【Q&A Question 017】January 17, 2018: What is chemical adsorption? It refers to the adsorption process in which a chemical reaction occurs between the adsorbent and the adsorbate, resulting in the formation of compounds on the surface of the adsorbent. Its adsorption process generally proceeds very slowly, and the desorption process is extremely difficult. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) Due to the limitations on the number of posts in the “One Question per Day” section, “One Image per Day” has been moved to the registered devices section; you can access it through the directory I posted.

Chemical adsorption is a type of adsorption in which there is a transfer, exchange, or sharing of electrons between the adsorbate molecules and the atoms (or molecules) on the solid surface, resulting in the formation of adsorption chemical bonds

What is chemical adsorption? Answer: It refers to the adsorption process in which a chemical reaction occurs between the adsorbent and the adsorbate, resulting in the formation of compounds on the surface of the adsorbent. Its adsorption process generally proceeds very slowly, and the desorption process is extremely difficult.
Chemical adsorption is a type of adsorption in which there is a transfer, exchange, or sharing of electrons between the adsorbate molecules and the atoms (or molecules) on the solid surface, resulting in the formation of adsorption chemical bonds. Due to the uneven force field on the solid surface, the atoms on that surface often possess residual bonding capacity. When gas molecules collide with the solid surface, electron exchange, transfer, or sharing occurs between them and the surface atoms, resulting in an adsorption process that forms adsorption chemical bonds
Chemical adsorption: ① It is caused by the chemical bonding forces between the adsorbent and the adsorbate; it is a single-layer adsorption, and adsorption requires a certain amount of activation energy. ②Adsorption exhibits strong selectivity. ③ The adsorption rate is slow, and it takes a long time to reach adsorption equilibrium. ③ Raising the temperature can increase the adsorption rate.
In adsorption, electron transfer, exchange, and sharing occur between the adsorbate molecules and the atoms (or molecules) on the solid surface, resulting in the formation of adsorption chemical bonds.
