In situ catalytic fast pyrolysis of paddy husk pyrolysis vapors over MCM-22 and ITQ-2 zeolites

Journal of Analytical and Applied Pyrolysis, 2015
Abstract Non-catalytic and catalytic fast pyrolysis of paddy husk was performed with a medium pore framework zeolite (MCM-22) and its delaminated counterpart with a higher external surface area (ITQ-2) using a lab scale fixed-bed reactor. This work investigates the influence of the catalyst physical structure on the yields of gas, liquid and solid ...

In-situ and ex-situ catalytic pyrolysis/co-pyrolysis of empty fruit bunches using mesostructured aluminosilicate catalysts

Chemical Engineering Journal, 2019
Abstract Mesostructured aluminosilicates of Al-MSU-F (commercial), Al-SBA-15 (home-made), and mesoMFI (a mesoporous aluminosilicate with MFI structure, home-made), with a silica-to-alumina ratio of 40, were used as catalyst for the in-situ catalytic pyrolysis (CP) of empty fruit bunches (EFB) at 600 °C.

Flash pyrolysis and in situ methylation of humic acids from soil

Organic Geochemistry, 1994
Conventional flash pyrolysis-gas chromatography-mass spectrometry has tradiditionally been used for the characterization of complex geological substances such as humic materials, but the technique appears to provide a biased representation of the structural components of very polar materials such as humic substances, probably because the polar ...

In-situ nitrogen fixation during sludge pyrolysis integrated with biomass gasification process

Journal of Environmental Management
Gasification is a promising strategy for sludge valorization; however, the significant emission of nitrogen-containing compounds presents both environmental and operational challenges. To mitigate this, a novel sludge pyrolysis and biomass gasification (SPBG) method has been developed to enable in-situ stabilization of nitrogen compounds.

Pyrolysis of subbituminous coal in relation to in-situ coal gasification

Fuel, 1978
Abstract Pyrolysis of Roland Seam (Wyodak) subbituminous coal has been investigated from 383 to 1273 K in an inert gas at 0.1 MPa (1 bar). The gas, liquid (condensibles at 0 °C) and solid products were analysed and characterized. Evolution of the major noncondensible gas products was measured quantitatively.
