ABSTRACT
Speaker’s Bio
Dr. Ruh Ullah holds a PhD degree in
Chemical Engineering. He has been
working as a post-doctoral research
fellow in the Department of Chemical
Engineering, Qatar University with
Professor Mert Atilhan since October
2013. He received his PhD degree from
Curtin University Perth, Australia in 2012.
After completion his PhD Dr. Ruh worked
in Curtin University as Research Associate
and Sessional Lecturer for one year (June
2012 June 2013). Prior to joining PhD,
and after completion of Master Degree
from Asian Institute of Technology,
Thailand, he served as Senior Lecturer
and Project Director for three years
(2006-2009) in National University of
Science and Technology (NUST), Pakistan.
Dr. Ruh has been awarded with the
FINALIST certificate from CSIRO Australia
based on his innovative research in the
field of Nanotechnology and
Environmental remediation. His research
experience lies in nanomaterial synthesize
characterization and applications for
water and air purification. He has 8
journal publications in his credit and has
attended more than 12 international
conferences as a speaker,
Worldwide emergent demand for energy has compelled the
nations to convert the naturally available resources of petroleum
into H2 using various technologies. These energy production
technologies have generated an unavoidable associated concern of
CO2 emission, which has subsequently caused various health and
environmental issues. Air pollution, particularly with access
amount of carbon dioxide has been the World’s biggest
environmental issue. Numerous techniques and materials have
been used to capture and separate the unwanted CO2 emitted at
any stage during the industrial process of energy production from
natural resources. However, selection of material for CO2 capture
at different environmental and industrial conditions is still a major
challenge for the energy production sector. Large number of
materials such as polymers, co-polymers, organic, inorganic,
metal organic composites, solids, liquid, ionic liquid and various
nano-composite structures have been investigated to separate CO2
from the useful fuel. Some of the major challenges that require
due attention at the material selection stage are; CO2 capturing
efficiency, reproducibility, selectivity, capability, stability at
various temperature and pressure conditions, multi-purpose
applicability and economic practicability of the material.
However, studies have revealed that solid sorbents are the most
suitable materials for CO2 adsorption than the commonly used
liquid amine as long as regeneration and efficiency of the material
is concerned. Polybenzimidazole (PBI) and SBA15 have been
considered as best options, since these materials have high
thermal stability, mechanically robust molecular nature and
tuneable mesoporous structure. Simulation study on precombustion CO2 has suggested that, PBI and SBA15 based
membrane are more advantageous than commonly used selexonal
techniques due to the lower cost of energy. Syngas cooling step
can be excluded since these solid sorbents can operates at high
temperature of 450 °C and pressure of 40 bars. Based on the
strong thermal and mechanical stability, suitable mesoporous
structure, better CO2 selectivity and affinity and economic
viability on large scale application of solid sorbents, we have
focused on the investigation of high pressure CO2 adsorption.
Dr. Ruh Ullah will talk about the CO2 adsorption characteristic of
few selected materials (investigated at Qatar University) at
ambient and at high pressure of 50 bars
