Renewable diesel fuel for petrochemical diesel.

Biodiesel is a type of biomass energy, which is similar to petrochemical diesel in physical properties, but has a different chemical composition.

Biodiesel is a mixture of complex organic components with extremely high oxygen content. These mixtures are mainly organic substances with large molecular weights, including almost all kinds of oxygen-containing organic substances, such as: esters, ethers, aldehydes, ketones, phenols, organic acids, alcohols Wait.

Composite biodiesel uses waste animal and vegetable oils, waste engine oils and by-products from oil refineries as raw materials, then adds catalysts, and is synthesized by special equipment and special processes.
