Co-Pyrolysis Characteristics and Kinetic Analysis of Oil Sludge with Different Additives

Co-pyrolysis characteristics of long flame coal mixed with duckweed in different proportions were studied by using TG. And the kinetic parameters was also figured out by using the method of Coats-Redfern. It was exhibited significant synergistic effect created more the light component between duckweed and coal during co-pyrolysis, The pyrolysis rate of flame coal is much smaller than biomass, and the starting pyrolysis temperature of flame coal is higher than biomass. The kinetic analysis indicated that the pyrolytic processes can be described as first order reactions model. The average activation energy of duckweed and coal was 39.14kJ/mol and 46.43kJ/mol , and with the increasing of the duckweed proportion, pyrolysis activation energy was decreased.

The pyrolysis characteristics of oil sludge and coal mixed fuel in an argon atmosphere were studied by thermogravimetric analyzer. Factors that affect the pyrolysis process were analyzed. The pyrolysis mechanism equation of the oil sludge and coal fuel was determined. Hereafter, the dynamic properties were provided, namely the activation energy and frequency factor. In this paper, pyrolysis of the mixture occurs in six distinct steps, each accompanied by its unique reactionary mechanics. The activation energy at each step increased with respect to temperature (presenting an initial increase and subsequent decrease). as the rate of temperature increase was amplified, each respective step has its activation energy slightly reduced. Moreover, the mixture shows the influence of non-linear relationships during pyrolysis.
