Abstract
Agriculture biomass can be potently utilized in energy recovery schemes. Nutshell biomass generated in large amounts is a beneficial waste for its easy availability, least moisture content, low cost, high sturdiness, hardness and biodegradability. It can yield a range of value-added products when managed and treated properly. Gasification, Pyrolysis, Hydrothermal Carbonization, Incineration, melt extrusion or even composting are a few preferred techniques for treating nutshell waste. Compared to biochemical and Thermochemical techniques, Pyrolysis is an environment friendly treatment method to treat nutshells biomass waste that can lead to production of products such as Bio char, Bio oil and syngas. This paper focuses on identifying optimum parameters required for pyrolytic conversion and potential of selected nutshells. Aspen Plus simulation tool is employed to develop a steady-state model to predict the pyrolysis product yields of walnut shell waste. Proximate analysis, Ultimate analysis and Wet chemical analysis are input variables. The simulation results are helpful to estimate the possible product yields depending on reactor conditions and feedstock composition.
