Abstract
This work was carried out to study the potency of modified lampung-zeolite as catalyst for conversion of CO2/H2 into alcohol compounds. The zeolite was activated using 0.1N nitric acid, by soaking the zeolite in the acid for 2 h and then impregnated by Fe2O3 with varied content of 1 – 7% (g/g). To examine its activity, the catalyst was used in CO2/H2 conversion experiment at different temperatures (200 to 400 oC). The experimental results indicated the zeolite impregnated by iron ions exhibits catalytic activity, and the highest alcohol formation (26000 ppm) was achieved by 5% Fe2O3 doped zeolite at 200 oC. X-ray diffraction of washed-zeolite revealed that its crystalline phase is a clinoptilolite type of zeolite with monoclinic structure. Infra-red spectra analysis proved that 5% Fe2O3 doped zeolite has Bronsted-Lowry and Lewis acid sites presenting at wave number of 1466 and 1648 cm-1 respectively. Furthermore, SEM analysis implied that Lampung zeolite has a channel pattern and relatively good porous distribution.
