Pine bark over this is just considered waste that pollutes the environment, pine bark is biomass which can be processed into alternative energy. Through the method of catalytic pyrolisis using the CoMo/NZA expected to convert pine bark as biomass into bio-oil. On the study of biomass pine skin 50 gram with a size of -60+80 mesh, silinap 500 ml, and catalyst CoMo/NZA 1,5 grams are incorporated into the slurry reactors, then pyrolysis process carried out on operating conditions, namely temperature and stirring speed 300 3200C rpm for 120 minutes with a flowing nitrogen gas (N2) as protective gas. The results obtained indicate that the yield obtained at optimum catalyst 1% CoMo/NZA i.e. amounting to 51,7%. Physical properties of test results obtained indicate the density (0,919 gr/ml), the viscosity (8.02 pm cSt), numbers of acidity (17, 78a), flash point (50 0 c) and the heat (44, 04MJ/Kg).Analysis of chemical content of results with GC-MS, the predominant chemical components found in bio-oil is 1-Pentene 13.90%, 2-Pentene 10.65%, 1-Propene, 1-Pentene 9,46% 6,38%, Hexane 6,23%.
