Abstract:

This study investigated the production of pyrolytic oil from cassava peel wastes. Pyrolysis is a very important thermochemical method for converting biomass into biofuel. In recent times, the production of biofuel has taken center stage due to concerns over the sustainability of conventional energy sources. Pyrolysis has received much attention by researchers because it can be used to optimize the production of high calorific value pyrolytic oil. A fixed bed pyrolysing unit was constructed for the production of liquid fuel in this study. Cassava peels were pyrolysed in the reactor. The tempera

Abstract:

Environmental management through effective utilization of biowastes has been a topic of intensive research in recent years. This study examines the effect of pyrolysis temperature on the physical and morphological characteristic of biochar (BC) derived from lignocellulosic wastes. The biochar was prepared by pyrolysing date palm biomass at various temperatures, i.e., 300, 400, 500, 600, and 700 °C. These pyrolysed biochars were then characterized for their carbon content, mineral compositions, chemical functionalities, and morphological structures, for understanding their physicochemical chara

Using agricultural waste biomass pyrolysis to produce energy sources and biochar may support local economies in rural areas and enhance sustainability in the agricultural sector, reducing dependence on traditional energy sources and fertilisers. To obtain liquid and gaseous forms of biomass fuel, wheat straw pellets were pyrolysed in a screw reactor at temperatures of 300, 400, 500, 600, and 700 °C. An analysis was conducted to assess the influence of process temperature on the physicochemical composition of the raw material and the resulting biochar, pyrolysis liquid, and synthesis gas. The p

Abstract:

Abstract Pyrolysis together with gasification and combustion create a group of so called thermic processes. Unlike the combustion it is based on thermic decomposition of organic materials without any access of oxidative media. Within the pyrolytic process, three main fractions are created: solid residue, pyrolytic gas and organic liquid product - pyrolytic oil. The presented article examines the effects of pyrolysis operational conditions (above all, temperature) on gas products, solid residues and liquid fractions.

Abstract:

CW CO2 laser photosensitized (SF6) homogeneous pyrolysis of n-alkanes (C5-C7) affords almost twice higher yield of important ethylene compared to conventional pyrolysis in tubular reactors. No production of heavy pyrolytic oils, resins or coke and very small alteration of the pyrolytic distribution with the conversion are other advantages of the laser process that can be ascribed to the absence of in conventional reactors important surface reactions.
