Patent number: 9498768Abstract: The present invention is related to the synthesis of a nano-hybrid catalyst made of carbon nanotubes and metal ferrite materials for the removal of NOx compounds, which are emitted from stationary sources, through an ammonia selective catalytic reduction process. Weight ratios of carbon nanotube (x) to metal ferrite (y) is preferably about (x/y) 0.1 to 10. The present invention is also directed to the synthesis of a nano-hybrid catalyst to improve the efficiency of the conventional NOx reduction process at lower reaction temperatures. By use of the preferred nano-hybrid catalyst, it is possible to locate a selective catalytic reduction (SCR) unit capable of operating at lower temperatures, e.g., below 260° C., and from about 50° C. to about 250° C., after the desulfurizer and the particle removal equipment. With the exhaust gas cleaner, the lifetime of the catalyst can be increased. This nano-hybrid catalyst provides higher NOx removal efficiencies at low temperatures, typically from about 50° C.Type: GrantFiled: September 18, 2014Date of Patent: November 22, 2016Assignees: Research Institute of Petroleum Industry, Tarbiat Modaress UniversityInventors: Mahnaz Pourkhalil, Alimorad Rashidi, Abdolsammad Zarringhalam Moghaddam, Mahdi Mohajeri, Ali Mehri
