Barekati-Goudarzi, Mohamad published the artcileHeterogeneous and Homogeneous Components in Gas-Phase Pyrolysis of Hydrolytic Lignin, Recommanded Product: 4-Hydroxy-3-tert-butylanisole, the main research area is homogeneous gas pyrolysis hydrolytic lignin.
Pyrolysis of hydrolytic lignin (HL) in the newly designed, gas phase continuous droplet evaporation (CDE) and continuous atomization (CA) reactors, was studied. The products distribution was strongly dependent on the heterogeneous character of either delivery of lignin solution into CDE reactor (in-situ formation of solid phase) or sampling conditions using quartz wool in both CDE and CA reactors. The effect of residence time, initial concentration of HL solution and injection temperature on products distribution in CDE reactor was investigated and discussed in terms of mass and heat transfer limitation. The exptl. data confirm that at low initial mass delivery rates of lignin (micrograms per s) and by increasing initial lignin concentration (up to 40 times), the formation of phenolics is slightly intensified (6 times). However, the solid surface or any condense phase that forms in-situ during reaction in the gas phase may largely govern the pyrolysis processes. The detailed exptl. examination of homogeneous pyrolysis of lignin in both gas-phase reactors by implication of diverse anal. techniques (GC, GPC, LDI, FTIR, EPR, NMR) revealed break down of HL macromols. into oligomer-fragments after pyrolysis at negligible amounts of phenolics detected. A mechanistic interpretation of primary steps for formation of dominant intermediate products – oligomers and oligomer stable radicals, is represented.
