Description
Technical field
The present invention relates to a kind of device and method reducing biodiesel metal ion content, belong to new energy and environment skill
Art field.
Background technology
With the continuous variation of energy pattern, world's diesel oil demand will rapidly increase, and the supply of diesel oil is seriously not
Foot, this all provides wide development space for Biodiesel.However due to during production of biodiesel technique and
Different material oil, all can cause biodiesel to contain many different ions, include mainly：Potassium, receive, calcium, magnesium, fluorine, chlorine, bromine,
The insoluble soa and mill that the burning of nitric acid, sulfuric acid, phosphoric acid, formic acid, acetic acid, propionic acid etc., wherein alkali and alkaline-earth metal ions can be formed
The combustion product of damage property solid impurity deposits within the engine generates mechanical wear to metal parts, and halogen and acidic materials can make
Engine chamber component generates acid etching abrasion, influences engine life.Therefore, reduce biodiesel in ion concentration for
The preparation of biodiesel ensures biodiesel fuel quality and safeguards that there is the steady normal operation of engine highly important reality to anticipate
Justice.
Studies have shown that since most of production of biodiesel process is anti-as esterification using sodium hydroxide or potassium hydroxide
The catalyst answered removes certain adsorbents used in impurity or using the calcium generated during hard water removal (or flushing) impurity
And magnesium, it can all cause biodiesel to contain calcium, potassium, magnesium, sodium plasma, combustion product can be such that burning chamber of diesel engine component generates
Corrosive wear.Ash content in biodiesel be mainly remaining catalyst (base catalyst) and metallic element in its feedstock oil and
