The synthesis of tetrahydrodicyclopentadiene (endo TCD) through continuous catalytic hydrogenation from dicyclopentadiene (DCPD) has been studied,and the Ni/ γ Al 2O 3 catalyst has been developed. Under the reaction conditions of w (DCPD)=20%～30% in hexane solution, SV=20～30 h -1 , p (H 2)=1 0 MPa and θ =150～160 ℃, DCPD conversion is more than 98% and endo TCD yield reaches 94%. The experimental results for synthesis of adamantane by catalytic isomerization of endo TCD using different synthetic zeolites show that only Y type zeolite with acid centers is fit for synthesizing adamantane. Effect of modification of the Y type zeolite catalyst on the isomerization of endo TCD has also been studied. The higher adamantane yield of 27 7% has been obtained by using 0 8%Pt 0 2%Re 3%Co/ReUSY under the conditions of n (cat)/ n (reactant)=0 25, p (H 2)=1.1 MPa, θ =250 ℃ and t =3 h.
