Embodiment 1
[0031] Embodiment 1: Gasoline production process with synthesis gas as figure 1 , the methanol synthesis reactor 201 adopts such as image 3 Horizontal graded water-cooling tower with a diameter of 4.0 meters and a built-in copper-based methanol catalyst of 150M 3 , the methanol dehydration reactor 202 adopts such as Figure 4 Horizontal water cooling tower, with a diameter of 3.8 meters and an upper catalyst layer of 81 pieces of gamma-alumina 30M 3 , the middle and lower catalyst layers 82 and 83 are equipped with ZSM-5 molecular sieve catalyst 100M 3 , the synthesis gas compressed to 6 MPa merges with the recycle gas, and is heated to 230°C and enters the methanol synthesis reactor 201, and the methanol synthesis reaction is carried out on the methanol catalyst layer at a temperature of about 250°C. The heat of reaction is absorbed by the water in the horizontal water pipe in the synthesis tower to produce steam, the pressure of steam drum 71 is lower than the steam pres...
Embodiment 2
[0034] Embodiment 2: use syngas one-step method to make gasoline combined with IGCC production process see figure 2 , the methanol synthesis reactor 201 adopts such as image 3 Horizontal graded water-cooling tower with a diameter of 3.5 meters and a built-in copper-based methanol catalyst of 110M 3 , the methanol dehydration reactor 202 adopts such as image 3 Horizontal water-cooling tower with a diameter of 3.3 meters and a ZSM-5 molecular sieve catalyst of 90M 3 , the synthesis gas compressed to 5.5MPa is heated to 220°C and enters the methanol synthesis reactor 201, and the methanol synthesis reaction is carried out on the methanol catalyst layer at a temperature of about 250°C. The heat of reaction is absorbed by the water in the horizontal water pipe in the synthesis tower to by-produce steam, and the CH in the gas of methanol synthesis reactor 201 is released. 3 The OH content is 46%, and it exchanges heat with the methanol dehydration reactor 202 to 300°C and ente...
