Low chlorine oil production through fast pyrolysis of mixed plastics combined with hydrothermal dechlorination pretreatment

Yihan Wang et al.

Summary: The study found that high temperature, high gas flow rate, and small particle size promote the conversion of organic chlorine to inorganic chlorine during fast pyrolysis of mixed plastics. The optimal conditions for oil production were identified as 500℃ pyrolysis temperature, 40 ml/min carrier gas flow rate, and 0.1-0.15 mm particle size.

Transformation and kinetics of chlorine-containing products during pyrolysis of plastic wastes

Jing Pan et al.

Summary: The study investigated the migration and transformation of substances during the pyrolysis of PVC plastics using a thermogravimetric Fourier transform infrared mass spectrometry technology. Results showed that dehydrochlorination of PVC mainly occurred in the first stage, accompanied by the formation of conjugated double bonds and a small number of hydrocarbon compounds. Furthermore, the study suggested that by controlling the pyrolysis process, the generation of second pollutants can be minimized.

Study on the pyrolysis behaviors of mixed waste plastics

Dan Li et al.

Summary: Pyrolysis is a promising technology for recovering valuable hydrocarbons from waste streams. This study investigated three types of waste plastics and their mixed forms to explore thermal cracking features, products distribution, and kinetic features. Results showed differences in pyrolysis products and reaction processes among different types of plastics, with synergistic effects observed during co-pyrolysis processes.

Tracking the evolution of embryonic zeolites into hierarchical ZSM-5

M. Alonso-Doncel et al.

Summary: The use of organosilanes as mesopore generating agents produces hierarchical zeolites with enhanced accessibility and outstanding catalytic properties. The catalytic behavior of the embryonic zeolites for LDPE cracking is significantly affected by changes undergone during synthesis, showing increasing plastic conversion from 25 to 85%. Different types of evolving zeolite embryos are envisaged, exhibiting hybrid configurations and crystal growth proceeds partially hindered by grafted organosilane molecules, leading to the generation of globular particles with hierarchical porosity.
