Co-pyrolysis of Polypropylene and Biomass

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2008
Abstract Polypropylene (PP) with biomass such as saw dust, rice husk, and corn cob were copyrolyzed in a fixed bed reactor at the temperatures of 450°C, 500°C, 550°C, and 600°C under nitrogen atmosphere. The effect of activated carbon as catalyst on pyrolysis liquid was also studied. The thermogravimetric behavior for two kinds of material was observed

The Co-Pyrolysis of Acetaldehyde and Propylene

Canadian Journal of Chemistry, 1973
Analysis of both major and minor products of the thermal reaction of mixtures of propylene and acetaldehyde over the temperature range 750–800 °K and at pressures below atmospheric show that both reactants initiate radical chains and that both addition and abstraction reactions of radicals with propylene are important.

Mixed biochar obtained by the co-pyrolysis of shrimp shell with corn straw: Co-pyrolysis characteristics and its adsorption capability

Chemosphere, 2021
The co-pyrolysis characteristics of shrimp shell (SS) with corn straw (CS) were investigated by comprehensive characterization to reveal the synergistic effects and further discuss the adsorption capability. TGA results showed that pyrolysis behavior and reactivity were improved with the increase of heating rate and doping ratio of CS. Flynn-Wall-Ozawa

Co-pyrolysis of microalgae and municipal solid waste: A thermogravimetric study to discern synergy during co-pyrolysis process

Journal of the Energy Institute, 2021
Abstract Synergism during the co-pyrolysis of microalgae (CC), municipal solid waste (MSW), and their blends (CC/MSW) (w/w %), 25/75 (CM-1), 50/50 (CM-2), and 75/25 (CM-3), was evaluated based on thermal decomposition pattern, evolved gases, rate and extent of thermal decomposition, and kinetic parameters.

Co-pyrolysis characteristic of biomass and bituminous coal

Bioresource Technology, 2015
Co-pyrolysis characteristics of biomass and bituminous coal have been studied in this work. The temperature was up to 900°C with the heating rates of 10, 15, 20, 25 and 30°C/min. Rice straw, saw dust, microcrystalline cellulose, lignin and Shenfu bituminous coal were chosen as samples. Six different biomass ratios were used.

Co-pyrolysis of sewage sludge and cotton stalks

Waste Management, 2019
Proper disposal of ever-increasing amounts sewage sludge and cotton stalks is a challenge around the world, and conversion of these wastes into biochars via co-pyrolysis may be a promising solution. In this study, biochars were prepared via co-pyrolysis of sewage sludge and cotton stalks with different mixing ratios (cotton stalks/sewage sludge, w/w ...

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 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

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.

Co-pyrolysis of oily sludge and algal biomass

Journal of Environmental Management
Alternative fuels have attracted rising attention as sustainable energy options due to mounting pressures to lower greenhouse gas emissions and decrease dependence on fossil fuels. This study investigates the co-pyrolysis of oily sludge (OS), a petroleum refinery residue, and algal biomass (AB), a biological waste stream rich in organic content from ...
