“…[11][12][13] Co-gasification with biomass has also been reported to assist the feeding of gasification of plastics into the gasifier. [14][15][16] In addition, plastics pyrolysis has also been used to produce carbon nanotubes (CNTs), a high-value product having extraordinary physical and chemical properties, by either mixing plastics with catalyst in a single reactor, 17,18 or passing the pyrolysis products of plastics into a second stage catalyst reactor. 19,20 Both product yield and the properties of CNTs are basically determined by the raw materials, for example, CNT production has been investigated from laser ablation, plasma assisted deposition, pyrolysis or chemical vapour deposition.…”

Producing both hydrogen and high-value carbon nanotubes (CNTs) derived from waste plastics is reported here using a pyrolysis-reforming technology comprising a two-stage reaction system, in the presence of steam and a Ni-Mn-Al catalyst. The waste plastics consisted of plastics from a motor oil container (MOC), waste commercial high density polyethylene (HDPE) and regranulated HDPE waste containing polyvinyl chloride (PVC). The results show that hydrogen can be produced from the pyrolysis-reforming process, but also carbon nanotubes are formed on the catalyst. However, the content of 0.3 wt.% polyvinyl chloride in the waste HDPE (HDPE/PVC) has been shown to poison the catalyst and significantly reduce the quantity and purity of CNTs. The presence of sulphur has shown less influence on the production of CNTs in terms of quantity and CNT morphologies. Around 94.4 mmol H 2 g -1 plastic was obtained for the pyrolysis-reforming of HDPE waste in the presence of the Ni-Mn-Al catalyst and steam at a reforming temperature of 800 °C. The addition of steam in the process results in an increase of hydrogen production and reduction of carbon yield; in addition, the defects of CNTs e.g. edge dislocations were found to be increased with the introduction of steam (from Raman analysis).

“…Within this range of temperature, the water gas shift reaction, refer to (11), was probably one of the most important reactions defining the final gas composition. While the average bed temperature of 10% and 20%SPB in the fuel mixture increased to 750-800°C at ER in the range of 0.26-0.43, the forward reaction of water gas reaction and Boudouard reaction, refer to (9) and (10), were favored resulting in the reduction of CO 2 formation and increasing of CO and H 2 production [12], [21]. The production of CH 4 and C 2 H n also increased as the weight proportion of SPB increased in the fuel mixture for all ERs due to the plastic cracking, rather than the methanation reaction [22].…”

“…Considering the vast amount of plastic waste generated and its high heat content with low-moisture content, plastic bag after being separated from MSW can be considered as a high quality fuel. However, gasification of pure plastic waste has been shown to have some operational problems such as difficulties in feeding and technical limitations due to melting [12] and therefore plastic wastes are often co-processed with other fuels, [12]- [15].…”

Abstract-With an increased interest in energy production from biomass through gasification, the properties of biomass that influenced gasification performance have been investigated. One of important properties is the moisture content. Generally, the excessive moisture in biomass is reduced to meet the acceptable level for gasification by an additional pretreatment process which always costs extra investment. One possible alternative is the co-processing of high-moisture biomass fuels with other low-moisture fuels. In this study, the utilization of plastic waste to solve the problem of high-moisture biomass gasification was investigated by mixing the high-moisture rubber woodchip (27%M.C.) with plastic waste at various mixing ratios. The results showed a significant improvement of gasification performance. Even at 10% mixing ratio, the higher heating value of the product gas increased by about 50% and 25% compared to the case of high-moisture rubber woodchip (27%M.C.) and pre-dried rubber woodchip (8.5%M.C.), respectively. Compared to mixing with rubber waste at the same weight ratio, the plastic waste addition was found to give a better gasification improvement largely due to the higher carbon and hydrogen content in plastic waste. The findings from this study have shown not only that the high-moisture biomass can be used without pretreatment needed, but also an effective solution to plastic waste disposal.

“…The need for alternative fuels has lead for the co-gasification of PSW with other types of waste, mainly biomass. Pinto et al (2002Pinto et al ( , 2003 studied the fluidized bed co-gasification of PE, pine and coal and biomass mixed with PE. Xiao et al (2009) co-gasified five typical kinds of organic components (wood, paper, kitchen garbage, plastic (namely PE), and textile) and three representative types of simulated MSW in a fluidized-bed (400-800 0 C).…”
