本発明は船舶燃料油中の接触分解触媒の除去方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION (Related Industrial Field) The present invention relates to a method for removing catalytic cracking catalysts from marine fuel oil.
（従来技術）
燃料油中に混入する触媒粒子は粒径１〜１０μｍ濃度１
１００ｐｐ程度のものが多く、従来遠心油清浄機、精密
濾過器などを船上の燃料供給ラインに設置し清浄化して

、精密濾過器のフィルタは再生が困難で使い捨てとされ
ていた。(Prior art) Catalyst particles mixed into fuel oil have a particle size of 1 to 10 μm and a concentration of 1
Most of the oil is around 100 pp, and conventionally centrifugal oil purifiers, precision filters, etc. have been installed in the fuel supply lines onboard ships to clean it. In order to prevent wear caused by catalyst particles, it is necessary to remove most particles of 1 to 5 μm or more, but since the particle size is small, both centrifugal oil purifiers and precision filters have small processing capacities and cannot be used with large-sized ones. I had no choice but to accept it. In addition, the filters of precision filters were difficult to regenerate and were considered disposable.

なっていた。(Problem to be solved) As the production of middle distillates such as jet fuel, light oil, and A heavy oil has been increased due to the increasing weight of heavy oil and the decrease in the amount of crude oil processed, C
As the production volume of heavy oil has decreased, the proportion of catalytic cracking oil being mixed with C heavy oil for marine diesel engine fuel has increased. Catalytic cracking of petroleum uses a zeolite catalyst containing aluminum, silica, and a small amount of iron, which becomes fine particles and mixes with the cracked oil, causing abnormal wear of piston rings, cylinders, and fuel pumps in marine diesel engines. In the worst case scenario, this caused the ship to become unable to navigate, creating a problem.

A high gradient magnetic separator can easily magnetize and separate even weakly magnetic substances due to the action of the high magnetic gradient generated within the separator.

１５０ｍ＋程度で十分である。The magnetic separation performance of fuel oil at a temperature of 120°C varies depending on the strength of the applied magnetic field, but a particle removal rate of about 80% can be obtained at a magnetic field strength of 5 Gauss and a linear velocity of 10 m/if/h. . At this time, it is sufficient for the filter filling height of the magnetic separator to be about 150 m+.
