n-Butanol conversion to hydrocarbons over H-ZSM-5, H-ZSM-11, H-L and H-Y zeolites at 300-400 degrees C using a fixed bed flow reactor has been studied. It was shown that all studied H-zeolites provide 100% alcohol conversion at T >= 300 degrees C. The conversion products are liquid hydrocarbons C5-10, gaseous hydrocarbons C-<5 and water. Their weight ratios are equal to 1:0.4:0.4 for H-ZSM-5 and 1:0.6:0.5 for H-Y (at 350 degrees C). The yield of liquid hydrocarbons over the H-pentasils is higher (52-55 wt.%) than over large pore H-L and H-Y (43-48 wt.%). The liquid fraction obtained over H-ZSM-5 includes aromatics mainly whereas on H-Y-olefins. It was shown that H-ZSM-5 (Si/Al = 20) is capable to provide the yield of liquid hydrocarbons on the level of 50-55 wt.% from spent alcohol at load on a catalyst up to 20 mmol C4H9OH g(cat) (1) h (1).
