Ex-situ catalytic pyrolysis of wastewater sewage sludge – A micro-pyrolysis study

Bioresource Technology, 2017
Concerns over increasing amounts of sewage sludge and unsustainability of current disposal methods have led to development of alternative routes for sludge management. The large amount of organics in sewage sludge makes it potential feedstock for energy or fuel production via thermochemical pathways.

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.

Advances in Upgrading Lignin Pyrolysis Vapors by Ex Situ Catalytic Fast Pyrolysis

Energy Technology, 2016
AbstractLignin, a highly branched, substituted, mononuclear aromatic polymer, is one of the principal components of lignocellulosic biomass. Its valorization is considered an important part of the modern biorefinery scheme. However, as a result of the natural complexity and high stability of lignin, its depolymerization and the following conversion are

In-situ catalytic pyrolysis of waste tires over clays for high quality pyrolysis products

International Journal of Hydrogen Energy, 2021
Abstract This paper aims to evaluate the effect of low-cost clays (kaolin with different particle size and montmorillonite (MTT) modified with ZnCl2 and HCl) as catalysts on the pyrolysis products from waste tire. The results show that clays can improve the quality and yield of pyrolysis products.

Clean pyrolysis oil from a continuous two-stage pyrolysis of scrap tires using in-situ and ex-situ desulfurization

Energy, 2017
Abstract Scrap tire pyrolysis was conducted to produce low sulfur oil (below 0.45 wt%), which is strongly demanded for reduction of SOx emissions. In the experiments, a continuous two-stage pyrolyzer consisting of an auger reactor and fluidized bed reactor and various additives (CaO, Fe, FeO, calcined olivine) and fluidizing media (product gas and N2)

Analysis of proteinaceous binders by in-situ pyrolysis and silylation

Chromatographia, 2003
Pyrolysis coupled with gas chromatography and mass spectrometry (Py-GC-MS) is a useful technique for rapid characterization of the organic materials used in art. In the characterization of proteinaceous binders fragments from pyrolysis are of low intensity. Milk, casein, and glue, for example, are sometimes difficult to detect. In the work discussed in

In-situ pyrolysis kinetic analysis and fixed-bed pyrolysis behavior of ex-service wind turbine blades

Waste Management, 2023
After the peak of rapid wind power development, a large amount of wind turbine blades reach/exceed their service life due to aging or damage. These ex-service wind turbine blades (EWTB) will increase the issue of its high-efficient utilization in the future decades.

Analysis of in situ combustion of oil with pyrolysis and vaporization

Combustion and Flame, 2011
Abstract We study one-dimensional flows, when air is injected into a porous medium filled with inert gas, medium or high viscosity oil and water, giving rise to a combustion wave in a process known as high-temperature oxidation (HTO). In the oil we distinguish three pseudo-components: asphaltenes, medium and light oil.

In-situ kerogen extraction via combustion and pyrolysis

Journal of Petroleum Science and Engineering, 2017
Abstract The extraction of organic kerogen from the vast oil shale reserves in Green River, Utah is limited owing to the environmental and technical challenges. This study compares the efficiency of combustion and pyrolysis to extract the kerogen from shale, in terms of organic thermal decomposition temperature, heating rates, and activation energy ...

In-situ and ex-situ catalytic upgrading of vapors from microwave-assisted pyrolysis of lignin

Bioresource Technology, 2018
In-situ and ex-situ catalytic upgrading with HZSM-5 of vapors from microwave-assisted pyrolysis of lignin were studied. The in-situ process produced higher bio-oil and less char than ex-situ process. The gas yield was similar for both processes. The ex-situ process had higher selectivity to aromatics and produced more syngas and less CO2 than the in ...
