“…For these reasons, various catalyst systems have been studied such as zeolite and silica alumina 8 , noble metal, Pd/C 16 , USY zeolite 17 , natural and synthetic zeolite 18 , and aluminosilicate materials [19][20] . Aluminosilicate is of particular interest since this class of material can be produced with simple methods and from relatively cheap raw materials, and the composition, primarily Si/Al ratio, can be adjusted easily.…”

In this investigation, a mixture of sugarcane bagasse and rubber seed oil was subjected to pyrolysis for liquid fuel production, using aluminosilicates with different Si/Al ratios as catalysts prepared from rice husk silica and aluminum metal by electrochemical method. A series of pyrolysis experiments was conducted at the temperature range of 250 to 500 o C, with the main purpose to investigate the effect of the Si/Al ratios of the catalysts on the chemical composition of liquid fuels produced. The liquid fuels produced were analyzed using gas chromatography-mass spectrometry (GC-MS) technique for component identification. The experimental results show that the most intense production of liquid took place at the temperature range of 350 to 480 o C, while at lower temperatures gaseous product emerged as the main product. Analysis of the product using GC-MS technique revealed the presence of a series of compounds in the liquids, and broadly belongs to hydrocarbon, alcohol, ester, ketone, aldehyde, and acid. The results display significant effect of the catalyst composition on the composition of the liquids. The main trend observed is the tendency of increased the hydrocarbon content with decreased the Si/Al ratio of the catalyst, down to the ratio of 2.3 which produced liquid fuel with the highest hydrocarbon content 86%.

“…The limitations on recycling method and ever-increasing load on plastic waste has created a need for the development of alternative technologies to solve the problems associated with disposal. Greater interest was observed on the conversion of waste plastic into value added chemicals and fuel products in a range of published papers on conventional as well as microwave assisted pyrolysis [3], [7], [9][10][11][12]. The conventional method also known as traditional method converts waste into fuel products through thermal or catalytic pyrolysis.…”

Abstract. This paper presents an overview of advantages of microwave assisted pyrolysis of waste plastics together with its limitations. It has been established that microwave induced pyrolysis can be used to get value added chemicals and fuels through its numerous noted advantages in contrast to conventional pyrolysis. The process has the potential for fast, volumetric and selective heating of plastics for the recovery of energy. The limitation in the use of dielectric material as absorbent in plastic pyrolysis has been highlighted. Special focus has been given to the constraints encountered in the accurate measurement of temperature and uniform heating in microwave assisted pyrolysis. A new alternative method based on microwave-metal interaction in the pyrolysis of plastic waste has been presented. Further it has been realized that proper investigation and understanding of microwave process shortcomings is fundamental to the successful implementation of the technology and at the same time provide a sustainable environment in the endeavor for waste to energy mission.

When a GC/MS system is coupled with a pressurized reactor, the separation efficiency and the retention time are directly affected by the reactor pressure. To keep the GC column flow rate constant irrespective of the reaction pressure, a restrictor capillary tube and an open split interface are attached between the GC injection port and the head of a GC separation column. The capability of the attached modules is demonstrated for the on-line GC/MS analysis of catalytic reaction products of a bio-oil model sample (guaiacol), produced under a pressure of 1 to 3 MPa.
