ProQuest (http://www.proquest.com/) serves as a clearinghouse for dissertations produced by graduate students from all over the U.S. Most of the ProQuest dissertations must be purchased. However, some of them are available at no charge.
Use the link below to search and retrieve all open access dissertations:

For example, searching the ProQuest open access database for hydrocarbon results in several hits, among which is …

Recycling Carbon Dioxide into Sustainable Hydrocarbon Fuels: Electrolysis of Carbon Dioxide and Water
by Graves, Christopher Ronald, Ph.D. Columbia University. 2010: 282 pages.
The purpose of this work was to develop critical components of a system that recycles CO2 into liquid hydrocarbon fuels. The concept is examined at several scales, beginning with a broad scope analysis of large-scale sustainable energy systems and ultimately studying electrolysis of CO2 and H2O in high temperature solid oxide cells as the heart of the energy conversion, in the form of three experimental studies. The contributions of these studies include discoveries about electrochemistry and materials that could significantly improve the overall energy use and economics of the CO2-to-fuels system.

TIP: Remember that there are lots more dissertations that are NOT open access. If you don’t find what you’re looking for in the open access pool, try searching for the dissertations in the restricted pool.
Searching ProQuest open access for desulfurization, for example, will result in 0 hits. That just means there are no dissertations listed in the ProQuest open access database on the topic of desulfurization. Searching the complete ProQuest database would yield much different results.
