Product Characteristics and Application Scope

Dewaxing molecular sieves can be used to separate n-alkanes (liquid paraffins) from branched alkanes and cyclic hydrocarbons by selective adsorption. Before F1, they were used in large-scale industrial separation of n-isoalkanes. The quality of dewaxed kerosene has excellent properties of low freezing point kerosene. The separated n-alkanes (paraffins) can be used as chemical raw materials for synthetic detergents.

Chemical formula: CasNa2 [(AlO 2)12 (SiO 2)12] * XH 20
