Co-pyrolysis of lignin and polyethylene with the addition of transition metals - Part I: Thermal behavior and kinetics analysis

Facile and green preparation of solid carbon nanoonions via catalytic co-pyrolysis of lignin and polyethylene and their adsorption capability towards Cu(ii)

“…The preparation of feedstock and CNOs was in accordance with our previous study. 23,24 In brief, transition metal-loaded LG was rstly prepared by impregnation method, followed by blending PE with the transition metal-loaded LG using an agate mortar. The metal-loaded LG/PE mixture with different types of transition metals and different contents of Ni was readily collected accordingly.…”

Coked Ni/Al2O3 from the catalytic reforming of volatiles from co-pyrolysis of lignin and polyethylene: preparation, identification and application as a potential adsorbent

“…The co-pyrolysis sample was pretreated according to the procedure described in the literature. 6 In brief, lignin was firstly impregnated in nickel nitrate solution, and then blended with polyethylene powder after drying overnight. The concentration of metallic Ni in the co-pyrolysis sample was 1 mmol/g and the ratio of lignin and polyethylene was 1:1.…”

“…1 Co-pyrolysis is considered as a promising technique for converting solid wastes into value-added products, and adding catalyst in the pyrolysis process can further enhance the conversion efficiency of feedstock and the yield and selectivity of target products. [2][3][4][5] Catalyst can be blended with the raw materials directly, 6 or located under the raw material to catalyze the pyrolysis volatiles, 7 which has different influences on the formation of products. In addition, the effects of catalytic temperature, the ratio of feedstock to catalyst, the properties of catalyst and other parameters on the distribution of products are important for catalytic co-pyrolysis of solid wastes.…”

Characterisation and composition identification of waste-derived fuels obtained from municipal solid waste using thermogravimetry: A review

“…Heating rate affects the range of decomposition temperature of the sample ( Marsh et al, 2007 ; Park et al, 2012 ; Slopiecka et al, 2012 ; Wang et al., 2020 ; Yurdakul and Atimtay, 2015 ). Increased heating rates result in higher decomposition temperatures and higher rates of mass loss due to the changes in activation energy and/or different heat dissipation rates ( Conesa and Rey, 2015 ; Lin et al, 1999 ; Park et al, 2012 ; Quan et al, 2016 ; Yang et al, 2001 ; Yurdakul and Atimtay, 2015 ).…”

“…Interactions among biomass components ( Akubo et al, 2019 ; Cabeza et al, 2015 ; Hosoya et al, 2007 ; Jaffar et al, 2020 ) and between biomass and fossil-based plastics ( Özsin et al, 2019 ; Wang et al, 2020 ) were identified through kinetic and compositional analysis of pyrolysis products using TGA–EGA. Zhao et al (2018) reported that the presence of lignin reduced the pyrolysis rate of cellulose, whereas the presence of cellulose and hemicellulose promote the production of more phenolic substances during lignin pyrolysis.…”
