YJ314 High Strength Activated Alumina

    White ball-shaped particles,regular in particle sizes,smooth at surface,with high mechanical strength and strong adsorption of moisture,not expanding and caracking after adsorbing water,original shape kept.

    Used as a defluorinating agent of drinking water,a defluorinating agent of cyclical alkane in alkyl bezzenes production,a deacidifying-regenerant of transformer oil,and as dryer,purifying agent,catalyst and carrier in chemical fertilizer,petrochemical industries.

YJ316/318 Activated Alumina

    White or slightly red ball-shaped particles,with higher specific surface,porosity volume,production diameter value and lower Na2O content.

    Used as a dryer,adsorbent of hydrogen peroxide production,calalyst carrier of chermical production.

YJ353 Catalyst Carrier for Extracting Residual Oil

    White ball-shaped or slightly red roll-shaped particles with high activity,high strength and good performance of water absorption and purification.

    Suitable for catalyst carrier in bydrogenetion reactions during extracting residual oil,also as drying agent,purifying agent and other catalyst carriers.

YJ332 Catalyst for Recovering Sulphur

    A white ball-shaped particle,insoluble in water and organic solvent,soluble in acidic and alkaline solutions,moisture adsorptive in air,not expanding and cracking after adsorbing water,with the characters of high srength and good thermal stability.

    Used as a catalyst in the claus sulfur recovering unit for treating gases with sulfuric acid containing in petrochemical and other industries,with its high inversion rate,long durability and effective desulfurizing on exhaust gases.
