Using Nb2O5 as the catalyst, C10 olefin was prepared from C10 fatty alcohol via catalytic dehydration. Then the product was analyzed by IR method, and the presence of C=C was determined. When calcination temperature of the catalyst was 600 ℃, load capacity of Nb2O5 was 14%, reaction temperature was 290 ℃ and airspeed was 0.2 h-1, the dehydration rate of fatty alcohol reached the maximum value, the conversion rate of fatty alcohol reached the maximum value of 94%.
