Experimental Insights into the Fermentation of Pyro-Syngas to Ethanol in a Semi-Batch and Continuous Stirred Bioreactor with Mathematical Modelling and Optimization

Autor: Dinabandhu Manna, Ranjana Chowdhury, Rajnish K. Calay, Mohamad Y. Mustafa

Publikováno v: Energies, Vol 17, Iss 3, p 562 (2024)

Syngas fermentation can play an important role in implementing the concept of biorefinery as it can serve as a platform to convert high-lignin biomass to biofuels. For the utilization of this process in commercial scale, the generation of an experime

Parametric Sensitivity of CSTBRs for Lactobacillus casei: Normalized Sensitivity Analysis

Autor: Subhashis Das, Rajnish Kaur Calay, Ranjana Chowdhury

Publikováno v: ChemEngineering, Vol 4, Iss 2, p 41 (2020)

In this paper, a sensitivity analysis of a continuous stirred tank bioreactor (CSTBR) was conducted to determine a parametrically sensitive regime. The growth of a lactic acid bacterium, namely, Lactobacillus casei, in a pH-controlled CSTBR was consi

Studies on Pyrolysis Kinetic of Newspaper Wastes in a Packed Bed Reactor: Experiments, Modeling, and Product Characterization

Autor: Aparna Sarkar, Sudip De Sarkar, Michael Langanki, Ranjana Chowdhury

Publikováno v: Journal of Energy, Vol 2015 (2015)

Newspaper waste was pyrolysed in a 50 mm diameter and 640 mm long reactor placed in a packed bed pyrolyser from 573 K to 1173 K in nitrogen atmosphere to obtain char and pyro-oil. The newspaper sample was also pyrolysed in a thermogravimetric analyse
