Production of Green Aromatics and Olefins by Catalytic Fast Pyrolysis of Wood Sawdust

Production of Green Aromatics and Olefins from Lignocellulosic Biomass by Catalytic Fast Pyrolysis: Chemistry, Catalysis, and Process Development

Catalytic Pyrolysis of Willow Wood with Me/ZSM-5 (Me = Mg, K, Fe, Ga, Ni) to Produce Aromatics and Olefins

Biomass catalytic fast pyrolysis is one of the most promising technologies for the production of renewable aromatics and olefins directly from solid biomass. In this study, catalytic pyrolysis experiments were carried out on biomass in a fluidized bed reactor using typical metal-loaded (Mg, K, Fe, Ga, and Ni) ZSM-5 zeolites as catalysts. The effects of catalysts on the product distribution and ...

Aromatic Hydrocarbons Production from Catalysis of Douglas Fir Sawdust Pellets Pyrolysis Vapor over Zeolite Catalyst

The direct catalytic cracking of biomass pyrolysis vapor into aromatics derived from Douglas fir sawdust pellets was tested using an upfront microwave pyrolysis process coupled with a packed-bed catalysis process using a ZSM-5 Zeolite catalyst. A central composite experimental design (CCD) was used to optimize the bio-oil and syngas yields. The effects of temperature and inverse weight hourly s...

Synthesis, Characterization and Catalytic Activity of a New Chromium Catalyst Supported on Nanoporous MCM-41 for Oxidation of Olefins and Alkyl Aromatics

The mesoporous molecular sieve MCM-41 was covalently grafted with 3-chloropropyl trimethoxylsilane and then was reacted with [Cr(salpr)(H2O)]Cl, (salpr = N,N'-bis(3-salicylidenaminopropyl)amine) to afford MCM-41 containing Cr(salpr) moiety, Cr(salpr)MCM-41. Powder X-ray diffraction and nitrogen adsorption-desorption analyses revealed that not only the textural characteristics of the support wer...

Estimation of pyrolysis product of LDPE degradation using different process parameters in a stirred reactor

Pyrolysis of low density polyethylene (LDPE) by equilibrium fluid catalytic cracking (FCC) was studied in a stirred reactor under different process parameters. In this work, the effect of process parameters such as degradation temperature (420-510°C), catalyst/polymer ratio (0-60%), carrier gas type (H2, N2, ethylene, propylene, Ar and He), residence time and agitator speed (0-300 rpm) on the c...
