Embodiment 1
[0026] Add 100 kilograms of waste engine oil from the feed port. When feeding the oil, first open the gate valve, then open the stop valve, and use the fuel pump to smoothly add the waste engine oil into the reactor. 100 grams of catalyst (catalyst made of 5% Fe 2 O 3 , 30% active Al 2 O 3 , 5% MgO, 30% CaO, 10% SiO 2 , 15% NaOH, 5% KOH, 1% Al 2 (SO 4 ) 3 , 0.1% mixed rare earth composition). Add the catalyst into the reactor through the catalyst inlet. After all the waste engine oil and catalyst are added, close the valve. The reactor is heated to bring the waste engine oil to a temperature of 300°C, and the waste engine oil is subjected to catalytic cracking reaction for 5 hours to obtain distillate gas with a temperature of 180°C. The diesel fraction gas passes through the distillation tower to the fraction control sensor device to control the diesel fraction. The light diesel fraction gas enters the condenser through the pipeline for condensation, and the condensed liquid l...

[0029] Add 100 kilograms of waste engine oil from the feed port. When feeding the oil, first open the gate valve, then open the stop valve, and use the fuel pump to smoothly add the waste engine oil into the reactor. 100 grams of catalyst (catalyst made of 10% Fe 2 O 3 , 20% active Al 2 O 3 , 10% MgO, 20% CaO, 10% SiO 2 , 10% NaOH, 10% KOH, 2% Al 2 (SO 4 ) 3 , 0.2% mixed rare earth composition). Add the catalyst into the reactor through the catalyst inlet. After all the waste engine oil and catalyst are added, close the valve. The reaction kettle is heated to bring the waste engine oil to a temperature of 400°C, and the waste engine oil is catalytically cracked for 5 hours to obtain distillate gas with a temperature of 260°C. The diesel fraction gas passes through the distillation tower to the fraction control sensor device to control the diesel fraction. The light diesel fraction gas enters the condenser through the pipeline for condensation, and the condensed liquid light die...
Embodiment 3
[0032] Add 100 kilograms of waste engine oil from the feed port. When feeding the oil, first open the gate valve, then open the stop valve, and use the fuel pump to smoothly add the waste engine oil into the reactor. 100 grams of catalyst (catalyst made of 8% Fe 2 O 3 , 10% active Al 2 O 3 , 20% MgO, 10% CaO, 20% SiO 2 , 20% NaOH, 5% KOH, 5% Al 2 (SO 4 ) 3 , 0.3% mixed rare earth composition). Add the catalyst into the reactor through the catalyst inlet. After all the waste engine oil and catalyst are added, close the valve. The reactor is heated to make the waste engine oil reach a temperature of 500°C, and the waste engine oil is catalytically cracked for 5 hours to obtain a distillate gas with a temperature of 350°C. The diesel fraction gas passes through the distillation tower to the fraction control sensor device to control the diesel fraction. The light diesel fraction gas enters the condenser through the pipeline for condensation, and the condensed liquid light diesel en...
