Conference Presentations - 2011 AIChE Annual Meeting

The acid catalyst promotes esterification by reacting the carboxylic group of the FFA with methanol to form methylesters and water. In this reaction mixture, the sulfuric acid is more miscible in the water product phase than the methanol phase leading to a pronounced water inhibition effect that...

Production of biodiesel by esterification or transesterification of long-chain fatty acids is a well known process, but the fuel product has characteristics making it not fully compatible with petroleum diesel engines. A better option is to convert fatty acid molecules to hydrocarbons by removing...

The Hanford K Basins were used until the mid 1960s to store, under water, spent nuclear fuel from the site’s reactors before reprocessing to recover uranium and plutonium. A sludge consisting of cladding corrosion products, uranium, fission products and other debris accumulated on the floor of the...

Multivariate data analysis has recently emerged as a critical tool to gain fundamental understandings of process characteristics, and thus assisting the search for possible intervention means to improve process performance. The time dynamics of 150 process parameters acquired from 243 production...

Coke formation appears as a reason for catalyst deactivation and results in undesirable product selectivity in biomass pyrolysis. However, there is no effective way to separate coke and char in the majority of current approaches, which prevents studying coke formation and therefore the real reason...
