PENGIDENTIFIKASIAN ENTALPI BAHAN BAKAR PADAT (CHAR) DAN CAIR (TAR) HASIL PROSES PIROLISIS BIOMASA
Abstract: An experimental
study of pyrolysis method had been conducted to support alternative fuels
demand. It was very attractive method to convert the biomass; mahogany wood to
be the alternative fuels. For that reason, an appropriate pyrolyzer will be
required to support the process. Due to thermochemical process, an occurred
energy transfer all through the process considered not only the heat transfer
mechanism but also the chemical reaction mechanism producing heat of reaction
in the pyrolysis products (enthalpy). Therefore, the study aims to identify the
influence of different temperatures on the measured enthalpy of pyrolysis by
means of calorimetrical measurement. The biomass samples used mahogany wood
that would be pyrolyzed in the experimental run. Afterward, the influence of
temperature toward the solid (char) and liquid (tar) yields were investigated.
The enthalpy yields formation would be presented by calorific/heating value of
formed char/solid yields indicating important-physical properties of fuel. The
results referred that the values of solid yield enthalpy were pointed in the
increasing values with the increasing of pyrolysis temperature, however,the
enthalpy values of tar inclined to temperature of 500°C. It would decline
because the viscosity of tar becomes lighter.
