Abstract
To combat corrosion and biofouling in chemical and marine industries with green and cheap material many efforts are put. Efficacy of spent FCC catalyst coating was studied for these purposes. Its corrosion resistance against corrosive media was examined up to 80°C and 6h by two methods. They indicated high corrosion inhibition efficiency. Antibacterial and antibiofouling activity of zeolite was studied for bacteria isolated from seawater. Zeolite coating was subjected to cooling water to observe antifouling behaviour and the performance was found to improve upon some modifications. The metal deposited on zeolite did not leach away in stagnant and flowing waters.
