Thermodynamic analysis of a high-yield Biochemical Process for biofuel production.
Bioresource technology, 2012Co-Authors: M. Imroz Sohel, Michael W. JackAbstract:This paper presents a thermodynamic analysis of a high-yield Biochemical Process for biofuel production from lignocelluosic biomass based on a previously proposed Process. Unlike the standard Biochemical Process, which ferments sugar intermediates to ethanol, the Process under consideration converts sugars to acetic acid which is esterified and hydrogenated to produce ethanol. This Process has a significantly higher yield and produces no carbon dioxide. However, we find that the thermodynamic efficiency of the Process is not increased in proportion to the yield gain. An additional survey of various biofuel production Processes showed no direct correlation between yield and thermodynamic efficiency. This survey and the detailed thermodynamic analyses lead us to conclude that yield alone is an unreliable performance metric for biofuel technologies.

Thermodynamic Analysis and Potential Efficiency Improvements of a Biochemical Process for Lignocellulosic Biofuel Production
Proceedings of the World Renewable Energy Congress – Sweden 8–13 May 2011 Linköping Sweden, 2011Co-Authors: M. Imroz Sohel, Michael W. JackAbstract:This paper presents a thermodynamic analysis of a Biochemical Process for the production of bioethanol from a lignocellulosic feedstock. The major inefficiencies in the Process are identified as: i) the combustion of lignin for Process heat and power production and ii) the simultaneous saccharification and fermentation Process. As lignin is not converted to ethanol and lignin has a high value of chemical exergy, the overall efficiency of the Biochemical Process largely depends on how the lignin is utilized. We therefore consider integrating a source of low temperature heat, such as waste heat or low-enthalpy geothermal heat, into a Biochemical lignocellulosic biorefinery to provide Process heat. This enables the lignin-enriched residue to be used either as a feedstock for chemicals and materials or for on-site electricity generation. Our analysis shows that integrating low temperature heat source into a biorefinery in this way represents an improvement in overall resource utilization efficiency.

Thermodynamic analysis of lignocellulosic biofuel production via a Biochemical Process: guiding technology selection and research focus.
Bioresource technology, 2010Co-Authors: M. Imroz Sohel, Michael W. JackAbstract:The aim of this paper is to present an exergy analysis of bioethanol production Process from lignocellulosic feedstock via a Biochemical Process to asses the overall thermodynamic efficiency and identify the main loss Processes. The thermodynamic efficiency of the Biochemical Process was found to be 35% and the major inefficiencies of this Process were identified as: the combustion of lignin for Process heat and power production and the simultaneous scarification and co-fermentation Process accounting for 67% and 27% of the lost exergy, respectively. These results were also compared with a previous analysis of a thermochemical Process for producing biofuel. Despite fundamental differences, the Biochemical and thermochemical Processes considered here had similar levels of thermodynamic efficiency. Process heat and power production was the major contributor to exergy loss in both of the Processes. Unlike the thermochemical Process, the overall efficiency of the Biochemical Process largely depends on how the lignin is utilized.

development and simulation of Biochemical reactor by using matlab
International Conference on Computer Modelling and Simulation, 2010Co-Authors: Arash Assadzadeh, S S JamuarAbstract:This research, an attempt has been made to develop and simulate a Process model to describe the Biochemical Process. Three important parameters that are desired to be controlled in the Biochemical reactor are pH, dissolved oxygen (DO) and temperature. In earlier Process model presented in literature, the effect of pH and DO change during Process implementation is not taken into account. In this research, the Biochemical reactor model was modified to include the effect of pH and DO with temperature. The new model contains those three parameters, which are mentioned before. The Biochemical reactor model was implemented in MATLAB Ver 7.5 by using an S-function.

A Review of Biochemical Process of Anaerobic Digestion
Advances in Bioscience and Biotechnology, 2015Co-Authors: K F Adekunle, Jude Awele OkolieAbstract:The search for alternative energy and fuels has motivated researchers to focus on renewable and sustainable means of getting them instead of relying on the conventional way of energy and fuel production. Anaerobic digestion is a Biochemical Process during which complex organic matter is decomposed in absence of oxygen, by various types of anaerobic microorganisms. The Process of Anaerobic digestion is appropriate for all waste water treatment systems given that the solid can be introduced to the system at an acceptable concentration. Biogas, the product of anaerobic di-gestion Process is a clean and renewable form of energy which can be a substitute for conventional sources of energy which are causing ecological-environmental problems and at the same time de-pleting at a faster rate. This paper reviews the anaerobic digestion Process and its complexities; it covers different stages involved in the Process, the substrate used in the Process, the relationship between the substrate and microorganisms and important operating parameters such as pH, temperature and loading rate.

Studies on wound healing potential of red pigment isolated from marine Bacterium Vibrio sp.
Elsevier, 2019Co-Authors: Pabba Shiva Krishna, S. Sudha, Fahad A. Al-dhabaan, Reddy Shetty Prakasham, Ashok K. Reddy, M. A. Singara CharyaAbstract:Wounds are common clinical entities of life which may be subacute or acute. Wound healing is a complex Biochemical Process where the cell structures are restored to normalcy, which depend on cell proliferation and migration, basically fibroblast cell. The present investigation was undertaken to evaluate the healing efficacy of red pigment isolated from marine isolate Vibrio sps on experimental wounds in albino rats. The red pigment was applied topically, twice daily for 14 days. Treatment with framycetin ointment was used as reference control. The red pigment treated group showed faster reduction in wound area in comparison with control and framycetin ointment treated groups. In conclusion, red pigment possesses significant healing potential in wounds and has a positive influence on the different phases of wound repair.
