Description

Technical Field

[0001] The utility model relates to the technical field of methanol gasoline production equipment, in particular to a distillation catalytic modification device. Background Art

[0002] Methanol gasoline refers to a new, environmentally friendly fuel made by blending national standard gasoline, methanol, and additives in a strict process according to a specific volume ratio. Currently, in the manufacturing process of methanol gasoline, the raw material is mostly modified through distillation catalytic modification equipment. During the modification, a solid catalyst is first added to the distillation catalytic modification equipment, forming a fixed bed layer inside the equipment. The raw material then flows through the stationary fixed bed layer through the gaps between the particles, and a catalytic reaction occurs. However, because the solid catalyst is located inside the distillation catalytic modification equipment, it cannot be automatically discharged from the distillation catalytic modification equipment, making it difficult for users to remove the used solid catalyst from the distillation catalytic modification equipment, resulting in inconvenience.
