A catalyst having at least one Group VIB metal component, at least one Group VIII metal component, a phosphorus component, and a boron-containing carrier component. The amount of the phosphorus component is at least 1 wt %, expressed as an oxide (PO) and based on the total weight of the catalyst, and the amount of boron content is in the range of about 1 to about 13 wt %, expressed as an oxide (BO) and based on the total weight of the catalyst. In one embodiment of the invention, the boron-containing carrier component is a product of a co-extrusion of at least a carrier and a boron source. A method for producing the catalyst and its use for hydrotreating a hydrocarbon feed are also described.

Hydrotreating catalyst containing phosphorus and boron

Producing high purity lithium solution from a lithium source containing dissolved Na, Ca, and Mg, by: passing the source into and out of a bed of sorbent composed of hydrated alumina intercalated with LiX, preferably LiCl, to extract lithium from the lithium source into the sorbent; washing the bed of sorbent with dilute aqueous LiCl to remove lithium from the sorbent to obtain a lithium eluent of increased Liconcentration; subjecting this eluent to nanofiltration to produce a lithium permeate from which Ca2+, Mg2+, and other nanofilterable components are concurrently removed, yielding a permeate solution with 25% or less, and a retentate solution with 75% or more Caand Mg, as compared to the eluent from washing; and subjecting the permeate solution to a particular forward osmosis yielding a solution having 13,000-25,000 ppm dissolved lithium. Specified optional steps and new features can be used to increase lithium concentrations and purity.

The invention pertains to a carrier composition comprising (a) at least 30 wt % of a synthetic cracking component, based on the total weight of the carrier composition, which comprises oxidic compounds of one or more trivalent metallic elements, tetravalent metallic elements, and divalent metallic elements, said cracking component comprising elemental clay platelets with an average diameter of 1 &mgr;m or less and an average degree of stacking of 20 platelets per stack or less, and/or comprising a cogel with a saponite content C of less than 60%, in which the total of sodium and potassium amounts to less than 1 wt %, based on the total weight of the cogel, and (b) 1-25 wt % of a zeolite Y, based on the total weight of the carrier composition, with a unit cell size below 24.35 &angst;. The invention further pertains to a catalyst comprising said carrier composition and at least a hydrogenation metal, and a process for converting heavy feedstock into middle distillates using said catalyst.
