Abstract

The production process includes reduction, filtering, washing, sieving, filtering and drying steps. In the reduction inside the reduction reactor with paddle stirrer, iron powder, water and reacted medium are heated with steam for 0.5-1 hr to activate, organic material is dropped continuously, iron powder, water and reacted medium are replenished intermittently to maintain the proper material ratio, and the suspension of organic product and iron mud is discharged continuously from the discharge port. The present invention is one continuous production process with low material consumption and high resource utilization.

Description

technical field

[0001] The invention relates to a method for producing iron oxide black, in particular to a method for synchronously producing iron oxide black by using an iron powder reduction method to produce organic products. Background technique

[0002] The reduction reaction of producing organic products with iron powder reducing agent is a traditional reduction process. The process has the characteristics of simplicity, low equipment requirements, and few side reactions. Finally, the iron powder is oxidized by organic raw materials into iron oxide (mainly composed of ferric oxide and ferric oxide adduct). The production method is low in production efficiency, and the iron sludge generated is of low grade and is often discarded, which is easy to cause waste of resources and environmental pollution. Contents of the invention

[0003] The object of the present invention is to propose a method for producing o...
