Latest Patents

One of Liu's latest patents is for a nitrogen-phosphorus-modified granular carbon-supported bimetallic catalyst. This invention provides a catalyst that comprises a nitrogen-phosphorus-modified carbon carrier and metal particles supported on the carbon carrier. The metal particles include first metal elementary substance particles, second metal elementary substance particles, and bimetallic alloy phase particles. Notably, the percentage of the bimetallic alloy phase particles in the metal particles is at least 80%, with 90% of the alloy phase particles having a size ranging from 1 nm to 20 nm. This catalyst boasts advantages such as a high proportion of alloy phase particles, a uniform particle size distribution, a high metal utilization rate, low costs, high stability, and exceptional catalytic activity.

Another significant patent involves a method for preparing 2,3-dichloro-5-trifluoromethylpyridine with high selectivity. This method operates at a temperature of 100 to 150 degrees Celsius and a pressure of 0.5 to 5.0 MPa, utilizing at least one catalyst selected from supported metal chloride, supported zeolite molecular sieve, and supported heteropolyacid. The process allows for the reaction of 2-chloro-5-trifluoromethylpyridine with chlorine gas to yield the desired product. The advantages of this method include high selectivity for the desired product, efficient utilization of chlorine gas, moderate process conditions, simple operation, and reduced waste.
