A catalyst for converting hydrocarbon, a method of making the same, and a method of using the same are provided. Such a catalyst includes a zeotype microporous material, a binder material, and a metal phosphide, which can be in a range of from 0.01% to 10% by weight of a total weight of the catalyst. For example, such a catalyst can be used to convert light alkene or alkane into aromatic hydrocarbon such as benzene, toluene, xylenes, and a combination thereof. The alkene may be ethylene, propylene, butylene, or a combination thereof. The alkene may be supplied directly or from a stream converted from light alkane such as methane, ethane, propane, butane, or a combination thereof.

A steam-assisted catalytic cracking process for a hydrocarbon feed is provided. The process includes: introducing the hydrocarbon feed, a fluid catalytic cracking (FCC) catalyst, and steam to a FCC reactor with a mass ratio of steam to hydrocarbon feed between 0.05 and 1.0; cracking the hydrocarbon feed in the presence of the FCC catalyst and steam to produce a cracked hydrocarbon feed and spent FCC catalyst, the spent FCC catalyst comprising coke deposits and hydrocarbon deposits; stripping the hydrocarbon deposits from the spent FCC catalyst with steam in a stripper to obtain a hydrocarbon-stripped spent FCC catalyst; regenerating the hydrocarbon-stripped spent FCC catalyst in a regenerator by subjecting the stripped spent FCC catalyst to heat in the presence of oxygen to combust the coke deposits on the stripped spent FCC catalyst and produce a regenerated FCC catalyst; recycling the regenerated FCC catalyst.

The present invention is directed toward an article of footwear with an improved eyelet system independent of the upper. The article of footwear includes an upper and a sole structure, where the sole structure includes a top surface, a bottom surface, a lateral side and a medial side. The article of footwear further includes an eyelet system coupled to the top surface of the sole structure. The eyelet system includes a base structure and a plurality of looped strand portions coupled to the base structure. The base structure is coupled to the top surface of the sole structure such that the plurality of looped strand portions extend outwardly from the sole structure, enabling the looped strand portions to receive a fastening element.

Systems and methods are provided for conversion of oxygenate feeds to lubricant and/or distillate boiling range compounds with desirable properties by first selectively converting oxygenates to light olefins and then converting the light olefins to distillate and lubricant boiling range compounds with beneficial properties. The distillate boiling range products can have an unexpectedly high cetane, while the lubricant boiling range products can have an unexpectedly high viscosity index. The ability to form the distillate boiling range products and lubricant boiling range products is facilitated by using a Ni-enhanced oligomerization catalyst.
