    Abstract: Methods for modifying a ZSM-5 zeolite by contacting the zeolite with an alkaline solution prior to combining with a binder material to produce a modified ZSM-5 catalyst extrudate that has substantially longer catalyst life, relative to an untreated ZSM-5 catalyst, for converting light olefins to products that may be used as a liquid transportation fuel blend stock. The alkaline solution is optionally sodium hydroxide. The binder is optionally alumina, bentonite or silica.

    Abstract: A process and system for the conversion of a feedstock comprising C3-C5 light alkanes to a C5+ hydrocarbon product, for example, a BTX-rich hydrocarbon product, by performing the alkane activation (first-stage) and the oligomerization/aromatization (second- stage) in separate stages, which allows each conversion process to occur at optimal reaction conditions thus increasing the overall hydrocarbon product yield. The alkane activation or first- stage is operated at a higher temperature than the second-stage since light alkanes are much less reactive than light olefins. Since aromatization of olefins is more efficient at higher pressure, the second-stage is maintained at a higher pressure than the first-stage. Further, fixed-bed catalysts are used in each of the first-stage and the second-stage.

    Abstract: A method of producing an infiltrated solid oxide fuel cell (SOFC) layer. The method begins by infiltrating a solution containing a solute into a SOFC layer to produce a primary SOFC layer. The primary SOFC layer is then dried in a heated environment, wherein the heated environment ranges in temperature from about 25 °C to about 100 °C to produce a dry primary SOFC layer. The dry primary SOFC layer is then cooled at a rate less than about 5 °C/min to room temperature to produce a cooled primary SOFC layer. The cooled primary SOFC layer is then heated to a temperature greater than 500 °C then quenching to a temperature from about 10°C to about 30 °C to produce an infiltrated SOFC layer.

    Abstract: The present embodiment describes a pipeline interchange, wherein the pipeline interchange has a refined petroleum product flowing through an upstream pipeline. The pipeline interchange can also have an automated slipstream analyzer connected to the upstream pipeline comprising an inlet, a return and an analyzer. In this embodiment, the automated slipstream analyzer is used to collect a sample, analyze the sample, generate data from the sample and return the sample of the refined petroleum product flowing through the upstream pipeline. The pipeline interchange can also have an automatic splitter, downstream of the automated slipstream analyzer, capable of receiving and interpreting the data from the automated slipstream analyzer and directing the refined petroleum product into at least three different downstream pipelines, wherein at least one of the downstream pipelines is an intermix pipeline.

    Abstract: A method of remediating groundwater by injection a first aqueous solution and then a second aqueous solution into a well situated within the area of the groundwater to be remediated. The first aqueous solution comprises an iron ligand while the second aqueous solution comprises an oxidizing agent. It is envisioned that the ppm ratio of the iron ligand to oxidizing agent ranges from about 0.0005 to about 0.1.
