Embodiment 1

[0024] Mix 4.0g soybean stalks (particle size less than 20 mesh) with 0.60g sunflower oil, add 0.12g iron, and add 0.40ml water, stir and mix evenly, compact it into a 10ml miniature airtight reaction kettle, and heat up at 80°C / min The temperature was raised to 400° C. and kept for 20 minutes to end the reaction. After the reaction is cooled, the reaction product is distilled at atmospheric pressure, the fraction at 60-500°C is collected, and the water in the collected liquid is separated to obtain hydrocarbon fuel oil mainly composed of alkanes and aromatic hydrocarbons. The calorific value of fuel oil is 42.71MJ / kg, and the oxygen content is less than 6%.

[0025] figure 1 It is the GC-MS total ion chromatogram of the obtained hydrocarbon fuel oil with alkanes and aromatics as main components. Analysis of the mass spectrogram shows that the main components of hydrocarbon fuel are:

[0026] (1) Hydrocarbons mainly include: decane, octane, nonane, decane, undecane, dodecan...

Embodiment 2

[0030] Mix 4.0g of peanut shells (particle size less than 20 mesh) with 1.00g of sunflower oil, add 0.15g of aluminum oxide, and add 0.40ml of water, stir and mix evenly, then compact it into a 10ml airtight reaction kettle, at 10℃ / Raise the temperature to 450°C at a heating rate of min, keep it for 25 minutes, and end the reaction. After the reaction is cooled, the reaction product is distilled at atmospheric pressure, the fraction at 60-500°C is collected, and the water in the collected liquid is separated to obtain hydrocarbon fuel oil mainly composed of alkanes and aromatics. The calorific value of fuel oil is 43.21MJ / kg, and the oxygen content is less than 5.5%.

Embodiment 3

[0032] Mix 4.0g of lawn grass clippings (particle size less than 20 mesh) with 1.5g of peanut oil, add 0.25g of manganese, and add 0.30ml of water, stir and mix evenly, compact it into a 10ml closed reaction kettle, and heat up at a rate of 40°C / min. The temperature was raised to 350° C. and kept for 10 minutes to end the reaction. After the reaction is cooled down, the reaction product is distilled at atmospheric pressure, the fraction at 60-500°C is collected, and the water in the collected liquid is separated to obtain hydrocarbon fuel oil mainly composed of alkanes and olefins. The calorific value of fuel oil is 40.87MJ / kg, and the oxygen content is less than 7%.

Abstract

The invention relates to the technical field of comprehensive utilization of biomass oil and animal and vegetable oil, in particular to a method for preparing hydrocarbon fuel oil by mixing the biomass oil and the animal and vegetable oil. Simple process flow is adopted in the method; and a mixture of the biomass oil and the animal and vegetable oil is converted into the hydrocarbon fuel oil withthe properties and the components (taking fractions such as gasoline, diesel oil, kerosene and the like as the main components) similar to those of petroleum at a certain temperature by adopting a small amount of water as a medium and adopting transition metals, a molecular sieve and the like as catalysts. Different kinds of biomass oil and animal and vegetable oil are mixed according to different proportions, so that the alkane content can be obviously increased and the properties of the fuel oil can be improved. The calorific value of the obtained fuel oil is 36 to 45 MJ / kg and the oxygen content is less than 7 percent.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of biomass and animal and vegetable oil, in particular to a method for preparing hydrocarbon fuel oil by mixing biomass and animal and vegetable oil. Background technique [0002] The depletion of traditional energy sources and the pollution of the environment require the development of new renewable energy sources. As renewable energy sources, animal and vegetable oils and biomass have received more and more attention and research. As an environmentally friendly renewable resource, biomass does not release additional carbon dioxide, has low sulfur content, a wide range of raw materials, and is cheap; animal and vegetable oils are also environmentally friendly renewable resources, and the source of raw materials is also extensive. However, the current utilization of animal and vegetable oils is mainly biodiesel, and biodiesel is mainly carboxylic acid ester compounds obtained thr...
