Brief introduction SPJ-212-1 contains a unique high-temperature anti-coking and anti-fouling component can form a protective film in the furnace tube, and then can efficiently prevent the unstable components coking in the furnace tube. If the product is added into device in the mid-run period, it can strip the coke layer and dirt layer effectively. The temperature of the furnace tube can be reduced 10 to 40 centigrade in 48hrs after the 100ppm SPJ-212-1 added. Using the product for a long-term can extend the run period of the furnace and system doubled. SPJ-212-1 is a non-silicon product, so there is no cracking silicide evaporating into the coking liquid product, so it will not lead to subsequent processing catalyst poisoning.
