Abstract: CO2 is the main source used in conventional radiocarbon dating to estimate the age of the archaeological wood. However, the production of CO2 by combustion for conventional radiocarbon dating normally produces minimal amounts of CO2,, making it difficult to proceed to subsequent processes. Thus, the objective of this paper is to introduce an integrated-combustion process on degraded wood that will maximize the production of CO2. Karas or Aqualaria Malaccensis was taken as case study. 23 response surface central composite design method was successfully employed for design of experimental (DOE) and analysis of the results. The number of experimental runs was determined using the Design-Expert 6.10.0. Karas wood was studied at different temperatures in a horizontal laboratory tubular quartz reactor. The effect of temperature, concentration of inert gas supplied during pyrolysis reaction and residence time taken during the production of CO2 from thermal and oxidative !
reactions were studied. The woods were pyrolysed in a thermogravimetry analyser (TGA) at different heating rates for the active pyrolysis occurrence. From the TGA results, it were observed that at lower temperature regime (less than 3000C) decompositon of wood, mainly H2O, CO2 and CO were evolved and at higher temperature regime, the main decomposition products were oil, H2O, hydrocarbon gases and lower concentration of CO and CO2. The results indicated that the production of CO2 increased with the continuous supply of oxygen at high temperature of pyrolysis and high flow rates of argon within a short period of residence time.
