Effect of Methylcyclopentadienyl Manganese Tricarbonyl Injection on the Catalytic Reforming Process Improvement of the Gasoline Ron in an Oil Refining Installation

Pierre Jean Marie Richard DABLE


Abstract— Gasoline is produced by mixing reformat gotten with light essence. The catalytic reforming process that occurs under severe conditions causes damage to the catalysts. To preserve the cycle duration of the catalysts, a Refining Company is planning to reduce the RON of the reformat and to add the Methylcyclopentadienyl Manganese Tricarbonyl in abbreviation MMT, to the mix. This additive should improve the gasoline. The present study shows out that for this purpose, the reforming process would operate under less severe condition and would produce a reformat with 92.5 RON instead of 95. The working temperature will be 5°C less and the cycle duration would gain three (3) months with a reduction of the consuming of fuel by the furnace. Under this new working temperature, even so the produced gas phase flow would be less; 1.35 ton per hour instead of the formerly 1.72 ton per hour, it should be richer in hydrogen; 96% instead of 92% obtained formerly. This gas could be directly used in the hydrocracking process.
