Abstract: Generally, it is disclosed a catalyst for use in a hydrotreating hydrocarbon feedstocks and the method of making such catalyst. It is generically provided that the catalyst comprises at least one Group VIB metal component, at least one Group VIII metal component, about (1) to (about (30) wt % C, and preferably about (1) to about (20) wt % C, and more preferably about (5) to about 15 wt % C of one or more sulfur containing organic additive and a titanium-containing carrier component, wherein the amount of the titanium component is in the range of about (3) to (about (60) wt %, expressed as an oxide (Ti02) and based on the total weight of the catalyst. The titanium-containing carrier is formed by co-extruding or precipitating a titanium source with a Al203 precursor to form a porous support material comprising Al203 or by impregnating a titanium source onto a porous support material comprising Al203.

Abstract: Disclosed is a catalyst for use in hydrotreating hydrocarbon feedstocks and methods of making the same catalyst. Specifically, a catalyst is disclosed comprises at least one Group VIB metal component, at least one Group VIII metal component, an organic additive resulting in a C-content of the final catalysts of about 1 to about 30 wt % C, and preferably about 1 to about 20 wt % C, and more preferably about 5 to about 15 wt % C and a titanium-containing carrier component, wherein the amount of the titanium component is in the range of about 3 to about 60 wt %, expressed as an oxide (TiO2) and based on the total weight of the catalyst. The titanium-containing carrier is formed by co-extruding or precipitating a titanium source with a AI2O3 precursor to form a porous support material primarily comprising AI2O3 or by impregnating a titanium source onto a porous support material primarily comprising AI2O3. Special preference is given to alumina and alumina containing up to and no more than 1 wt % of silica, preferably no more than 0.5 wt % based on the total weight of the support (dry base).

Abstract: The present invention relates to a process for adding an organic compound to a porous solid wherein, in an open or closed chamber, a first batch of porous solid rich in an organic compound is brought together with a second batch of porous solid low in said organic compound. The step of bringing the porous solids together is carried out under temperature, pressure and time conditions such that a fraction of said organic compound is transferred gaseously from the first batch of porous solid to the second batch of porous solid.

Abstract: A method of making a multifunctional catalyst for upgrading pyrolysis oil includes contacting a hierarchical mesoporous zeolite support with a solution including at least a first metal catalyst precursor and a second metal catalyst precursor, each or both of which may include a heteropolyacid. The hierarchical mesoporous zeolite support may have an average pore size of from 2 nm to 40 nm. Contacting the hierarchical mesoporous zeolite support with the solution deposits or adsorbs the first metal catalyst precursor and the second catalyst precursor onto outer surfaces and pore surfaces of the hierarchical mesoporous zeolite support to produce a multifunctional catalyst precursor. The method further includes removing excess solution and calcining the multifunctional catalyst precursor to produce the multifunctional catalyst comprising at least a first metal catalyst and a second metal catalyst deposited on the outer surfaces and pore surfaces of the hierarchical mesoporous zeolite support.
