Kinetic study of catalytic gasification of wood char impregnated with different alkali salts

, 2017
Different concentrations (0.1 and 1 M K+/Na+) of salt solutions (K2CO3, Na2CO3, NaOH and NaCl) were used to impregnate alkali in sawdust. After devolatilization, char samples were gasified at different temperatures (750–900 °C) under CO2 in a macro ...

The Physical and Chemical Properties of Fine Carbon Particles-Pinewood Resin Blends and Their Possible Utilization

Journal of Chemistry, 2015
The application of biomass gasification technology is very important in the sense that it helps to relieve the dwindling supply of natural gas from fossil fuels, and the desired product of its gasification process is syngas.

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO

The Canadian Journal of Chemical Engineering, Volume 104, Issue 12, Page 6423-6439, December 2026.
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2, air, or less commonly N2O, CO2, or CO) through a micro‐reactor ...

Comparative Investigation of the CO2 Gasification Characteristics of Biomass In-situ Char and Ex-situ Char

, 2015
The CO2 gasification characteristics of in-situ char and ex-situ char of biomass were comparatively investigated by using rice straw and pine as samples. Effects of char structure and metal catalyst on difference of the char gasification reactivity were

Kinetic analysis and model evaluation for steam co-gasification of coal-biomass blended chars using macro-TGA

Fuel Processing Technology
A macro-thermobalance (macro-TGA) was applied to investigate the steam co-gasification characteristics of the chars produced from Huainan coal (HN), two types of biomasses, sawdust (SD) and wheat straw (WS), and coal-biomass blends at 900–1200 °C under ...

Investigation of Systematic Discrepancies Between MCC and TGA Measurements Affecting the Determination of Heat of Combustion

Fire and Materials, Volume 50, Issue 7, Page 771-787, November 2026.
ABSTRACT The determination of step‐resolved effective heats of combustion is essential for detailed pyrolysis modelling in fire growth and flame spread predictions, especially in multi‐step processes where the heat of combustion can differ between reaction steps.

Thermovolumetric investigations of steam gasification of coals and their chars

E3S Web of Conferences, 2017
The process of steam gasification of three coals of various rank and three chars obtained from these coals by the ex-situ method at 900 °C was compared. In the coal gasification process, the pyrolysis stage plays a very important part, which is connected
