Abstract

A method for regenerating activated carbon saturated with organic adsorption. The saturated activated carbon flows in the gasification cracking furnace for regeneration. It is divided into three stages from the furnace head to the furnace end of the gasification cracking furnace: drying stage: drying temperature 80‑150 °C , drying time 3min‑20min; desorption stage: desorption temperature 350‑700°C, desorption time 20min‑150min; activation stage: activation temperature 750‑1200°C, activation time 5‑150min; water vapor is introduced during the activation stage, The ratio of feed to activated carbon is 100‑500ml / min:1kg. The invention has the advantages of continuous production, high heat source utilization rate, stable activated carbon regeneration performance, high yield, no pollution and low labor intensity.

Description

technical field [0001] The invention relates to the technical fields of energy saving, environmental protection and resource regeneration, in particular to a regeneration technology for producing saturated activated carbon by utilizing waste heat of fuel oil combustion. Background technique [0002] Activated carbon has a highly developed pore structure and a large specific surface area, and is widely used in various industries. It can effectively adsorb harmful substances in water, such as organic matter and heavy metal ions, to purify wastewater. However, the high price of activated carbon makes it difficult to put activated carbon into practical application. In addition, activated carbon is also a product that consumes a lot of resources and energy. If the saturated activated carbon is not recycled, it will be a great waste of resources and will cause secondary pollution. [0003] At present, the technologies for regeneration of saturated activated carbon mainly include...
