The catalytic copyrolysis of waste particle board (WPB) and polypropylene (PP) was investigated for the first time over HY (5.1), HY (30), H-Beta and Ga/H-Beta catalysts. The catalysts were characterized by BET and NH3-TPD analyses. The catalytic pyrolysis of the WPB increased the production of...

Catalytic fast pyrolysis over HZSM-5 of red pepper stems, a representative agricultural residue material in the southern area of South Korea, was carried out. The SiO2/Al2O3 ratio of the catalyst were 23 and 280. Pyrolysis-gas chromatography/mass spectrometry was used to pyrolyze the pepper stem...

The hydrodeoxygenation of 2-methoxy phenol and dibenzofuran, which are representative model compounds of bio-oil, was performed using two different Pt/mesoporous zeolite catalysts, Pt/mesoporous Y and Pt/mesoporous MFI. The reforming of 2-methoxy phenol and dibenzofuran via catalytic...

Catalytic pyrolysis of particle board, a type of waste wood that is increasingly produced all over the world, was carried out over three types of zeolite catalysts: HBETA, HZSM-5, and Ga-impregnated HZSM-5 (Ga/HZSM-5). Experiments conducted using a batch reactor showed that the bio-oil yield and...

The catalytic pyrolysis of Laminaria japonica was carried out over four different microporous zeolite catalysts, HZSM-5 (SiO2/Al2O3 = 23, 80), HBETA (SiO2/Al2O3 = 25) and HY (SiO2/Al2O3 = 30). The effects of the catalysts on the properties of the resulting pyrolysis products were examined....

Threat of global warming and imminent exhaustion of fossil fuels call for development of alternative carbon-neutral energy sources. Among others, bio-oil, which can be produced from various biomass, can be used not only as an alternative fuel but also as a feedstock for production of high-value...

Considerable attention has been given to development of renewable energy due to imminent exhaustion of fossil fuels and environmental concerns over global warming. Bio-oil is recognized to be a promising alternative energy source because many different kinds of biomass, including agricultural...

The pyrolysis characteristics of construction waste wood were investigated for conversion into renewable liquid fuels. The activation energy of pyrolysis derived from thermogravimetric analysis increased gradually with temperature, from 149.41 kJ/mol to 590.22 kJ/mol, as the decomposition of...
