Inert ceramic balls are the most widely used support medium in the world due to their excellent consistency and reliability. It has excellent stability, high mechanical strength and thermal shock resistance, can withstand high temperature, high pressure and corrosion of acids, alkalis, salts and various organic solvents, and can be widely used in petroleum, chemical, fertilizer, natural gas and environmental protection, etc. industry. As a support and cover material for the catalyst in the reactor, it can buffer the impact of the liquid and gas entering the reactor on the catalyst, protect the catalyst, and improve the distribution of liquid and gas in the reactor, which makes it an ideal choice for all types of catalyst carriers.
