Latest Patents

Liu's latest patents include a catalyst for catalytic pyrolysis processes aimed at producing light olefins. This catalyst comprises 10-70 wt % of clay, 5-85 wt % of inorganic oxides, and 1-50 wt % zeolite. The zeolite is a mixture of 0-25 wt % of Y type zeolite and 75-100 wt % of high silica zeolite containing phosphorus and aluminum or magnesium or calcium. This catalyst exhibits excellent activity stability and high yields of light olefins, particularly for C2. It operates at lower reaction temperatures compared to traditional steam thermal cracking while achieving comparable yields.

Another notable patent involves the production of gaseous olefins through the catalytic conversion of hydrocarbons. This process utilizes various fractions of petroleum, including residual oils and crude oils, to produce gaseous olefins such as propylene and butylene. The process is conducted in fluidized or moving bed reactors with solid, acidic catalysts in the presence of steam at temperatures ranging from 500°C to 650°C. The total yield of this innovative process is approximately 40 percent by weight of the feedstock.
