Gas solid reaction example
WebGas-solid reactions are one of the mainstays of extractive metallurgy--the process is called roasting. Roasting consists of thermal gas–solid reactions, which can include oxidation,... WebAdsorption is the process by which a gas (or solution) phase molecule (the adsorbate) binds to solid (or liquid) surface atoms (the adsorbent). The reverse of adsorption is desorption, the adsorbate splitting from adsorbent. In a reaction facilitated by heterogeneous catalysis, the catalyst is the adsorbent and the reactants are the adsorbate.
