Providing a method for generating and releasing 1-MCP gas from a complex carrier through the use of a 1-MCP generator that enables the application of at least one physical, releasing force to a carrier complex and/or mixture comprising water and the carrier complex, or the interaction of steam with a carrier complex and/or mixture comprising water and the carrier complex, over a determined period of time.
PADDLE CONFIGURATION FOR A PARTICLE COATING REACTOR
A reactor for coating particles includes a stationary vacuum chamber to hold a bed of particles to be coated, a chemical delivery system, and a paddle assembly. The paddle assembly includes a rotatable drive shaft and a first plurality of paddles and a second plurality of paddles that extend radially from the drive shaft. The spacing, cross-sections, and oblique angles of the paddles are such that orbiting of the paddles causes the first plurality of paddles and the second plurality of paddles to displace substantially equal volumes in opposite directions in the lower portion of the stationary vacuum chamber.
Method for enhancing leaching of metals in zinc hypoxide powder by mechanochemistry coupling with sonochemistry
Disclosed is a method for enhancing leaching of metals in zinc hypoxide powder by mechanochemistry coupling with sonochemistry, comprising the following: mechanical activation: a raw material containing zinc hypoxide powder is mechanically activated so that an activated material is obtained; and ultrasonic treatment: the activated material is mixed with an acidic leaching solution to obtain a mixture, the mixture is subjected to ultrasonic treatment, and a liquid phase is obtained as the leachate. Mechanochemical activation and ultrasonic chemistry synergistically enhance the leaching efficiency and leaching rate of multiple metals through the destruction and cavitation of the zinc oxide powder structure. This process can indirectly reduce the concentration of the used acidic leaching solution and shorten the leaching duration. In practical production, the specific application of the process can reduce the anticorrosion cost and running cost of reaction equipment, indirectly leading to excellent production benefit.

PRODUCTION OF LITHIUM CHEMICALS AND METALLIC LITHIUM
A process and system are disclosed for producing lithium oxide from lithium nitrate. In the process and system, the lithium nitrate is thermally decomposed in a manner such that a fraction of the lithium nitrate forms lithium oxide, and such that a remaining fraction of the lithium nitrate does not decompose to lithium oxide. The thermal decomposition may be terminated after a determined time period to ensure that there is a remaining fraction of lithium nitrate and to thereby produce a lithium oxide in lithium nitrate product. The lithium oxide in lithium nitrate product may have one or more transition-metal oxides, hydroxides, carbonates or nitrates added thereto to form a battery electrode. The lithium oxide in lithium nitrate product may alternatively be subjected to carbothermal reduction to produce lithium metal.
