Abstract

The invention relates to a biological liquid fuel and a preparation method thereof. The adopted technical scheme is that the biological liquid fuel is prepared by the following raw materials in percentage by weight: 59.8 to 85 percent of methanol, 0.01 to 1 percent of porcellanite, 0.5 to 1 percent of carbon tetrachloride, 10 to 30 percent of straw or sawdust pyrolysis oil, 0.1 to 1 percent of ethyl acetate, 0.01 to 0.5 percent of tertiary butanol, 0.1 to 1 percent of peregal, 0.5 to 1.5 percent of hydrogen peroxide, 3 to 6 percent of water and 0.1 to 0.3 percent of alkyl fatty acid sodium. The method for preparing the straw or the sawdust pyrolysis oil comprises the following steps: drying the straw or sawdust; placing the dried straw or sawdust into a fully-enclosed reaction kettle; rapidly cracking the straw or the sawdust under a pressure of 1.0 MPa and at the temperature of below 550 DEG C to obtain an oil phase in a liquid product; and uniformly mixing the raw materials.

Description

Biological liquid fuel and preparation method thereof

Technical field

The invention belongs to the liquid fuel field, relate to a kind of liquid fuel that utilizes the bio-waste preparation and preparation method thereof particularly.

Background technology

Beginning since second industrial revolution, the ore class energy just is widely applied, and becomes the leading role of the energy, along with the mankind are increasing to the demand of the energy, the ore class energy is exploited without restraint, but the ore class energy comprising: coal, oil, Sweet natural gas etc. all are the non-renewable energy.This undying exploitation has not only destroyed ecotope, and these resources are also more and more deficienter.Simultaneously, rural area etc. have a large amount of wastes such as stalk etc. to be dropped again, not only influence environment, and cause the waste of resource.

Summary of the invention

In order to overcome the above problems, the invention provides the biological liquid fuel of preparations such as a kind of waste that utilizes farm crop such as stalk, not only protected natural resources and enviroment, greatly reduce production cost and use cost simultaneously.

Wherein, the preparation method of described stalk or sawdust pyrolysis oil is as follows: after stalk or wood chip oven dry, the totally-enclosed reactor of packing into is 1.0Mpa at pressure, and temperature is under 550 ℃, the oil phase in the quick cracking gained of stalk or the wood chip product liquid.

The preparation method of above-mentioned biological liquid fuel is characterized in that the preparation method is as follows:

1) by above-mentioned proportioning, takes by weighing raw material;

2) earlier tetracol phenixin and stalk or sawdust pyrolysis oil are placed in the container, 60～70 ℃ were evenly stirred 10～20 minutes cooling down; Add the trimethyl carbinol, 10～15 ℃ were evenly stirred 10～20 minutes down, make mixture A;

3) water and Peracetic Acid are mixed, add white bole and ethyl acetate then successively, make mixture B;

4) with mixture A, mixture B, peregal and alkyl fatty acid sodium mix, and stir after 30～60 minutes, make mixture C;

5) in mixture C, add methyl alcohol, mix and stirred 30 minutes.

The biological liquid fuel of the present invention's preparation, technical indicator such as table 1 that it reaches.
