<p>This invention relates to a system for the preparation of a high quality gasoline through the recombination of catalytic hydrocarbon and its process. The characteristics are as follows: the upper part of the fractionator is connected with light petrol hydrogenation unit through the light petrol pipeline. The lower part of the fractionator is connected with the extractor through the heavy petrol pipeline. The upper part of the extractor directly extracts the product through the pipeline and the lower part of the extractor is connected to the light petrol pipeline behind the light petrol hydrogenation unit. Compared with the prior art, this invention has the following advantages: the volume of used catalyst is greatly reduced. In addition, the sulfur reduction and olefin reduction effect are remarkable by using the hydrogenation units with special catalysts and parameters regarding different petrol fractions.</p> |
