This technology uses highly ive and active catalysts to produce second-generation biodiesel via oil hydrogenation. Under conditions of 240 ℃–260 ℃ and 4.0 MPa-8.0 MPa, suspended liquid-phase or fixed-bed reaction modes are ed, resulting an over 95% conversion rate of bio-oils, biodiesel ivity over 90%. The products include long-chain (C12–C22) hydrocarbons, alcohols, and esters similar to fatty acid glycerides, and byproducts can be directly utilized. The technology reduces pollution, simplifies separation, lowers energy consumption and costs, and promotes industrial development toward continuous, pollutionfree, and low-cost production. It is currently undergoing pilot testing.
