnZrOx catalysts for methanol synthesis from CO2. Synthesis-structure-performance relationships are established, revealing that zinc speciation location determine catalyst architecture, the nature of catalytic ensembles, corresponding reactivity.
