Latest Patents

Xiangcheng Li holds 1 patent for his invention titled "Method for preparing p-xylene by biomass conversion." This method involves a two-step process. The first step includes contacting a biomass starting material with a hydrogenation catalyst in a multiphase system, which consists of an organic solvent, an inorganic salt, and water, in the presence of hydrogen. The resulting product is then separated to obtain an organic phase containing 2,5-hexanedione. The second step involves reacting this organic phase with ethylene using a molecular sieve catalyst to produce paraxylene. The molecular sieve catalyst can be selected from aluminophosphate molecular sieves and SCM-14 molecular sieves.
