Abstract: The yield and quality of products secured from cracking units is increased by the process of subjecting the product stream secured from such cracking unit to a selective aromatics removal process and recycling the recovered aromatics lean (saturates rich) stream to the cracking unit whereby such saturates rich stream is subjected to increased conversion to higher value desired products.

Abstract: In a process for producing phenol, cyclohexylbenzene is oxidized to produce cyclohexylbenzene hydroperoxide and then the resultant cyclohexylbenzene hydroperoxide is cleaved to produce an effluent stream comprising phenol and cyclohexanone. At least a portion of the effluent stream is then fed to at least one dehydrogenation reaction zone, where the effluent stream portion is contacted with a dehydrogenation catalyst under conditions effective to convert at least part of the cyclohexanone in the effluent portion into phenol and hydrogen.

Abstract: There is provided a catalyst composition having improved hydrothermal stability for the catalytic cracking of a hydrocarbon feedstock to selectively produce propylene. The catalyst composition comprises a first crystalline molecular sieve selected from the group consisting of IM-5, MWW, ITH, FER, MFS, AEL, and AFO and an effective amount of a stabilization metal (copper, zirconium, or mixtures thereof) exchanged into the molecular sieve. The catalyst finds application in the cracking of naphtha and heavy hydrocarbon feedstocks. When used in the catalytic cracking of heavier hydrocarbon feedstocks, the catalyst composition preferably comprises a second molecular sieve having a pore size that is greater than the pore size of the first molecular sieve. The process is carried out by contacting a feedstock containing hydrocarbons having at least 4 carbon atoms is contacted, under catalytic cracking conditions, with the catalyst composition.
