Examples
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%.
