Synthesis of 4A Zeolite from Coal-series Kaolin;

The application and research on“double 90” calcined coal-series kaolin in China were introduced in this paper,some opinions about its development were given.

The potassium acetate is intercalated into layers of kaolin quickly and kaolin-potassium acetate intercalated complex is prepared by grinding the mixture of coal-series kaolin from Datong, Shanxi, potassium acetate and a little water and drying them.

Synthesis of P molecular sieve from coal series kaolinite by calcination twice and hydrothermal reaction;

Synthesis of 4A zeolite as detergent from coal series kaolinite;

PSC continuous modification equipment for coal series kaolin powder;

Coal series kaolin from Pingxiang was used as raw material to prepare intercalation compound of kaolinite and potassium acetate by the soaking method.

This article gave some main research results on the modification methods of Huaibei coal series kaolin,including calcination and modification of the ore sample,selection of coupling agent and surface active agent available in the modification.

, the experiment of assisted grinding was done in superfine grinding of coal measures kaolin.

To take coal measures kaolin in Jiaozuo area as raw material,carried out mineral composition and content analyses,studied impacts on whiteness from additive kind and dosage,inlet material grain size,calcining time and calcining temperature etc.
