Abstract:
Embodiments of methods and apparatuses for forming a low-metal biomass-derived pyrolysis oil are provided. The method comprises the steps of filtering a biomass-derived pyrolysis oil with a high flux rate filter arrangement having a flux rate of about 10 L/m2/hr or greater to form a low-solids biomass-derived pyrolysis oil. The low-solids biomass-derived pyrolysis oil is filtered with a fine filter arrangement having a pore diameter of about 50 μm or less to form an ultralow-solids biomass-derived pyrolysis oil. The ultralow-solids biomass-derived pyrolysis oil is contacted with an ion-exchange resin to remove metal ions and form the low-metal biomass-derived pyrolysis oil.

Abstract:
In alternative embodiments, the invention provides processes and methods for the recovery or the removal of the so-called “Minor Elements” consisting of iron, aluminum and magnesium (expressed as oxides), from wet-process phosphoric acid using a continuous ion exchange approach. In alternative embodiments, use of processes and methods of the invention allows for the reduction of these Minor Elements with minimal phosphate losses and dilution in order to produce a phosphoric acid that is suitable for the production of fertilizer products such as world-class diammonium phosphate (DAP), merchant-grade phosphoric acid, superphosphoric acid, and other phosphoric acid products. Further, use of the invention would allow the use of lower grade phosphate rock or ore, which would greatly expand the potential phosphate rock reserve base for phosphate mining activities, and allow for better overall utilization of resources from a given developed mine site.
Abstract:
A hydrogen purification device including a container, a first opening structure and a second opening structure is provided. The container has at least a filter material inside. The first opening structure is disposed in the container, wherein hydrogen-rich gas mixture flows into the container via the first opening structure so that purified hydrogen gas is generated by conducting a reaction between the hydrogen-rich gas mixture and the filter material. Besides, a second opening structure is disposed in the container, wherein the purified hydrogen gas flows away from the container via the second opening structure. A fuel processor having the hydrogen purification device is also provided.

Abstract:
Mass transfer sorption processes involve passage of a processed aqueous solution through a layer of granulated sorbent pre-filled with an organic liquid immiscible with either water or an aqueous solution under treatment. The apparatus for mass transfer of sorption processes is a vertical tank with inlet and outlet fittings loaded with a layer of sorbent disposed between the upper and the lower distribution and drainage systems. The industrial plant for separation of the components of aqueous solutions of inorganic substances includes the said apparatus and the apparatus for the separation of organic liquids from aqueous solutions. The latter has a casing with three chambers, the middle one of which is separated from the first outer one by a grid and from the other by a hydrophobic drainage layer. The emulsion to be separated is introduced into the middle chamber, and the separation results are derived from the outer chambers.
Abstract:
Provided is an apparatus for recovering amines from amine-containing waste water generated in power stations, etc., and regenerating a cation exchange resin. The apparatus includes: a cation exchange resin layer capturing amines from amine-containing waste water and eluting the amines therefrom; a degassing tower degassing the eluted amines; a vacuum pump connected to the degassing tower; and a condensation and cooling tower condensing the degassed amines at a temperature of −33° C. or lower, wherein the amines captured in the cation exchange resin layer are eluted by injecting a strong acidic solution, while the resin is regenerated, and the amines eluted by the strong acidic solution is subjected to vacuum degassing and then recovered. Provided also is a method for recovering amines and regenerating a cation exchange resin using the apparatus. The apparatus and method for recovering amines and regenerating a cation exchange resin improve the quality of effluent water from power stations, etc., and increase the cost-efficiency through the recycle of amines.
Abstract:
Disclosed is a process for the production of d-tagatose from lactose after acid hydrolysis to provide a hydrolysate having 1 equiv of d-glucose and 1 equiv of d-galactose for each unit of lactose converted. More particularly, the invention relates to a process for the isomerization of d-galactose to d-tagatose and the use of a simplified separation scheme based on simulated moving bed (SMB) separation. The isomerization of d-galactose to d-tagatose is carried out in the presence of calcium oxide or calcium hydroxide. The process is useful for providing a simplified processing route to providing pure d-tagatose and glucose as two products from lactose hydrolysate. In an alternate embodiment, a process is disclosed for the production of d-tagatose from fermented lactose hydrolysate to provide a crystallized d-tagatose product. D-tagatose is useful as a food additive, as a sweetener, as a texturizer, as a stabilizer, or as a humectant.
