<p>PURPOSE:To enhance heat resistance and durability of the titled catalytic body by depositing 20-200g/l-carrier activated alumina and 0.1-2g/l-carrier Pt on a monolithic carrier and depositing Pt at the specified position of the surface to be deposited. CONSTITUTION:A catalytic body for burning kerosine-base fuel is formed by coating and depositing 20-200g/l-carrier activated alumina and 0.1-2g/l-carrier Pt on a monolithic carrier and also depositing >=40% of total Pt amount to be deposited in a range within 5mum from the surfacemost layer of the coated layer and depositing >=60% of total Pt amount to be deposited in a range within 10mum from the surfacemost layer. As the raw material of Pt, dinitrodiaminoplatinic acid is preferably used. As the monolithic catalyst, cordierite, mullite and alpha-alumina, etc., are used and the size of the carrier is preferably small to enhance combustion efficiency and is regulated to about 200-600cell/cm<2>.</p> |
