Embodiment 1

[0040] Embodiment 1, refer to figure 1 . This example takes the inverted U-shaped tube reactor 1 as an example, prepare a mixture of methanol and catalyst at a ratio of dissolving 20 grams of sodium methoxide per liter of methanol, close the valve 23, store the mixture in a vessel 21, and mix it at a temperature of 40 ° C. 1 hour. Adjust the frequency to 4Hz, adjust the amplitude to 3mm, turn on the oscillation device, and adjust the metering pump 24: make CH 3 The flow rate of OH+NaOMe mixture is 0.509l / h, the flow rate of palm oil is 2.591l / h, the reactants (catalyst-containing methanol and palm oil) are extracted from the respective vessels, and heated to 60°C and input into reactor 1 . After the reaction is completed under the above parameters, the product (crude biodiesel+glycerin) first enters the separator 34 for separation, and the separated methanol-containing crude biodiesel enters the water washer 32 to wash away the methanol. The washed biodiesel first passes ...

Embodiment 2

[0042] Embodiment 2, when a large production volume requires multi-level strengthening, it can be used figure 2 or 3 options. All the other are with embodiment 1.

Embodiment 3

[0043] Embodiment 3, the embodiment of the reactor of other forms is as Figure 7-13 , 20-28. All the other are with embodiment 1. When the diameter of reactor 1 is bigger, can adopt hollow piston 5, refer to Figure 7 , 8 , 26-28.

Abstract

The intention relates to a technological method and equipment for preparing biodiesel by palm oil, used for enhancing the production efficiency, the conversion rate and the quality of the biodiesel and regulating and controlling the composition of the biodiesel. The technological method comprises the following steps of: respectively and continuously inputting catalyst-containing methanol and the palm oil through an inlet of a reactor according to a proper proportion, wherein the reactor is provided with an oscillation intensifying device for enhancing the reaction effect, controlling the composition of products and enhancing the reaction rate and the conversion rate; and after the reaction is completed at proper frequency and amplitude, continuously effusing generated products from an outlet of the reactor, and then separating, washing with water, filtering water, absorbing water, and the like. The piston frequency and the amplitude of a regulation and control intensifying device can regulate and control the flow state, the retention time, product components and the conversion rate of materials or achieve the plug flow of the materials; the regulation and control intensifying device has large regulation elasticity and wide application range, regulates the movement velocity, the geometrical shape and dimension and the space position of a regulation piston driving mechanism or the mode of baffle plate replacement and can meet various reaction conditions; in addition, the palm oil has extensive source and low price.

Description

technical field [0001] The invention relates to a process and equipment for preparing biodiesel from palm oil, belonging to the fields of energy, chemistry and chemical industry. Background technique [0002] Mineral oil is gradually being exhausted, and the rising price poses a severe test to the world economy. Countries all over the world are affected by the soaring oil price; the damage to the environment caused by traditional fuels is becoming more and more serious, and it is imminent to find renewable and environmentally friendly energy. Biodiesel (fatty acid methyl ester) is a renewable, efficient, safe and clean energy. It has many advantages that are beyond the reach of petrochemical diesel and are urgently needed by human beings: 1. Renewable and inexhaustible, it will truly realize the eternal energy sustainable use, maintain and promote the coordinated and sustainable development of resources, environment, and social economy. 2. No pollution. Unlike mineral dies...
