  • Patent number: 9067792
    Abstract: The present invention relates to a direct method to convert fine and ultra fine silicon powder from polysilicon manufacturing sources such as fluid bed and free space reactors into densified granular forms. This conversion process is effected by the use of lasers of selective wavelengths from solid state diode or optically-pumped YAG sources to locally heat, melt and densify a controlled quantity of silicon powder, and comprises the steps of distributing dry silicon powder on an inert substrate, subjecting the silicon charge to a focused laser beam to realize melted and densified granular forms, and discharging the product. When adapted to high purity silicon powder, the end use for the densified silicon granular forms is primarily as feedstock for silicon-based semiconductor and photovoltaic manufacturing industries. The process, suitably modified, is adaptable to form other silicon body shapes and components.

  • Patent number: 8968694
    Abstract: A method for preparing high purity ammonia is provided, which comprises the following three steps of: (1) obtaining the required feed gases (i.e., hydrogen-nitrogen gas mixture) by catalytic cracking ammonia; (2) purifying the hydrogen-nitrogen gas mixture; and (3) synthesizing high purity ammonia by using the hydrogen- nitrogen gas mixture with high purity. In the provided method, the obtained ammonia with undesired purity is fed back to an ammonia catalytic cracking unit. The whole production system is a closed system without any discharging of ammonia and thus is environment friendly. Each step of the method can reduce cost.

The alumina has novel physical properties that, in combination with the catalytic components, provide for the hydroprocessing catalyst. The hydroprocessing catalyst is particularly effective in the conversion of the heavy hydrocarbon feedstock. The alumina is characterized as having a high pore volume and a high surface area with a large proportion of the pore volume being present in the pores within a narrow pore diameter distribution about a narrowly defined range of median pore diameters.

  • Patent number: 8951492
    Abstract: Disclosed are methods and apparatus for providing an ammonia feed for a low-temperature process. The process includes two defined stages, gasification and hydrolysis. In a first stage thermal reactor, an aqueous urea solution is fed to a gasification chamber and heated gases are controlled in response to demand from a low temperature process requiring ammonia. The heated gases and aqueous urea are introduced into the gasification chamber upstream to fully gasify the solution of aqueous urea to a first stage gas stream comprising ammonia and isocyanic acid. The first stage gas stream is withdrawn and maintained hot enough to prevent solids formation. All amounts of urea feed, water and heated gases fed into the first stage thermal reactor are monitored and adjusted as necessary to achieve efficient hydrolysis in the second stage hydrolysis reactor. The second stage gas stream is withdrawn from the second stage reactor responsive to demand from a low temperature process requiring ammonia.
