Abstract:

A catalyst precursor composition and methods for making such catalyst precursor are disclosed. The catalyst precursor comprises at least a Promoter metal selected from Group VIII, Group IIB, Group IIA, Group IVA and combinations thereof, at least one Group VIB metal, at least one organic, oxygen-containing ligand, and a cellulose-containing material. Catalysts prepared from the sulfidation of such catalyst precursors are used in the hydroprocessing of hydrocarbon feeds. In one embodiment, the sulfidation is carried out by contacting the catalyst precursor with hydrogen and a sulfur containing compound, wherein the contacting is carried out ex-situ. Catalysts prepared from such catalyst precursors have a fouling rate of less than 8 F. (4. 4 C. ) per 1000 hour.

Abstract:

A solar panel mounting system includes a plurality of solar panel support structures which can be formed from solid concrete in adjacent rows with mounting surfaces that are tilted towards the equator. The solar panels can have an adhesive backing which can be used to secure the solar panels directly to the mounting surfaces. The support structures can be made of concrete and formed with a slip form machine. This construction can reduce the time and materials required for the solar panel installation. The solar panel mounting system can also occupy significantly less ground space than conventional solar panel installations.
