Embodiment approach 1
[0027] Such as figure 1 As shown, 100 t of raw materials were obtained after the collected waste oil was removed from impurities, and the raw materials were sent into a light-transmitting strengthened glass reactor filled with titanium dioxide photocatalysts. The mass ratio of raw materials to catalysts was 100:1. Under sunlight conditions, the reaction temperature is 25o C, the reaction pressure is 1 atm, waste oil undergoes decomposition reaction to produce 90 t of green diesel oil, and its composition mass percentage is 53% of hydrocarbons ((in C 16 Mainly straight chain alkanes, a small amount of C 5 -C 9 alkanes and C 5 -C 8 olefins)), fatty acids 10%, esters 34% and water 3%, and CO 2 Gas 10 t (CO 2 The mole percentage is greater than 75%, others are a small amount of C 3 The following low-carbon hydrocarbons). The generated green diesel oil is directly used as a flotation agent for the flotation of coking coal blending, and 90,000 tons of clean coking coal can b...
Embodiment approach 2
[0029] Such as figure 1 As shown, 100 t of raw materials are obtained after the collected waste oil is removed from impurities, and the raw materials are sent into a light-transmitting strengthened glass reactor filled with bismuth oxybromide photocatalyst, and the mass ratio of raw materials to catalysts is 100:1 , under sunlight conditions, the reaction temperature is 25 o C, the reaction pressure is 1 atm, waste oil undergoes decomposition reaction to produce 88 t of green diesel oil, and its composition mass percentage is 46.5% of hydrocarbons (in C 16 Mainly straight chain alkanes, a small amount of C 5 -C 9 alkanes and C 5 -C 8 olefins)), fatty acids 12.4%, esters 36.2% and water 4.9%, and CO 2 Gas 12 t (CO 2 The mole percentage is greater than 80%, the others are a small amount of C 3 The following low-carbon hydrocarbons). The generated green diesel oil is directly used as a flotation agent for the flotation of coking coal blending, and 86,000 tons of clean co...
Embodiment approach 3
[0031] Such as figure 1 As shown, 100 t of raw materials are obtained after the collected waste oil is removed from impurities, and the raw materials are sent into a light-transmitting strengthened glass reactor filled with bismuth oxyiodide photocatalyst, and the mass ratio of raw materials to catalysts is 100:1 , under sunlight conditions, the reaction temperature is 25 o C, the reaction pressure is 1 atm, waste oil undergoes decomposition reaction to produce 85 t of green diesel oil, and its composition mass percentage is 44.4% of hydrocarbons (in C 16 Mainly straight chain alkanes, a small amount of C 5 -C 9 alkanes and C 5 -C 8 olefins)), fatty acids 13.9%, esters 36.1% and water 6.6%, and CO 2 Gas 15 t (CO 2 The mole percentage is greater than 83%, the others are a small amount of C 3 The following low-carbon hydrocarbons). The generated green diesel is directly used as a flotation agent for flotation of coking coal blending, and 79,500 tons of clean coking coal...
