The key success factor of relationship marketing orientation was found to have indirect influences on banking performance effectiveness through the mediation of business strategies. These results add performance effectiveness and long-term relationships with bank customers (both retail and public enterprises) to the factors needed to respond to the highly competitive situation at present. Zeolite materials were represented by: sodalite, Na-X, Na-P1 and a mineralogical mixture of zeolites: Na-P1/Na-X/Linde-A (ZR), that results from the conversion of fly ash in hydrothermal conditions. They were derived using the technological line for the synthesis of zeolite materials. For the experiment a natural clinoptilolite was also used. To activate the sorption properties of tested materials, the zeolitic mixture ZR was calcined at temperatures of 200 °C to 600 °C for a period of 6 hours. Derived materials were analyzed by XRD and textual studies to determine the effect of activation on the sorption properties with respect to petroleum substances. For activation conditions up to temperature 400 °C and activation time 6h, all adsorption properties of the ZR material are increasing. BET surface area for the starting material is 116 m2g-1 for activated reaches up to 163 m2g-1. Other textural characteristics of the ZR also show an upward trend (surface area of micropores, volume and surface area of mesopores). Above temperatures 400 °C these parameters start to decrease. An activation temperature up to 400 °C causes an increase in the adsorption properties of ZR for both oils, the EkoDisel plus Orlen and biodiesel B100. Amount of adsorbed ekodisel oil was 1.48 [g/g sorbent] and for biodiesel was about 1.33 [g/g sorbent]. Study of the sorption capacity of petroleum substances were carried out by modified method of Westinghouse. The decrease of the adsorption properties above 400°C activation temperature is related to the instability of the crystal structure of the main component of the zeolite framework tested materials (mainly Na-P1). This is confirmed by the analysis of the mineral composition (XRD) of the activated materials, as well as a decrease of textural parameters.
