Development and Characterization of Improved Thermochemical Materials

2021
The IEA Solar Heating and Cooling Programme, Subtask 2T focuses on the development of improved TCM materials, which are based on sorption (micro/mesoporous solids and liquids (hydroxides)), chemical reactions (salt hydrates and metal oxides/hydroxides) and combinations (zeolites / graphite + salt hydrates / metal).

Thermal conductivity measurement of thermochemical storage materials

Applied Thermal Engineering, 2015
Thermal properties related to heat and mass transfer are crucial when designing thermochemical heat storage systems. Therefore, enhancing this phenomenon lies in the thermal conductivity of the used material. The effective thermal conductivity of salt hydrates and host matrices is measured using two different methods by differential scanning ...

Material processing using arc plasmatrons with thermochemical cathodes

8th International Congress on Energy Fluxes and Radiation Effects, 2022
To heat oxygen-containing media in various technological processes, a special class of electric arc plasma generators is used, which use a thermochemical cathode based on hafnium or zirconium. Information about such electrodes is given and their performance in plasmatrons for cutting metals, spraying powder materials, heating gases with a power of 10 ...

Kinetics of thermochemical pretreatment of lignocellulosic materials

Applied Biochemistry and Biotechnology, 1989
The results of an experimental study of the acid hydrolysis of hardwood are presented in the form of values for the three parameters, activation energy, power on the acid concentration, and pre-exponen-tial factor, of the first order kinetic constants for each of the following reaction participants: xylan remaining, glucan remaining, xylose formed, and

Determination of Thermochemical Properties of Aerospace Materials

44th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2008
A new algorithm is developed and assessed to calculate the Arrhenius parameters and the resin (or analogous binder) volume fraction. These parameters were calculated from TGA experiments results. The algorithm is based on iterative Maximum Decomposition method.

Thermochemical Treatment of Porous Materials

1982
The study of chromizing and aluminizing by pack cementation of nickel base alloy felts has resulted in some original observations due to the high porosity of the material. In particular, the exchange mechanisms between the powder and the felt, the localized depletion of the powder and the modification of its activity have been studied.

Appearance of thermochemical emf in some conducting materials

Combustion, Explosion, and Shock Waves, 1982
The appearance of an emf in conductors when they are heated is described by the Seebeck and Thompson effects. If some part of the surface of a conductor is covered by a pyrotechnical material and ignited, then while the pyrotechnical material is burning and after it has burned, an emf arises at the ends of the conductor.

Topic: Materials for Thermochemical Energy Storage

2016
Materials for thermochemical energy storage based on gas-solid reaction have higher energy storage densities than conventional materials for latent and sensible heat storage. These materials furnish the potential to use industrial waste heat as a heat source. Here, research and development of materials for thermochemical energy storage are introduced.
