can any one tell me about the difference of Stabilize Naphtha and Unstabilize Naphtha? Advantages of Continuous Catalytic Reforming Process? which kind of Naphtha is introduced in BTX Unit to get high recovery of Toluene?

In most cases, the word "stabilized" (as it pertains to naphtha or other gasoline blending stocks in a petroleum refinery) means that the lighter boiling compounds, such as butane or propane or lighter, have been almost completely removed from the naphtha or gasoline blend stock. Thus, the bottoms stream from a naphtha debutanizer distillation tower would be a stabilized naphtha. On the other hand, the feed stream to a naphtha debutanizer would be an unstabilized naphtha.

The primary advantage of a continuous catalytic reformer is that the spent catalyst is continuously regenerated and re-used within the unit ... as compared to non-regenerative catalytic reformers where the catalyst must be removed and replaced when the catalyst is spent (i.e., the catalyst activity has declined to the point that it is no longer useful). I am sure that a search using www.google.com would yield many articles on the advantages and disadvantages of continous catalytic reformers.

A BTX unit within a petroleum refinery would usually be fed with a naphtha which has been processed through a catalytic reformer operating at a high-severity so as to produce a reformed naphtha that is rich in aromatics such as benzene, toluene and xylene (i.e., BTX).
