Title: Lijun Yan: Innovator in Hydrogenation Technology
Introduction
Lijun Yan is a prominent inventor based in Beijing, China. She has made significant contributions to the field of hydrogenation technology, particularly through her innovative patent that addresses the efficiency of recycled hydrogen in high-pressure reactors.
Latest Patents
Lijun Yan holds a patent titled "Apparatus and method for increasing the concentration of recycled hydrogen in a high pressure hydrogenation reactor." This invention discloses an apparatus and method that enhance the concentration of recycled hydrogen in the hydrogenation unit. The design includes a hydration separation unit positioned between the high-pressure separator and the hydrocracking reactor. A portion of the recycled hydrogen interacts with a water-in-oil microemulsion to form hydrates, from which light hydrocarbon components are extracted. The gas flow entering the hydration separation unit constitutes 20% to 100% of the total gas flow from the high-pressure separator. The water-in-oil microemulsion, with a volume ratio of oil to water ranging from 1:1 to 5:1, can increase hydrogen partial pressure in the reactor, thereby improving hydrogenation performance. Lijun Yan has been granted 1 patent for this innovative work.
