Thermal decomposition studies of 3-carene, a bio-fuel, have been carried out behind the reflected shock wave in a single pulse shock tube for temperature ranging from 920 K to 1220 K. The observed products in thermal decomposition of 3-carene are acetylene, allene, butadiene, isoprene, cyclopentadiene, hexatriene, benzene, toluene and p-xylene. The overall rate constant for 3-carene decomposition was found to be $$ \mathrm {k/s}^{-1}=10^{(9.95\,\pm \,0.54)}\; \exp (-40.88 \pm 2.71 \, \mathrm {kcal mol}^{\mathrm {-1}}/\text {RT}) . $$
