Ignition experiments with two bituminous coals were carried out in an atmospheric bubbling fluidized bed combustor (FBC) and a thermogravimetric analyzer (TGA). In the FBC tests, the rapid increase in O2, CO2, and ...

A novel pyrometallurgical process for the synthesis of porous forsterite by calcination in chlorine of a mixture containing hydromagnesite and silica gel was developed. The aim of this work was to produce porous forsterite ...

In the last decades a new class of thermoset phenolic resin is emerging as a substitute of the traditional epoxy and phenolic resins in the aircraft industry. This new class is called polybenzoxazines and its associates ...

The goal of this work is to analyze the effect of carbon nanotubes (CNTs) on the pyrolysis of either high density polyethylene (PE) or polypropylene (PP) matrices by using both kinetic thermogravimetric analyses (TGA) ...

Charcoal has a large share in the Brazilian market. The production is carried out by pyrolysis of biomass at different temperatures, between 300 and 500 degrees C. In this study, the corn cob pyrolysis was investigated ...

Biomass and coal have different physicochemical properties and thermal behavior. During the co-combustion of coal-biomass mixtures, their thermal behavior varies according to the percentage of each fuel in the mixture. ...

A thermoset polymer can be used for specific applications by creating a unique chemical composition that is designed for certain characteristic environments. To know the behavior of a thermoset polymer, it is necessary ...

Polymorphism analysis of pharmaceutical raw materials is considered one of the most relevant evaluations that should be done. As we know, different crystal forms from the same molecule have differences in terms of their ...

Thermal decomposition kinetics of solid rocket propellants based on hydroxyl-terminated polybutadiene-HTPB binder was studied by applying the Arrhenius and Flynn-Wall-Ozawa's methods. The thermal decomposition data of the ...
