Investigation on catalytic pyrolysis of pine sawdust: Catalyst screening by Py-GC-MIP-AED

Comparative analysis of pyrolysate from herbaceous and woody energy crops by Py-GC with atomic emission and mass spectrometric detection

“…Py-GC-AED has been extensively applied to study the pyrolytic behaviour of pine sawdust and the effects of catalysis by metal oxides on pyrolysis product. In these studies pyrolysis products were distinguished by volatility [12,13].…”

“…An important fraction of pyrolysate ending up into bio-oil is precluded to GC analysis due to the low volatility of its constituents, such as pyrolytic lignin and oligosaccharides. Nevertheless, the yield of this non-volatile matter (NVM) could be roughly estimated in concomitance with Py-GC-AED from the weight determination of the residue left after pyrolysis [12,13].…”

Analytical Techniques as a Tool to Understand the Reaction Mechanism

“…Various inorganic compounds can be added to biomass samples in order to enhance the yield of a certain product and reduce the number of the pyrolysis products [104,105]. Catalytic conversion is discussed in a separate chapter.…”

Catalytic Vapor Cracking for Improvement of Bio-Oil Quality

“…They concluded that acetic acid was firstly converted to ethyl acetate, subsequently transformed into acetone which would be finally decomposed to gaseous products, mainly CO and CO 2 . Torri et al [85] performed a screening study using 31 catalysts (MCM-41 supported metal oxides, bulk metal oxides, clays, zeolites and methanol synthesis catalysts) by Py-GC coupled to microwave induced plasma and atomic emission detector (Py-GC-MIP-AED) to assess their activities in the catalytic pyrolysis of biomass. They reported a slight decrease in bio-oil yield, but a significant decrease in non-volatile fraction over ZnO, CuO, Fe 2 O 3 and methanol synthesis catalysts.…”
