Spent FCC catalyst: Potential anti-corrosive and anti-biofouling material
Palak A. Trivedi,Parimal A. Parikh,Preeti R. Parmar 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.4
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 8C and 6 h 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.
Investigation on corrosion control of mild steel buried in soil by spent FCC catalyst coating
Palak A. Trivedi,Nikunj M. Solanki,Naresh Butani,Parimal A. Parikh 한국공업화학회 2014 Journal of Industrial and Engineering Chemistry Vol.20 No.4
Effects of aerobic and anaerobic bacteria on corrosion behaviour of mild steel coated with modified spent FCC catalyst have been examined in soil extract solutions (SES) and that buried in soil. Coating of modified spent FCC catalyst was found to inhibit the growth of bacterial isolates from the soil which is represented as zone of inhibition. Efficacy of spent FCC catalyst was studied for the coated coupons immersed in SES. Cracks and interstices were found on uncoated coupons due to corrosion whereas coated surface remained unaffected. This is confirmed by the SEM analysis. It was also seen that coated coupon was undamaged under buried-in-soil conditions for 30 days.
