Abstract: Disclosed are a catalytic method and system for producing aromatic hydrocarbons from aliphatic hydrocarbons or light naphtha. In an aspect, the process comprises adding a diluent comprising a heavy aromatic hydrocarbon (for example, C7-C9+) to a reactor feedstock comprising aliphatic hydrocarbons (for example, C6-C8) or light naphtha to form a reactor feed stream, such that the heat capacity of reactor feed stream is higher than the heat capacity of feedstock. The reactor feed stream is heated and contacting with a catalyst under conditions sufficient to aromatize at least a portion of the aliphatic hydrocarbons and form a product stream comprising a primary aromatic hydrocarbon product and a heavy aromatic hydrocarbon product. In an aspect, the diluent can comprise a heavy aromatic hydrocarbon having at least one carbon atom more than the primary aromatic hydrocarbon product.

Abstract: A collapsible box that provides access through both its top and front side. When set up, said box comprises a (i) horizontal upper section and (ii) horizontal lower section, said sections attached to each other via a pair of opposed vertical sidewalls. When said upper section is gripped by hand and lifted upwardly, said upper section will separate from said lower section and the box will open. Each of said sidewalls comprises a set of upper and lower panels, said panels attached to each other via a hinge that extends horizontally across the approximate center of said sidewall. The top of each sidewall is attached to one end of said upper section via a horizontal hinge; the bottom of each sidewall is attached to one end of said lower section via a horizontal hinge. Said lower section comprises the floor of said box. Said upper section comprises the top lid and two panels that rest horizontally underneath said top lid.

Abstract: A collapsible box with a pair of opposed, hinged sidewalls in which a lightweight frame structure holds the sidewall in a vertical orientation during assembly and provides load-bearing strength. The frame structure and sidewalls fold over one another, and lie substantially flat, when said box is collapsed.

Abstract: A packing case molded from plastic materials comprises two side walls including two half-walls rotatably connected to each other by tenon/mortise joint and hinge elements, two end walls rotatably connected to the adjacent side walls by tenon/mortise joint and hinge elements, and two cover plates removeably intersecting with said connected walls, thereby to form a foldable container which can easily pack or unpack without need of any external means, and can be folded into a collapsed form that is easily recovered for further use.
