The measured adsorption capacity of the natural zeolite clinoptilolite (a maximum of 0.12 mmol of total ions/g zeolite) was an order of magnitude lower than that observed for the two synthetic zeolites 13X and 4 A (a maximum of 2.9 and 1.65 mmol of total ions/g zeolite respectively).

Water removal from diesel, jet fuel and diesel/biodiesel blends was investigated using a highly crystalline natural zeolite, from the region of Eastern Macedonia and Thrace, Greece, as dehydration agent. For the evaluation of the zeolite performance an amount of 0.5% w/v of the material was mixed with the fuel for 2 h and then removed.

The natural zeolite was obtained from Jinyun, Zhejiang province, and its characteristics are shown in Table 1. Zeolite has a mean diameter of 3–5 mm which is similar to that of expanded clay used in control BAF, and the characteristics of expanded clay are shown in Table 2.

The performance of the BAF depends on the type of support media and its ability to meet objective of the treatment process. Natural zeolites, with properties such as ion …
