In situ catalytic pyrolysis of lignocellulose using alkali-modified amorphous silica alumina [PDF]

Bioresource Technology, 2012
Canadian pinewood was pyrolyzed at 450 °C in an Infrared oven and the pyrolysis vapors were converted by passing through a catalyst bed at 450 °C. The catalysts studied were amorphous silica alumina (ASA) containing alkali metal or alkaline earth metal species including Na, K, Cs, Mg and Ca.

Conducting polymer wires in mesopore hosts [PDF]

, 1994
Nanometer-size conducting structures are of great interest in view of fundamental issues and potential applications. We explore the inclusion chemistry of conjugated polymers and graphite-like materials as a means to create such structures.

In situ performance of various metal doped catalysts in micro-pyrolysis and continuous fast pyrolysis

Fuel Processing Technology, 2016
Abstract Catalytic fast pyrolysis (CFP) of biomass is a promising route for the production of deoxygenated liquids suitable for further conversion to fuels and/or chemicals. In this work, CFP of pine wood in a micro-pyrolysis setup and a continuously operated bench-scale fast pyrolysis unit was performed to investigate the effect of catalyst type and

Microwave-assisted YBa2Cu3O7 precursors : a fast and reliable method towards chemical precursors for superconducting films [PDF]

, 2017
Highly stable, pure, and anhydrous organometallic YBa2Cu3O7- (YBCO) precursor solutions were prepared by dissolving commercial YBCO powder in acetone by trifluoroacetic anhydride (TFAA) or a mixture of TFAA with propionic acid for low fluorine precursors.

Ion mobility mass spectrometry of in situ generated biomass pyrolysis products

Journal of Analytical and Applied Pyrolysis, 2021
Abstract Lignocellulosic biomass is an abundant and renewable energy source that can be used as biofuel after physicochemical conversion, e.g. by fast pyrolysis. However, the chemical variations from wood and other biomass species affect this conversion.

Thermodynamic Analysis on In Situ Underground Pyrolysis of Tar-Rich Coal: Secondary Reactions

ACS Omega, 2023
To develop the in situ underground pyrolysis process of tar-rich coal more scientifically, the effect of temperature and pressure on the distribution of pyrolysis products should be clarified. This paper selected the typical components in five distillates of light tar, phenol tar, naphthalene tar, washing tar, and anthracene tar as the main reaction ...
