Integrated Multiscale Chemical Product Design using Property Clustering and Decomposition Techniques in a Reverse Problem Formulation
(2011-11-30)
In recent years, chemical engineers in the Process Systems Engineering (PSE) community have increasingly been using their skill set to solve problems in areas beyond the chemical manufacturing processes, focusing instead ...
Hydrogen Production in Supercritical Water
(2011-04-15)
Hydrogen has been considered as an environmentally friendly energy carrier for the future. It is not found freely in nature but must be obtained by processing hydrogen containing compounds. Current industrial-scale ...
Modeling and Optimization of Novel Fuel Production Strategies
(2011-10-18)
Environmental problems such as global warming and fossil fuel shortage are some of the biggest challenges that human beings are facing nowadays. Alternative fuels are the potential answer to many future energy needs and ...
Incorporating Green Chemistry Principles in Heterogeneous Catalysis Operations
(2011-08-25)
Many commercial processes for the production of chemicals involve harsh organic solvents as well as numerous by-products that are detrimental to the environment. For many years it was common practice to implement a process ...
Bioconversion of Pulp and Paper Mills Sludge and Prehydrolysate Stream into Ethanol and Cellulase Enzyme
(2011-05-17)
In the first part of this dissertation, two different types of paper mill sludges, primary sludge and recycle sludge, were evaluated as a feedstock for bioconversion to ethanol. The sludges were first subjected to enzymatic ...
