Plastic waste upcycling toward a circular economy

In the current report, characteristics of the propagated wave in a sandwich structure with a soft core and multi-hybrid nanocomposite (MHC) face sheets are investigated. The higher-order shear deformable theory (HSDT) is applied to formulate the stresses and strains. Rule of the mixture and modified Halpin–Tsai model are engaged to provide the effective material constant of the multi-hybrid nanocomposite face sheets of the sandwich panel. By employing Hamilton’s principle, the governing equations of the structure are derived. Via the compatibility rule, the bonding between the composite layers and a soft core is modeled. Afterward, a parametric study is carried out to investigate the effects of the CNTs' weight fraction, core to total thickness ratio, various FG face sheet patterns, small radius to total thickness ratio, and carbon fiber angel on the phase velocity of the FML panel. The results show that the sensitivity of the phase velocity of the FML panel to the 
$${W}_{\rm{CNT}}$$

 and different FG face sheet patterns can decrease when we consider the core of the panel more much thicker. It is also observed that the effects of fiber angel and core to total thickness ratio on the phase velocity of the FML panel are hardly dependent on the wavenumber. The presented study outputs can be used in ultrasonic inspection techniques and structural health monitoring.

Characterization of the products obtained by pyrolysis of oil sludge with steel slag in a continuous pyrolysis-magnetic separation reactor

Catalysts can significantly affect the pyrolysis characteristics and products of oil sludge (OS). In this paper, we used TGA, a fixed-bed reactor, GC and GC-MS to obtain information. We found that ...

Effect of a calcium-based catalyst on the pyrolysis characteristics of oil sludge and its products

At present, oil sludge treatment modes include physical landfill, solidification, chemical incineration, solvent extraction and biomass treatment, and most treatment modes have the problems of secondary pollution, large investment, difficulty in industrialization and the like. Meanwhile, nearly hundred million tons of steel slag is discharged every year in China, and the utilization rate of the steel slag is only 20%; and the steel slag contains various metal elements, is a good catalytic material, and can reduce reaction activation energy and improve pyrolysis efficiency. The invention provides a novel method for acquiring recycled products of oil sludge and realizing steel slag recovery through low-temperature pyrolysis of oil sludge and steel slag. The pyrolysis of the oil sludge realizes obvious reduction in the steel slag; and compared with other treatment modes, the manner of pyrolysis is more environmentally friendly, and recycled products including pyrolysis coke, pyrolysis gasand pyrolysis oil can be obtained. Compared with a traditional steel slag treatment mode, a co-treatment mode of oil sludge pyrolysis and steel slag reduction has the advantages of high recovery rate, high grade and benefit for improving the steel slag utilization value. Experimental conditions in the invention are that the oil sludge is heated and softened and then mixed with the steel slag witha certain granularity according to a proper ratio, the formed mixture is placed on a continuous pyrolysis magnetic separation device and heated to a proper temperature, and proper standing time and magnetic field intensity of a magnetic separation tube are selected to obtain a high-quality pyrolysis oil gas product and high-grade reduced steel slag.
