    Abstract: An apparatus and method for vaporizing and transporting an alkali metal salt is shown. The apparatus has a first conduit capable of transporting an alkali metal salt solution and a second conduit in fluid communication with the first conduit, the second conduit capable of transporting steam so that the alkali metal salt is dissipated into the steam forming a solution that can be transported, such as to a remote reaction zone. The solution can be transported via a third conduit that is capable of being heated by a heat source. The method can be used to add a promoter to a dehydrogenation catalyst during a dehydrogenation reaction.

    Abstract: Alkylation systems and methods of minimizing alkylation catalyst regeneration are described herein. The alkylation systems generally include a preliminary alkylation system adapted to receive an input stream including an alkyl aromatic hydrocarbon and contact the input stream with a preliminary alkylation catalyst disposed therein to form a first output stream. The preliminary alkylation catalyst generally includes a zeolite catalyst having a SiO2/Al2O3 ratio of less than about 25. The alkylation systems further include a first alkylation system adapted to receive the first output stream and contact the first output stream with a first alkylation catalyst disposed therein and an alkylating agent to form a second output stream.

    Abstract: A method of preparing a polystyrene blend that includes combining a first polystyrene composition having a first melt flow index with a second polystyrene composition having a second melt flow index and forming a polystyrene blend, the second melt flow index being at least 2 dg/min higher that the first melt flow index. The polystyrene blend has an observed tensile strength value greater than 3% above the expected tensile strength value. The second polystyrene composition can include a recycled polystyrene material, which can include expanded polystyrene. An alternate method of preparing the polystyrene blend includes combining a polystyrene composition with a styrene monomer to form a reaction mixture, polymerizing the reaction mixture and obtaining a polystyrene blend, where the polystyrene containing composition has a melt flow index at least 2 dg/min higher than the melt flow index of the styrene monomer after it has been polymerized.
