Message to my blog visitors "Doctors & Professors"

Dear All,

This special message to my visitors: Doctors and Professors of Chemistry and Chemical Engineering discipline from USA, Europe, Asia and Australia, my greetings to you.

 As one of my targets is to complete higher studies as possible, after I graduated till now I am seeking for either research assistantship position or full scholarship for Master or integrated MSc to PhD degree in one of the following fields: Thermo-chemical conversion of biomass and organic wastes using gasification and pyrolysis technologies, membrane technology for purification and separation of gases, and building of fuel cells. Synthetics inorganics for environment and energy applications, synthesis and improvement of catalysis for biofuels and sustainable technologies, Metal-Organic Frameworks for storing of hydrogen and methane.

I obtained BSc (Hons) Class One in Industrial Chemistry with CGPA 3.74/4.00, I have good skills in how to search data and information, e-books, magazines and scientific papers on internet. You can visit my profile on linkedin to know more about me.

If you have a vacant position to me, feel free to contact me.

Thanks in advance,

Yours Sincerely,

Ahmed Abdellatif Hassan

The Chemistry and Technology of Petroleum, Fourth Edition, By J. G. Speight

CRC Press; 4 edition (October 31, 2006) | ISBN: 0849390672| Pages: 984 | RAR | 7.38 MB

Refineries must not only adapt to evolving environmental regulations for cleaner product specifications and processing, but also find ways to meet the increasing demand for petroleum products,particularly for liquid fuels and petrochemical feedstocks. The Chemistry and Technology of Petroleum, Fourth Edition offers a 21st century perspective on the development of petroleum refining technologies.

Like its bestselling predecessors, this volume traces the science of petroleum from its subterranean formation to the physicochemical properties and the production of numerous products and petrochemical intermediates. Presenting nearly 50 percent new material, this edition emphasizes novel refining approaches that optimize efficiency and throughput. It includes new chapters on heavy oil and tar sand bitumen recovery, deasphalting and dewaxing processes, and environmental aspects of refining, including refinery wastes, regulations, and analysis. The text also features revised and expanded coverage of instability and incompatibility, refinery distillation, thermal cracking, hydrotreating and desulfurization, hydrocracking, and hydrogen production.

A unique, well-documented, and forward-thinking work, this book continues to present the most complete coverage of petroleum science, technology, and refining available. The Chemistry and Technology of Petroleum, Fourth Edition provides an ideal platform for scientists, engineers, and other professionals to achieve cleaner and more efficient petroleum processing methods.
