Co‐pyrolysis of waste polymers with coal

Macromolecular Symposia, 1998
AbstractCo‐pyrolysis of coal with waste polymers in a stationary quartz reactor was performed. Mass balance of the process was evaluated and properties of products were characterized. The main product (solid carbonaceous residue) exhibits low ash and sulfur contents and, from the point of view of application, satisfactory surface properties. Therefore,

Co-pyrolysis of cellulose/lignin and sawdust: Influence of secondary condensation of the volatiles on characteristics of biochar

Energy, 2021
The major compounds of cellulose and lignin in biomass could have varied contributions on distribution and properties of pyrolysis products by generating the volatiles of different structures via pyrolysis. In this paper, the co-pyrolysis of cellulose or

Co-Pyrolysis of Biomass with Plastics

1997
The recycling of plastics for further uses as raw material is proving to be difficult due to reluctance of relatively conservative industry to receive them, particularly because of high costs involved in recycling and the lack of incentives. The incineration of these plastics is a controversial issue, mainly resulting from the concern in protecting the

Thermo-catalytic co-pyrolysis of biomass and high-density polyethylene for improving the yield and quality of pyrolysis liquid

Energy, 2021
The overall goal of this research was to study the effects of temperature and pine-to-HDPE ratios on the pyrolysis products. Catalytic co-pyrolysis of pine and HDPE was carried out in a double-column staged reactor, wherein the temperature was varied as ...

Thermal behaviour and kinetic study of co-pyrolysis of microalgae with different plastics.

Waste Management, 2021
The coexistence of plastics and microalgae in the ocean has brought great challenges to the environment. Therefore, co-pyrolysis of microalgae Dunaliella salina (DS) and typical plastics (polypropylene (PP), polystyrene (PS), polyethylene terephthalate ...

Analysis of Pyrolysis Index and Reaction Mechanism in Microwave-Assisted ex-situ Catalytic Co-Pyrolysis of Agro-residual and Plastic Wastes.

Bioresource Technology, 2022
Catalytic and non-catalytic microwave-assisted co-pyrolysis of biomass with plastics was performed to understand the interactions. An ex-situ configuration was adopted for performing catalytic co-pyrolysis experiments with ZSM-5 as a catalyst.

Catalytic co-pyrolysis of herb residue and polypropylene for pyrolysis products upgrading and diversification using nickel-X/biochar and ZSM-5 (X=iron, cobalt, copper).

Bioresource Technology, 2022
It is very important to find cheap and efficient catalysts for catalytic co-pyrolysis. Catalytic co-pyrolysis of herb residue (HR) and reused polypropylene (PP) using Ni-X/biochar and ZSM-5 (X=Fe, Co, Cu) was performed to produce pyrolysis oil, pyrolysis

Acceleration of cellulose co-pyrolysis with polymer

Polymer Degradation and Stability, 2001
Abstract This study was conducted for greater clarification of pyrolysis of municipal solid waste. The pyrolysis of pure cellulose, polyethylene (PE), polypropylene (PP), polystyrene (PS), poly(vinyl chloride) (PVC), and poly(vinylidene chloride) (PVdC) was compared with that of mixtures of these compounds by thermal analysis.
