Described herein is a cost effective means for selenium recovery and refining relying on an impregnated substrate. The substrate is impregnated with selenium and provides a system and method for the environmentally safe discharge of previous selenium-contaminated solutions and an environmentally safe discharge of industrial waste water.

Selenium removal methods and systems

An integrated process for the conversion of carbohydrate containing materials to gasoline boiling range hydrocarbons is disclosed. A carbohydrate containing material may be converted to a hydrogenated carbohydrate containing material with a bi-functional catalyst. The hydrogenated carbohydrate containing material may be reacted in the presence of another catalyst to form a reaction product containing non-aromatic and aromatic gasoline boiling range hydrocarbons.

Integrated process for converting carbohydrates to hydrocarbons

Methods and apparatus relate to removal of mercury from crude oil. Such removal relies on transferring mercury from a liquid hydrocarbon stream to a natural gas stream upon contacting the liquid hydrocarbon stream with the natural gas stream. Processing of the natural gas stream after used to strip the mercury from the liquid hydrocarbon stream removes the mercury from the natural gas stream.

Mercury removal from crude oil

Methods and apparatus relate to treating fluid to at least reduce selenium content within the fluid, which may be an aqueous liquid and form a feed stream. The treating removes selenium that may be present in compounds, such as selenocyanate, from the feed stream based on adsorption from contact of the fluid with a sorbent. Flowing a gaseous hydrogen sulfide and sulfur dioxide containing stream over a support, such as activated carbon, may provide the sorbent impregnated with sulfur and utilized in the treating of the fluid.

Selenium removal process

A composition, containing vanadium and a support, wherein at least a portion of the vanadium has crystallite sizes of less than about 100 &#x212b; as determined by an analytical method such as X-Ray Diffraction, is disclosed. A method of preparing such composition is also disclosed. The composition is employed in a process to remove a heavy metal from a gaseous feed stream which can optionally include a separate mercury adsorption stage.

Process for the removal of heavy metals from gases

A process is disclosed for removing mercury from a liquid hydrocarbon stream by contacting the mercury-containing liquid hydrocarbon stream with ferrous halide at moderate temperatures and without preheating the liquid hydrocarbon stream, or subjecting the liquid hydrocarbon stream to a heat treating step, immediately prior to contact with the ferrous halide particles.

Mercury removal from hydrocarbons

A process for removing mercury from an aqueous stream using a supported selenium and sulfur material is disclosed.

Mercury removal process

Process for the removal of heavy metals from gases, and compositions therefor and therewith

A process is disclosed for removing heavy metals from a hydrocarbon gas stream by contacting the hydrocarbon gas stream, which contains a heavy metal and less than 10 ppm oxidizing compounds, with a composition containing a molecular sieve and sulfur resulting in a treated stream containing less heavy metal than the hydrocarbon gas stream; wherein the molecular sieve contains alumina, silica, and iron, and optionally copper and zinc. Optionally, the hydrocarbon gas stream can also contain a sulfur compound.

Removal of heavy metals from hydrocarbon gases

A sorbent composition comprising a vanadium compound and a ZrOsupport material is disclosed. Methods of making and using the composition to remove heavy metals or heavy metal containing compounds from a fluid stream are also provided. Such methods are particularly useful in the removal of mercury and mercury compounds from flue gas streams produced from the combustion of hydrocarbon-containing materials such as coal and petroleum fuels.

Mercury removal sorbent

A composition comprising a vanadium oxide compound and an alkali metal promoter loaded onto a porous support material is disclosed. Methods of making and using the composition to remove heavy metals or heavy metal containing compounds from a fluid stream are also provided. Such methods are particularly useful in the removal of mercury and mercury compounds from flue gas streams produced from the combustion of hydrocarbon-containing materials such as coal and petroleum fuels.

A process for the simultaneous removal of HS and SOfrom tail gases is disclosed. A tail gas stream is contacted with a sorbent in a sorption zone to produce a product gas stream and a sulfur laden sorbent, wherein the sorbent comprises Zn and a promoter metal. A process for the recovery of sulfur is also disclosed. A tail gas stream is contacted with a sorbent in a sorption zone to produce solid sulfur, wherein the sorbent comprises Zn and a promoter metal, wherein the promoter metal is manganese.

Sulfur recovery process

A system employing a regenerable zinc-oxide based sorbent to remove one or more contaminants from an incoming gas stream. The contaminant-depleted gas stream can then be used for any subsequent application, while at least a portion of the contaminant-laden sorbent can be regenerated via a step-wise regeneration process. In one embodiment, sorbent regenerated via the step-wise regeneration process can comprise less sorbent-damaging compounds than traditional sorbents exposed to conventional regeneration processes.

Contaminant removal from a gas stream

A process for the simultaneous removal of HS and SOfrom tail gases is disclosed. A tail gas stream is contacted with a sorbent in a sorption zone to produce a product gas stream and a sulfur laden sorbent, wherein the sorbent comprises Zn and a promoter metal.

Processes for the conversion of carbohydrates to gasoline boiling range hydrocarbons, and processes for increasing the solubility of carbohydrates used in such processes are disclosed. The solubility of carbohydrates may be increased by contacting the carbohydrate with an ion-exchange resin. The dissolved product may be hydrogenated and reacted in the present of a catalyst to form a reaction product containing non-aromatic and aromatic gasoline boiling range hydrocarbons.
