My Google Scholar Site
Posted on December 21, 2014 ·
Google Scholar is a freely accessible web search engine that indexes the full text of scholarly literature across an array of publishing formats and disciplines. Google Scholar index includes most peer-reviewed online journals of Europe and America’s largest scholarly publishers,plus scholarly books and other non-peer reviewed journals.
Presently, it is common for researchers to have their own Google Scholar page. It will show the list of publications as well as the number of citations. It is indeed easier for researcher like me to keep track on all my publications which include journals, books, book chapters and others as they are properly organized in Google Scholar Page. It is also easier for us to check or refer to other researchers Google Scholar Page.

Abstract
Thermodynamic properties of ethanol-glycerol steam and dry reforming have been studied with the method of Gibbs free energy minimization for hydrogen production. Equilibrium compositions were determined as a function of H2O/ethanol-glycerol molar ratios (WEG)(1:6-6:1) and CO2/ethanol-glycerol molar ratios (CEG)(1:6-6:1) where ethanol-glycerol is 1:1; reforming temperatures (573-1273 K) at different pressures (1-20 bar). Optimum conditions for hydrogen production are different for both steam and dry glycerol reforming. The optimum hydrogen formation for glycerol dry reforming are temperatures 1073-1273 K and CEG of 6:1 at 1 bar pressure, whereas for glycerol steam reforming, the optimum temperature is above 1073 K and WEG ratio 6:1 and 1 bar. Higher pressure and higher WEG/CEG ratio do not encourage hydrogen formation. Under identified optimum conditions, carbon formation can be thermodynamically inhibited.
Keywords: ethanol-glycerol mixture, dry reforming, steam reforming, hydrogen production

My PSM Students for 2014
Posted on December 18, 2014 ·
Since I could not secure any postgraduate students yet for 2014, I have decided to take more PSM students.
In total, I am in charge of 9 PSM students. This looks quite a lot, but I am trying my best to manage them.
7 of them are working on research related to biodiesel whereas another 2 are working on thermodynamic modelling.

Introduction to Matlab for Engineering Students
Posted on December 14, 2014 ·
Matlab is a very important and powerful software. It is very useful for various application such as thermodynamic modelling, solving simultaneous equations, genetic algorithm, optimization and so much more. To study Matlab, several books are available. If you are interested, you can get the book written by David Houcque from Northwestern University. Following is a snapshot from the book:

1.1 Introduction

The tutorials are independent of the rest of the document. The primarily objective is to help you learn quickly the fi rst steps. The emphasis here is \learning by doing”. Therefore, the best way to learn is by trying it yourself. Working through the examples will give you a feel for the way that MATLAB operates. In this introduction we will describe how MATLABhandles simple numerical expressions and mathematical formulas. The name MATLAB stands for MATrix LABoratory. MATLAB was written originally to provide easy access to matrix software developed by the LINPACK (linear system package) and EISPACK (Eigen system package) projects.
.
MATLAB [1] is a high-performance language for technical computing. It integrates computation, visualization, and programming environment. Furthermore, MATLAB is a modern programming language environment: it has sophisticated data structures, contains built-in editing and debugging tools, and supports
object-oriented programming. These factors make MATLAB an excellent tool for teaching and research.

A Survival Guide to Chemical Engineering

This is a very useful article written by Dr. Lisa G. Bullard from the Department of Chemical and Biomolecular Engineering, North Carolina State University. It is very good for new and existing chemical engineering student to read this paper.

As you prepare to take your first chemical engineering course, you may be feeling a bit smug, or perhaps a bit nervous, or both. You managed to navigate your one-person kayak through the relatively smooth waters of the freshman year, easily maneuvering around the rocks of calculus, chemistry, and physics by spending about 30–45 minutes (usually 30) on any given homework assignment and studying the night before a test, usually for anhour and a half at the most. The terrain was familiar based on your strong high school preparation. Group work was not necessary (hence your one-person kayak); you mayhave noticed your fellow kayakers paddling along, some falling by the wayside, but most keeping pace with the group.
.
Now you and some others have made your way to what looks to be a large, remote island. As you climb out and gaze at the island, you see in the distance that there are spectacular, steep cliffs. Some have beautiful waterfalls cascading down. You can see beautiful flowers and exotic plants before you. All of a sudden some natives emerge from the forest to greet you and your fellow travelers.They look a little strange and they are speaking a language that you don’t understand. They hold out some sort of tools in an effort to be friendly (you hope), but you have no idea what they are or how to use them. You realize that you’ve developed strong paddling skills in order to get here, but you have no idea what lies ahead of you and how to reach those spectacular cliffs.
.
Welcome to Chemical Engineering.
.
Taking the first course in your major—any major—is an exciting but scary step into the unknown. There’s the excitement of feeling like you’re FINALLY getting into your chosen field, accompanied by the nagging feeling that you’re not sure what it really is or what you’ll end up doing with it. After teaching the first course in Chemical Engineering—CHE 205—several times, I’ve observed that the course is a big shock for many students. They spend several weeks or perhaps the whole semester discovering ways in which CHE 205 is different from courses they’ve taken before, and trying to figure out how to be successful. Some students quickly get “the lay of the land” and adapt their study habits to achieve success. Other students fight it kicking and screaming all semester, and either give up or barely limp
through, feeling battered and betrayed at the end of the semester.
.
In an effort to equip and inform you from Day 1, I asked some current and former undergraduate and graduate students to share advice and observations that might help you avoid the mistakes they made when they took the course. I hope that you’ll take their advice to heart, since they have successfully scaled the high cliffs and stand looking back on the journey with valuable perspective on the potential pitfalls along the way. Comments in italics come directly from students—they say it best.

Aspen Plus Tutorial Book
Posted on December 10, 2014 ·
Aspen Plus is another superior software for advance chemical engineering calculation. To those of you who are new to Aspen Plus, read this simple tutorial.
.
Introduction:
.
In industry complicated problems are often not solved by hand for two reasons: human error and time constraints. There are many different simulation programs used in industry depending on the field, application, and desired simulation products (entire process unit, one piece of equipment, etc.). When used to its full capabilities, Aspen can be a very powerful tool for a Chemical Engineer in a variety of fields including oil and gas production, refining, chemical processing, environmental studies, and power generation to name a few.
.
Over the course of these tutorials, you will be introduced to some of the basic features of Aspen as we build a simulation of an acetone/water extraction-distillation process. This problem is based very loosely on Example Problem 4.4-2 in Elementary Principles of Chemical Process by Felder and Rousseau. Because we will build on our existing simulation with each tutorial, it is highly recommended that you save your work every week so you do not have to start from scratch each time. The homework problems will emphasize one particular feature of Aspen that is covered in the tutorial for that week.
