Abstract

The invention discloses a method for preparing biodiesel by utilizing a plasma method. The method is used for producing the biodiesel under the catalysis of a high-voltage electric field. According to the method, main equipment comprises a safety pump, a chemical reactor, a pulsed power supply and a collecting container; a reaction temperature is within 69 DEG C to 95 DEG C and optimally selected within 75 DEG C to 85 DEG C. The method comprises the following steps: carrying out a discharge product chain reaction for about 15 to 45 minutes by keeping the temperature of a reaction tank to be greater than 69 DEG C; and then stirring and standing so as to obtain the light-colored biodiesel. The method is good in effect, i.e., the produced biodiesel has good quality and excellent startability and has the accelerating ability equal to that of diesel No.0; the produced biodiesel is good in lubricity, so that the abrasion of a machine is reduced; the produced biodiesel is high in flash point, so that the high safety is realized; a crude glycerine taken as a by-product is not generated, so that treatment works during the production tail are reduced; the generation of pollutions in the production process is avoided.

Description

A kind of plasma is prepared biofuel method

Technical field

The present invention relates to plasma technology field, relate in particular to a kind of automatization preparation method of biofuel.

Background technology

At present, China is domestic is all to adopt " two-step approach " to prepare biofuel, it is ripe that the method technology can be said to be, the biofuel quality of producing is yet stable, but the starting material that shortcoming is preparation biofuel must pass through pre-pre-treatment, and acid value, moisture and impurity are had to very strict requirement, and technical process complexity, because the usage quantity of methyl alcohol is large, so the follow-up flow process that must have Methanol Recovery, recovery difficult is large; Aspect catalyzer, catalyzer will be used the vitriol oil and the highly basic that corrodibility is strong, and energy consumption is high, cost is large, and for this situation, a kind of method that plasma is prepared biofuel is now invented by my company, the advantage of this method is that (1) technical process is simple, do not use catalyzer, do not need to use alcohol recovery process, in room temperature situation, operate, transformation efficiency reaches 98%, production cost is low, and the whole production process three wastes are few, without discharging of waste liquid; (2) the biofuel quality of producing is good, through evidence, in the biofuel that uses separately this method to prepare in use, startability is good, and accelerating ability and No. 0 diesel oil equate, and its lubricity is good, the wearing and tearing of machine are reduced, and flash-point is high, and safety performance is high.(3) there is no the generation of byproduct raw glycerine, reduce the work for the treatment of of producing the later stage.

Summary of the invention

By high-voltage, molecular structure is split again, obtain biofuel from new arrangement

Using combination of reclaimed grease+methyl alcohol+high-voltage---" biofuel+hydrogen

Major equipment: 1 safety pump 2 chemical reactor 3 pulse power 4 collection containers

Method:

Power supply: the galvanic current of minimum 1800 volts, use larger voltage, carbochain is just shorter, pulsed voltage is 800 8000V/inch (anode and cathode distance), in 2 seconds, reacted, in order to control battery performance well, the resistance between negative electrode and anode is an important factor.The anode surface of the small bubbles of the shroud gas of controlling during the high voltage operation that approaches (0.01mm is to 25mm).Be trapped in anode carrier backwash gas and hold enough bubble fractile maintenances, resistance R 3=25,000 ohm applies voltage with the maximum of permission under stable condition., the value of resistance is directly determined the peak voltage applying.

Temperature: approximately 69 DEG C to 95 DEG C of temperature of reaction, preferably between 75 to 85 DEG C.Keep retort temperature to be greater than 69 DEG C, stirring after the discharging product chain reaction of approximately 15 to 45 minutes completes, rotating speed 300 r/min, with the current-series connection of 250mA.

Structure: consider from the angle of safety, the wall thickness of isolation pipeline section must be used for safe applying voltage to electrode.The entrance that flows is vertical with the outlet of flowing, and anode and cathode is loaded in pipe.PVC 80 pipes can be processed 3,200 volts of volts DSs of RTO safely, if contacted with tube wall, TGO guarantees enough safety groundss, are placed on the processing conduction of cell plastic components and non-ly should place conductive fluid.Keep good power supply control, safe and reliable

Produce: by recovered oil (abendoned oil lipid) and methyl alcohol, by calculating, (weight fraction of the alcohol in the mixture of oily and alcohol is between 12% to 15% according to a certain percentage,) enter after proportioning is good, fluid enters qualified rear electric field, generates biofuel through the effective catalysis of high-voltage electric field.

After reaction, produce biofuel, productive rate approaches 100%, does not produce the generation of the domestic byproduct raw glycerine by any additive method production biofuel at present, solves recovery, the treating processes of follow-up series of complex.
