    摘要: A microfiltration membrane is provided that includes a patterned side and an un- patterned side and a dense layer located at the patterned side of the membrane. The membrane is useful for the treatment of water and wastewater. The membrane filters 15% more water than an un-patterned membrane. According to various embodiments, the membrane is formed of a polymer casting solution. The patterned side includes projecting features having a size of 1-500μιη, which according to some embodiments include finger-like asymmetric structures. A method of preparing the microfiltration membrane is also provided that includes providing a patterned non-solvent mold, applying a casting solution to the mold, and forming a dense layer at an interface of the non-solvent mold and the casting solution. According to embodiments, the non-solvent mold is a hydrogel mold and the casting solution is a polymer casting solution.

    摘要: A process in which a catalytic cracking unit is operated to crack a hydrocarbon feedstock in a manner to enhance light olefin yields. The accompanying benzene-containing naphtha product stream is further processed through a benzene selective membrane to provide a low content benzene stream Refiners frequently operate their cracking units to optimize light olefin yields, e g, propylene, in response to needs in the petrochemical industry, and it has been discovered that units operated in this manner frequently produce naphtha containing increased amounts of benzene. The method of this invention therefore allows one to operate the unit when it is desired to optimize light olefin yields, yet at the same time produce a naphtha yield having a low benzene content. The invention is particularly useful when the cracking unit utilizes pentasil zeolites at increased concentrations to enhance light olefins yield.
