The process technology can selectively remove the trace dienes and alkynes contained in light hydrocarbon fractions produced by petroleum refining, petrochemical and coal to olefin plants, thereby meeting the requirements for deep processing and utilization of downstream units. 

Technical features:

1. KaiRui technology can ensure high conversion of dienes and maintains high selectivity.

2. KaiRui technology can minimize the occurrence of isomerization side reactions of butene-1 to B-2.

3. KaiRui technology can reduce the loss of monoolefins, ensuring the yield of monoolefins more than 98%.
