Automated Upgrading of Component-Based Applications
Not only does our toolset reduce the burden of manual upgrades, but it will influence component designers as well. Without fear that they break the existing applications, designers will be bolder in the kind of changes they can make to their designs. Given this new found freedom, designers will …

Catalytic Upgrading of Lignin From Biomass
… lignocellulose. Effective and economical lignin upgrading techniques have remained elusive, largely due to the complex structure and reactivity of lignin during processing. Broadly, my graduate work has focused on designing experiments to gain fundamental understanding while working with complex, …

Upgrading biomass by hydrothermal and chemical conditioning
There are two widely known thermal pretreatment technologies, known as hydrothermal carbonization and dry torrefaction. In dry torrefaction, also known as torrefaction or mild pyrolysis, dry solid biomass is treated in an inert gas environment in a temperature range of 200-300oC for more than one …

Catalytic Light Hydrocarbon Upgrading under Methane Environment
The catalytic light hydrocarbon upgrading is explored under methane environment over metal modified zeolites. This novel process not only replaces naturally unavailable hydrogen with methane in the upgrading process, but also converts methane into value added products such as fuels and aromatic …

Chemistry of alkylaromatics in crude oil upgrading
… work simplifies the study of supercritical water upgrading of crude oil to a hexylbenzene pyrolysis system. The pyrolysis of hexylbenzene at process conditions of 450°C and 75 creates several hundred products resolved by GCxGC, and the analysis is intractable if one considers only the experimental …

Ecological Studies on the Microbial Upgrading of Straw
… the implications of the results for the proposed upgrading technique were considered. The utilisation of lignin and cellulose by a number of isolates of C cinereus were compared under conditions of varying pH and temperature and capabilities were found to differ with the isolates. The feasibility …

Novel catalytic methods for the upgrading of coal liquids
… are designed as hydrocracking catalysts for the upgrading of liquids obtained by the processing of coal. Contact with both coal derived liquids and heavy petroleum resids has demonstrated that these catalysts are superior to established proprietary catalysts in terms of both initial activity and …
