(7d) Kinetic of Biomass Fast Pyrolysis

My research over the last nine years has focused on the energy regarding relation between surface and interface of fluids for the purpose of enhanced oil recovery and asphaltene behavior in petroleum reservoir under different condition. My Ph.D. thesis focus on Kinetics of Biomass Fast Pyrolysis, which is funded by National Science Foundation (NSF).I designed a new microreactor micro spherical biomass particle technique for the study of kinetic of biomass fast pyrolysis which is the best method for production of biofuel with less pollution.

In the beginning, my research was about the effect of temperature and pressure on kinetic of asphaltene deposition during of capturing CO2 as the global gas environment. One of my papers was published in American Chemical Society (ACS) publication which its detail is on my C. V. Then I started my thesis on investigating the effect of temperatures, pressures and composition on CO2 solubility and miscibility by measuring interfacial tension during CO2 caption. My first paper of thesis was published in chemical engineering data journal (American Chemical Society (ACS Publication) ) on the first page of the advertising board. This paper was in the title of "Temperature and Composition Effect on CO2 Miscibility by Interfacial Tension Measurement ". I completed my second paper of my thesis in the title of " Investigating the Effects of Temperature, Pressure, and Paraffin Groups on the N2 Miscibility in Hydrocarbon Liquids using the Interfacial Tension Measurement Method" by the march of 2013 which is published in I&EC journal (American Chemical Society (ACS Publication) ).

After finalizing my master thesis, I became a member of a group that is conducting research on modifying the parachor model, neural network, molecular dynamics simulation by interfacial tension technique to measure the solubility of the global gas environment (such as CO2) at different pressure and temperatures.

My main specialties are in the investigation of kinetic, thermodynamic and heat transferring on the solubility of different materials, also relation to surface properties (such as wettability alteration and interfacial tension).

Since I am so much interested in research and development, also the today's problem with population and global warming I was searching for a project to help the environment and ultimately beneficial to humankind. I was searching the internet and interesting enough I found the project in the title of “A multi-scale environmental and kinetic study on the pyrolysis of sustainable biomass feedstock” at Tennessee Tech University. During my Ph.D. research, a novel laboratory-scale fast pyrolysis technique is demonstrated using biomass microspheres and a unique single-particle micro-reactor technology. The biomass microspheres technology provides a controlled geometry feedstock while the novel reactor enables the control of residence time factors. With this new technique, the amount and rate of hydrocarbon gas production are measured by flame ionization detector. The effects of biomass particle size on the fast pyrolysis within three different types (crystal cellulose, switchgrass, and tall fescue) is investigated to determine the char yield and reaction dynamics. The Calculated kinetic parameters were used to predict the dynamic temperature of spherical biomass.

Summary of Top Achievements:

1- New technology (microreactor microsphere) for the study of kinetic of biomass fast pyrolysis to produce biofuel.

2- Relation between temperature and pressure on CO2 –N2 injection process in petroleum reservoir by Interfacial tension properties, and one of my papers which have been accepted in Journal of Chemical & Engineering Data (has selected on advertising board on ACS Publications).

3- Investigation of CO2 injection in asphaltene deposition at reservoir condition by new visual apparatus.

4- Effect of native and non-native resin in asphaltene deposition at reservoir condition.

5- Develop one semi-empirical equation for measuring of interfacial tension of hydrocarbon components with CO2.

6- Investigation of mass transfer and molecular behavior of components in surface of CO2-N2 and paraffin component

My future research plans include completing my current research on kinetic of biomass fast pyrolysis and also using my previous experiences on Asphaltene deposition, Surface and interface properties, Molecular modeling simulation and Enhanced oil recovery methods to write a proposal to be qualified to receive a grant.

Teaching Interests:

I believe in the real and complex engineering and science environment, the principle key for solving sophisticated problems and engineering obstacles is creativity and how to learn the problem-solving process. During my first mathematics and chemical engineering design courses in university, I made a great effort to improve my creativity skills along with learning the problem-solving process. That became a fundamental motivation for me during graduate school. Therefore, as a teacher, I will strive to teach my students with these two essential factors to motivate them and provide them with extensive understanding. I believe it will encourage students learning challenging topics, guide them to recognize and completely understand the fundamental concepts in chemical engineering and build confidence in their abilities. I would like to make my students capable of analyzing and evaluating on their own to become an independent learner.

Chemical engineering is one of a fascinating major among all engineering disciplines with distinct theoretical and experimental aspects. From the theoretical point of view, strong knowledge and deep understanding of applied mathematics are ineluctable specifically at senior and graduate levels. Applied mathematics brings about great insight for the student to trust their intuition and problem-solving skills to assess and investigate widespread problems. In my Thermodynamic course, I encouraged students to focus on conceptual aspects of each problem by solving selected practical problems in class and providing alternative approaches to express different perspectives at each problem. This strategy of teaching will give rise to more motivation, satisfaction, and self-confidence.

Additionally, my experience as a teaching assistant in Thermodynamic course enabled me to realize the importance of practical and experimental aspects of chemical engineering by suggesting different methodologies for involving students in practical perspectives of materials and problems. First, I will present the theories for each section concisely and will spend more time on technical and practical examples. As an example, in Fluid mechanics course, I provided lab demonstration and placed students in groups to work with experimental setups and software to build their practical skills. Second, I will take advantage of visual demonstrations and graphs. Finally, I will involve my students in practical discussions and by offering them the opportunity to experience challenging concepts. During my teaching experience, I recognized that a proper evaluation method was to assign students homework problems which required comprehensive work throughout the semester. Homework assignments and examinations helped students demonstrate their knowledge and problem-solving skills and analyze solutions properly. In most chemical engineering courses, results can be reached by more than one method. I require my students to verify their analysis by computer simulation, as well. Moreover, individual and group assignments or final projects can help students acquire deeper and conceptual understanding. Projects should be flexible enough to serve different student’s interests and to evaluate each student’s skill and expertise. I take advantage of various types of exams and projects, such as problem-solving and take home exams. Additionally, I welcome feedback from students which allow me to evaluate my performance during a semester by conducting teacher evaluation survey in my class to assure what my students expect of me to improve my teaching skills and methods.
