Thermodynamic analysis of hydrogen production from ethanol-glycerol mixture through dry reforming

Z.Y. Zakariaa,*, M. Jusoha, A. Joharia, M.A.A. Zainia, F.H. Kasimb

Thermodynamic properties of ethanol-glycerol dry reforming have been studied with the method of Gibbs free energy minimization for hydrogen production from ethanol-glycerol mixture. Equilibrium compositions were determined as a function of CO2/ethanol-glycerol molar ratios (CEG)(1:1-12:1) where ethanol-glycerol is 1:1; reforming temperatures (573-1273 K) at different pressures (1-50 bar). Optimum conditions for hydrogen production are temperatures between 1073 and 1273 K and CEG of 1:1 at 1 bar pressure, whereas temperatures above 1073 K and CEG ratio 1:1 and 1 bar are suitable for the production of synthesis gas. Higher pressure and higher CEG ratio does not encourage hydrogen formation. Under identified optimum conditions, carbon formation can be thermodynamically inhibited

Keywords: ethanol-glycerol mixture, dry reforming, hydrogen production, synthesis gas production

THERMODYNAMIC STUDY OF CATALYTIC CONVERSION OF GLYCEROL STEAM REFORMING TO OLEFINS

Executive Summary of Research Proposal

Glycerol, an alcohol and oxygenated chemical byproduct from biodiesel production, has enormous potential to be converted into higher value-added fuels and chemicals. Due to the alarming excessive production of glycerol worldwide that have triggered environmental concerns, and the importance of olefins in the industry, it is therefore essential to explore the process of glycerol-to-olefin (GTO) in greater depth. This is mainly due to the fact that no dedicated study concerning GTO has been performed. Detail catalytic study has been previously studied and results are promising. However, there is a need to explore GTO in bigger perspective. In order to pursue this, complex thermodynamic analysis via simultaneous dehydration, dehydrogenation and deoxygenation of glycerol at various temperature, pressure and flowrate will be investigated. Empiral models will be used to generate thermodynamic data analysis. The result from this study will be a novel thermodynamic analysis of catalytic conversion of glycerol to olefins via complex reaction network.

DEVELOPMENT OF NEW SUSTAINABLE ACYL ACCEPTOR FOR BIODIESEL PRODUCTION FROM PFAD

Executive Summary of Research Proposal (PY/2014/02061)

Biodiesel is a clean burning fuel produced from renewable domestic sources such as vegetable oils and animal grease. It is biodegradable, non-inflammable,
non-toxic and has a favorable combustion–emission profile, producing much less carbon monoxide, sulfur dioxide and unburned hydrocarbons than
petroleum-based diesel. The production of first generation biodiesel has grown tremendously over the past decade. InMalaysia’s context, the government has
encouraged the production of biodiesel by providing numerous incentives. In 2006, 60 biodiesel manufacturing licenses were approved. Unfortunately, almost all
biodiesel plants utilizing vegetable oil as feedstock were later forced to shut down their operation due to the sudden increasing price of vegetable oil. As a result,
substantial number of biodiesel plants were left idle, some even sold as scrap metal. Such scenario could be overcome by utilizing a cheaper and sustainable
feedstock. Palm fatty acid distillate (PFAD) could be the answer to a commercially viable biodiesel production. Hence, production of fatty acid ester (FAE) from
PFAD containing high free fatty acids (FFA) was investigated in this work. Batch esterifications of PFAD were carried out to study the influence of reaction
temperatures of 70–100 °C, molar ratios of sustainable acyl acceptors to PFAD of 0.4:1–12:1, quantity of catalysts of 0–5.50% (wt of catalyst/wt of PFAD) and
reaction times of 15–240 min. Optimum conditions, reaction kinetics and mass transfer activities will be investigated. It is expected that the amount of FFA to
reduced from more than 90% to below 5% at the end of the esterification process. FAE will be further purified with alkaline medium and the final biodiesel product
will be tested in accordance to quality standard ASTM D6751-02.

Combustion Characteristics of Refuse Derived Fuel (RDF) in a Fluidized Bed Combustor

JOHARI*, R. MAT, H. ALIAS, H. HASHIM, M.H. HASSIM, Z.Y. ZAKARIA & M. ROZAINEE

ABSTRACT

The combustion characteristics of refuse derived fuel (RDF) in a fluidized bed have been studied. The gross heating value (GHV) of the RDF was 14.43 MJ/kg with moisture content of 25% by weight. Parameters of interest for sustainable bed combustion were the fluidization number and primary air factor. The study was performed in a rectangular fluidized bed combustor with dimensions of 0.3 m in width, 0.7 m in length and 2 m in height. Sand with mean particle size of 0.34 mm was used as a fluidization medium. The sand bed height was at 0.3 m above the standpipes air distributor. The range of fluidization number under investigation was 5–7 Umf in which 5 Umf was found to be the optimum. The study was continued for the determination of the optimum primary air factor with the selected range of primary air factors being 0.6, 0.8, 1.0 and 1.2 in experiments conducted at 5 Umf. The final results showed that the optimum primary air factor was at 0.8. An energy balance was also performed to determine the thermal efficiency of the combustion. It was concluded that the thermal efficiency depended on the bed temperature and the primary air factor being used.

Keywords: Air factor; fluidized bed combustor; fluidization number; operating parameter; refuse derived fuel (RDF); thermal efficiency

What is H-index

Posted on January 26, 2014 ·

Previously researchers are rank based on how many impact factor journals they have. However, recently, a more superior measure was used which is the h-index.

So, what is h-index?

H-index is an index that attempts to measure both the productivity and citation body of work published in the scientific and akateemisia.Indeksi based on the number most cited scientific articles and the number of citations received in other publications. The index can be applied to the productivity and effectiveness of the academic journal and a group of scientists, such as department or university or country. The index was proposed in 2005 by Jorge E. Hirsch, a physicist at UCSD, as a means to determine the relative quality of a theoretical physicist “,  and is sometimes called the Hirsch Hirsch index or number.

The index is based on the distribution of citations received by a given researcher’s publications. Hirsch writes:

A scientist has index h if h of his/her Np papers have at least h citations each, and the other (Np − h) papers have no more than h citations each.

For more information about h-index, refer here.

Thermodynamic

Posted on December 30, 2013 ·
Thermodynamics is the physics associated with the relationship between heat and other features (such as pressure, density, temperature, etc.) of a substance.Especially focusing on how thermodynamic heat transfer associated with different energy changes in physical systems undergo thermodynamic processes. This process usually results in the work system and governed by the laws of thermodynamics.

Thermodynamic also study the relationship between energy and entropy, which is related to the heat and work. It is a set of theories related to the macroscopic properties which we can measure (eg, temperature, volume and pressure) for energy and the ability to provide employment. A thermodynamic system is defined as the total mass of waste and identity. Everything outside the system which is separated from the environment and environmental systems at the borders. Some applications of thermodynamics including design:

1)  AC and fridge
2)  turbo compressor motor
3)  steam turbine power plant
4)  engines used in airplanes

In the beginning of thermodynamics, which is used to warm up the engine, is working on thermal properties of materials “such as steam, in order to improve efficiency and engine power. Thermodynamics then continued to study energy transfer in chemical processes, such as surveys, published in 1840, of thermal chemical reaction by Germain Hess, who was initially unclear handle the relationship between energy exchange with the heat and work.
