Catalytic fast pyrolysis (CFP) of wood, woody residues, and agricultural waste has the potential to produce organic liquid intermediates that can be hydroprocessed sustainable aviation fuels (SAF). In this...

Issue: Pulp and paper industry were originally designed and constructed to use virgin wood feedstocks as a raw material. Some of the virgin wood fiber used for the pulp and paper industry is from lower value roundwood logs that are chipped for pulping. The other major source is from the residuals from sawmill, veneer, and lumber plants. These solid wood production plants produce millions of ton...

The possibility of using water insoluble fraction from biomass pyrolysis oil as additive in synthesis of Wood-Plastic novolac has been proved by using Differential Scanning Calorimetry (DSC) and Fourier Transformed Infra Red (FT-IR) spectroscopy. Synthesis of novolac with different concentrations (10, 20 and 30 wt %) of water insoluble fraction were performed. It was found that mechanical p...

Disposal of chrome tanned leather waste (CTLW) generated in leather processing industries has many environmental implications. This paper presents a double pyrolysis (PI & PII) method to dispose hazardous chrome tanned leather solid waste by converting it into useful products. When CTLW was subjected to double pyrolysis, three major products obtained were; (i) an energy enriched combustible gas...

This paper describes a kinetic study of the decomposition of waste printed circuit boards (WPCB) under conventional and microwave-induced pyrolysis conditions. We discuss the heating rates and the influence of the pyrolysis on the thermal decomposition kinetics of WPCB. We find that the thermal degradation of WPCB in a controlled conventional thermogravimetric analyzer (TGA) occurred in the tem...

S ince 2000, the worldwide market for carbon-fiber-reinforced composite materials (CFRP) has grown from 30,500 to 43,500 tons per year. According to the latest estimates, the demand for carbon fibers will rise to some 1,300,000 tons by 2020 [1]. When preforms are used for manufacturing CFRP parts by the Liquid Composite Molding (LCM) process, up to 40 % waste accrues, resulting in a considerabl...

The aim of the present work was to improve the C:O ratio in biomass by preserving the lignin macrostructure of lignocellulosic feed. The intention of liquid phase pyrolysis is to liquefy biomass and prepare biomass for further upgrading steps like hydrogenation and deoxygenation. Pyrolysis was carried out in a non-aqueous liquid phase heat carrier. The process was carried out in a semi-batch re...

Partial pyrolysis alters the chemical and textural properties of the lignocellulosic material. This work reports the effect of partial pyrolysis of olive wood on adsorption isotherms, kinetics and thermodynamics of chloro and nitrophenols. Shape of adsorption isotherms of the partially pyrolyzed sorbents was L3 for phenol; L2 for 2-nitrophenol and 2,4-dinitrophenol; H3 for 2-chlorophenol, 3-chl...
