Use of plastic waste as a fuel in the co-pyrolysis of biomass: Part II. Variance analysis of the co-pyrolysis process

Journal of Analytical and Applied Pyrolysis, 2014
Abstract The aim of our study described in this article was statistical evaluation of the influence of process conditions on the chemical and physical properties of products obtained from biomass and plastic waste co-pyrolysis. To estimate the effects of the process conditions on the chemical and physical properties of products, analysis of variance (

Co-pyrolysis of microalgae and plastic: Characteristics and interaction effects

Bioresource Technology, 2019
To improve the quality of the oil produced from microalgae, the co-pyrolysis of low-density polyethylene (LDPE) and Nannochloropsis sp. (NS) in a fixed bed reactor was investigated at different mixing ratios. Co-pyrolysis improved the gas yield, and the lower heating value of the gas products increased obviously with an increase in the LDPE amount ...

Co-pyrolysis of Chinese lignite and biomass in a vacuum reactor

Bioresource Technology, 2014
A vacuum fixed bed reactor was applied to pyrolyze lignite, biomass (rice husk) and their blend with high temperature (900 °C) and low heating rate (10 °C/min). Pyrolytic products were kept in the vacuum reactor during the whole pyrolysis process, guaranteeing a long contact time (more than 2 h) for their interactions.

Co-pyrolysis of polypropylene waste with Brazilian heavy oil

Journal of Environmental Science and Health, Part A, 2011
To evaluate the chemical recycling of plastic residues, co-pyrolysis of polypropylene (PP) waste with Brazilian crude oil was evaluated varying the temperature (400°C to 500°C) and the amount of PP fed to the reactor. The co-pyrolysis of plastic waste in an inert atmosphere provided around 80% of oil pyrolytic, and of these, half represent the fraction

Effect of lignin on the co-pyrolysis of sludge and cellulose

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2016
ABSTRACTIn order to investigate the role of the lignin in the co-pyrolysis process of the sludge and the cellulose, the co-pyrolysis process was carried out in a thermogravimetry analyzer. The result shows that when the proportion of the sludge:cellulose:lignin was 1:1:0.4, the main co-pyrolysis temperature range was narrower, the ultimate pyrolysis ...

Co-pyrolysis behaviors of energy grass and lignite

Energy Conversion and Management, 2015
Abstract A kind of energy grass (giant reedgrass) with high calorific value, high production, low land requirement and low sulfur dioxide emission is introduced into lignite pyrolysis process in this paper. Individual pyrolysis and co-pyrolysis characteristics of energy grass and lignite are investigated by the thermogravimetric analyzer together ...

Kinetic analysis of co-pyrolysis of cellulose and polypropylene

Journal of Thermal Analysis and Calorimetry, 2014
The present research work focuses on understanding the kinetics and mechanism of co-pyrolysis of cellulose, a major constituent of biomass, and polypropylene (PP) that is abundantly present in waste plastics. Co-pyrolysis of cellulose and PP of different compositions, viz., 100:0, 80:20, 60:40, 40:60, 20:80, and 0:100 (mass%/mass%), was carried out in ...

Co-pyrolysis of pine cone with synthetic polymers

Fuel, 2010
Abstract Biomass from pine cone (Pinus pinea L.) was co-pyrolyzed with synthetic polymers (PE, PP and PS) in order to investigate the effect of biomass and plastic nature on the product yields and quality of pyrolysis oils and chars. The pyrolysis temperature was of 500 °C and it was selected based on results from thermogravimetric analysis of the ...

Enhancing the stability and heavy metal immobilization of co-pyrolysis biochar through biomass and red mud co-pyrolysis: A synergistic mechanism

Journal of Environmental Management
In the research on the preparation of biochar from co-pyrolysis of red mud (RM) and biomass, the synergistic mechanism of immobilizing heavy metals (HMs) and enhancing the stability of biochar is seldom reported. In this study, the effects of different mass ratios of corn stalks (CS) and RM (9:1, 3:1, 2:1, 1:1) and pyrolysis temperatures (300 °C, 450 ...
