High value organic-enhanced inorganic fertilizers

Номер: AU2012236575A1
Принадлежит:

The invention is directed to the manufacture of fertilizer having commercial levels of nitrogen supplemented with organic substances, e.g., 16-0.5-2-17-3-14 (N-P- K-S-Fe-Organic by dry weight). The process causes treatment of organic matter with concentrated acid that heats a fertilizer mix causing the hydrolysis of various organic polymers that may be present. A biosolids mix is subsequently injected sequentially with a nitrogen base under controlled conditions. The resultant sterilized and liquefied organic matter is then disbursed over recycled material for the production of granules in a granulator before final drying to greater than 98 percent solids. Because the process allows for the controlled addition of acids and ammonia, desired levels of components can be achieved. For example, fertilizers with high nitrogen content can contain variable amounts of phosphate or iron. In addition, the process is both scalable, odor controlled and safe thereby allowing for the location of biosolid ...

Process and Apparatus for Steam-Methane Reforming

Номер: US20120058028A1

Methane reacts with steam generating carbon monoxide and hydrogen in a first catalytic reactor; the resulting gas mixture undergoes Fischer-Tropsch synthesis in a second catalytic reactor. In the steam/methane reforming, the gas mixture passes through a narrow channel having mean and exit temperatures both in the range of 750° C. to 900° C., residence time less than 0.5 second, and the channel containing a catalyst, so that only reactions having comparatively rapid kinetics will occur. Heat is provided by combustion of methane in adjacent channels. The ratio of steam to methane may be about 1.5. Almost all methane will undergo the reforming reaction, almost entirely forming carbon monoxide. After Fischer-Tropsch synthesis, the remaining hydrogen may be fed back to the combustion channels. The steam for the reforming step may be generated from water generated by the chemical reactions, by condensing products from Fischer-Tropsch synthesis and by condensing water vapor generated in combustion.

Deep desulfurization of hydrocarbon feeds containing undesired organosulfur compounds to produce a hydrocarbon product having low levels of sulfur, i.e., 15 ppmw or less of sulfur, is achieved by first subjecting the entire feed to an extraction zone to separate an aromatic-rich fraction containing a substantial amount of the aromatic refractory and sterically hindered sulfur-containing compounds and an aromatic-lean fraction containing a substantial amount of the labile sulfur-containing compounds. The aromatic-rich fraction is contacted with isomerization catalyst, and the isomerized aromatic-rich fraction and the aromatic-lean fraction are combined and contacted with a hydrotreating catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level.

A wire standoff suitable for use in a tubular reactor, such as a reformer, is described. The wire standoff includes a portion or segment positioned between an outer reactor tube and one or more reactor components located within the tube. The reactor components and the outer tube are prevented from coming into directed contact with one another by the positioning of the wire standoff. The wire standoff can be secured to a reactor component at one of its ends or to a washer located between stacked reactor components. Prevention of the reactor components from contact with the outer tube promotes fluid flow through the reactor and can enhance heat transfer and reactor efficiency for carrying out catalytic reactions.

System And Method For Producing Neopentyl Glycol

Номер: US20160031775A1
Принадлежит:

The present invention describes a process for production of neopentyl glycol (NPG) from formaldehyde (FD) and isobutyraldehyde (IBD). FD and IBD first react to form hydroxypivaldehyde (HPD) in an aldol condensation step, then HPD is hydrogenated to form NPG in a hydrogenation step. The aldol condensation step is performed using a solid catalyst such as an ion exchange resin catalyst, which can be easily separated from the reaction product. The feed to the aldol condensation step is made homogeneous by adjusting the ratio of IBD, FD, and water in the feed or by adding a solvent that is miscible with both IBD and water.
