Preparation of CaO-rich briquette from powdered semi-cokes by cold-pressing

In this work, CaO-rich briquette coke was prepared by carbonizing the cold pressing briquette composed of powdered char, CaO, and binders. The influences of binder type, binder content in briquette, the CaO/char ratio, and carbonization condition on compressive strength, resistivity, and porosity of...

Summary:In this work, CaO-rich briquette coke was prepared by carbonizing the cold pressing briquette composed of powdered char, CaO, and binders. The influences of binder type, binder content in briquette, the CaO/char ratio, and carbonization condition on compressive strength, resistivity, and porosity of the briquette were investigated. Subsequently, the optimum preparation conditions for producing CaO-rich briquetting coke were determined. The obtained results can promote development and optimization of in-situ production of calcium carbide and acetylene from CaO-rich briquetting coke.
