The present invention relates to a process for producing surface-postcrosslinked water-absorbent polymer particles comprising polymerizing droplets of a monomer solution, wherein water-absorbent polymer particles having an average particle diameter from 420 to 700 μm, an amount of water-absorbent polymer particles having a particle size of less than 300 μm of less than 5% by weight and an amount of water-absorbent polymer particles having a particle size of more than 800 μm of less than 5% by weight are coated with at least one surface-postcrosslinker and thermal surface-postcrosslinked.
Abstract:
A reactor system containing one or more loop reactors for olefin polymerization is provided. The loop reactors include vertical sections, elbow sections, and/or horizontal sections connected into one or more loop reaction zones to polymerize an olefin monomer in the presence of a liquid diluent into a slurry comprising particles of a polyolefin polymer. The reactor system footprint is reduced to increase production efficiency and save cost, while maintaining a high processing capacity. In one embodiment a horizontal length (L H ) of at least one horizontal section is greatly reduced with maintained processing capacity. In another embodiment, at least one elbow section of the reactor system is configured to maintain a Dean number (D n ) of the slurry flowing therein to be higher than 3,000,000.
Abstract:
A reactor and process for the production of bio-diesel. The reactor includes one or more coiled reaction lines. The lines are positioned within a tank containing a heat transfer media such as molten salt, maintained at about 750° F. A pump circulates the media within the tank. An emulsion of alcohol; refined feed stock, including glycerides and/or fatty acids; and preferably water is pumped through the reaction lines at temperatures and pressures sufficient to maintain the alcohol in a super-critical state. The curvature of the coils, pump pulsing, and the flow rate of the emulsion keep the emulsion in a turbulent state while in the reactor, ensuring thorough mixing of the alcohol and feed stock. The alcohol reacts with the glycerides and fatty acids to form bio-diesel. The reaction is fast, efficient with regard to energy input and waste generation, and requires minimal alcohol.
Abstract:
Systems and methods for heating a non-combustion chemical reactor with thermal energy from a geothermal heat source are described. A working fluid is directed from the geothermal heat source to the chemical reactor to transfer heat. The working fluid can be circulated in a closed system so that it does not contact material at the geothermal heat source, or in an open system that allows the working fluid to intermix with material at the geothermal heat source. When intermixing with material at the geothermal heat source, the working fluid can transport donor substances at the geothermal heat source to the chemical reactor.
Abstract:
The present invention relates to an SCC having an enhanced mobility of a removal object by a distance between upper levels being wider than that of lower levels. The present invention provides the SCC, comprising: a housing having a rotary shaft; at least one reaction substance supply portion which is formed inside the housing; spinning cones, at least two of which are installed on the rotary shaft so as to have a specific tilted angle from an upper end to a lower end, for transferring a reaction substance that is supplied by the reaction substance supply potion, and for rotating with the rotary shaft at the center; fixing cones, which are fixedly formed on an inner surface of the housing, and are positioned on the lower end of each of the spinning cones that provide a path for sequentially transferring the reaction substance from the spinning cone at the upper end to the spinning cone at the lower end; a product collection portion for collecting the reaction substance which is transferred through the spinning cones and the fixing cones; and a driving portion for rotating the spinning cones, wherein one pair of consisting of the spinning cone and the fixing cone is considered to comprise a level, at least one distance between the upper levels is wider than that between lower levels. The SCC, according to the present invention, can improve the mobility of the removal object by the SCC having the at least one distance between the upper levels being wider than that between the lower levels.

A reactor vessel including: an upper inlet and a bottom discharge; a generally vertically oriented sidewall between the upper inlet and bottom discharge, wherein the sidewall defines a perimeter of an interior flow passage in the vessel; a first pair of support plates arranged on opposite sides of the sidewall, wherein the first pair of support plates reduces a cross-sectional flow area of the flow passage in a first single direction of convergence, and a second pair of support plates arranged on opposite sides of the side wall, wherein the second pair of support plates reduces a cross-sectional flow are of the flow passage in a second single direction of convergence, wherein the second single direction is angularly offset to the first single direction, and the second pair of support plates is at a different elevation of the vessel than the first pair of support plates.
Abstract:
A method of processing light fraction tar includes pre-heating the light fraction tar before directing it through a reactor. The reactor has a top and a bottom and a surface spanning between said top and said bottom. A film of the light fraction tar flows down the surface under the force of gravity and with heated gas blowing thereon. The portion of the film that reaches the bottom of the reactor has improved properties making it more widely useful for carbon products.
