A new route was developed for the synthesis of renewable decalin with cyclopentanone which can be de- rived from lignocellulose. It was found that 1,2,3,4,5,6,7,8-octahydronaphthalene could be selectively pro- duced by the hydrogenation/dehydration/rearrangement of [1,1 \' -bi(cyclopentylidene)]-2-one (i.e. the self- aldol condensation product of cyclopentanone) over a dual-bed catalyst system. Among the investigated catalysts, the Ru/C and Amberlyst-15 resin exhibited the highest activities for the hydrogenation of [1,1 \' - bi(cyclopentylidene)]-2-one to [1,1 \' -bi(cyclopentan)]-2-ol and the dehydration/rearrangement of [1,1 \' - bi(cyclopentan)]-2-ol to 1,2,3,4,5,6,7,8-octahydronaphthalene, respectively. Using Ru/C and Amberlyst-15 resin as the first bed and the second bed catalysts, 1,2,3,4,5,6,7,8-octahydronaphthalene was directly pro- duced in high carbon yield (83.7％) under mild conditions (393 K, 1 MPa). After being hydrogenated, the 1,2,3,4,5,6,7,8-octahydronaphthalene was converted to decalin which can be used as additive to improve the thermal stability and volumetric heat value of jet fuel.
