The molecular sieve powder has the effective performances of adsorption and selectivity. it is suitable with application of insulating glass desiccant, refrigerant desiccant. Powder are widely used as catalysts in the refining of crude oil into finished petroleum products.Zeolites are also increasingly finding use in the production of petrochemicals, often replacing environmentally unfriendly catalysts. Unlike more hazardous acid catalysts that have been used in the past, zeolites are non-hazardous, regenerable, and non-corrosive.
