    Abstract: Kaolinite clay has low cation exchange capacity and small surface area; it has rarely been used as adsorbent. As well as, green, low cost and efficient adsorbent is desired. Modification of kaolinite is necessary to improve its adsorption capacity. Jordanian kaolinite has been modified by humic acid (HA) through batch adsorption mode. Two types of ... Show More

    Abstract: Ketonisation of pentanoic acid over bulk cobalt-molybdenum and its supported catalysts in the gas-phase was investigated using a fixed bed reactor under atmospheric pressure at 320-420°C. Compared to other supported catalysts, 20% Co-Mo/Al2O3 demonstrated the best catalytic performance and stability giving to give 95% 5-nonanoe selectivity at 91% p... Show More
