Using new type catalyst and new process, the continuous operation of reaction regeneration is realized.
The naphtha or condensate is restructured under medium pressure conditions, To produce high octane gasoline (RON up to 95) LPG, According to the process requirements, MTBE can be produced at the same time benzene light diesel (fuel oil) toluene xylene dry gas ether after carbon four. At the same time, the catalyst inside the device rebirth, rebirth without stopping, improve the relative yield, increase the service life of the catalyst, ensure the reaction depth and desulfurization effect.
