The advantage as biology derv by more and more person place hep, and technical development, the means that uses preparation biology diesel oil is increasing. What be familiar with relatively among them is technology of derv of biology of synthesis of completely acerbity catalysis, this kind of new technology that forms in process of research, development, having distinctive quality, because this is right,its interest also is higher and higher.
Completely acerbity catalysis synthesizes biology derv technology to wait to crude oil of all sorts of deserted grease, vegetable can applicable, and still do not need to undertake to grease usually any pretreatment, undertake ester is changed directly, the de-acidification, come unglued, dehydrate, biology diesel oil that can receive needing except the working procedure such as broken bits. Also be to say, wanting raw material only is grease, whats can no matter among them composition is,receive biology diesel oil, it is among them moisture and machine for certain of course miscellaneous had jumped over lesser. Still having is the technology can shorten greatly sedimentation time, at the same time cost also is reduced accordingly. In whole process, the equipment that involves also has a lot of, include ester to exchange reactor, methanol to reclaim equipment, adsorptive canister is waited a moment; If want to get the car uses oil of essence of life, still need those who add still of filtrate pump, vacuum to wait for device. But this kind of technology still has the place that remains to improve, that is ester exchange time dosage of longer, activator is bigger also, the specific power consumption that uses up accordingly will be some more.
