Non Technical Summary
The explosive growth of biofuels in recent years has shown that there is great potential for biomass to be a raw material for the production of transportation fuels. Possibly the most economical means to produce biofuels is by the liquification of biomass (fast pyrolysis) and subsequent upgrading. This method is also potentially the most sustainable, provided the feedstock is produced sustainably. Fortunately there are large quantities of waste biomass materials available. What we need is new technology to cost-effectively upgrade the pyrolysis oil to high value fuels such as diesel. Middle distillate fuels such as diesel and aviation fuel are necessary to meet the needs of large-scale transportation, heavy equipment such as shipping and aviation. Thus, diesel fuel will be in demand for the foreseeable future. What is unclear is how much diesel fuel can be produced from renewable sources. Diesel fuel is comprised of molecules that have more carbon atoms than gasoline or ethanol. Therefore diesel is more difficult to produce from the monomers of the molecules typically found in biomass - proteins, cellulosics, starches, carbohydrates, etc., which are made of C3 to C6 segments. Thus, converting general biomass to diesel fuel is the most technologically challenging synthesis route, but also the most potentially profitable because diesel is more valuable than other fuels. Any rational approach to converting biomass waste to fuels involves minimizing the distance that low-density biomass materials must be transported to the conversion site. In this project we will address the need to minimize the travel distances by developing a small-scale process that can be located anywhere there is waste biomass. It will not rely on existing petrochemical refining infrastructure (aside from existing fuel terminals where the biofuel enters the distribution network). TDA proposes to develop a biomass-to-diesel process that combines the fast pyrolysis of any biomass or other waste source of oxygenated hydrocarbons followed by upgrading of the bio-oil intermediate to middle distillate equivalents. The key technological innovations that will make this process attractive are: (#1) using essentially 100% of almost any type of biomass or waste product; (#2) developing novel chemical conversion routes that allow for much lower temperatures and pressures to be used, thus reducing energy input needs, improving the safety of the process, and simplifying it; (#3) combining novel chemical conversion pathways that will allow us to both upgrade (increase the molecular weight) the biomass-derived oil and deoxygenate it; (#4) producing a fuel product that is fungible with ULSD (ultra low sulfur diesel).

Goals / Objectives
This project will develop and evaluate a new process for converting biomass waste into green diesel. The biomass waste will first be converted into pyrolysis oil and then catalytically upgraded to diesel. The process uses a new approach to upgrading pyrolysis bio oil and does not produce sulfur-containing or other environmentally harmful by-products.
Project Methods
The project will develop, test and evaluate a new process for producing diesel from biomass pyrolysis oil. The bio oil (pyrolysis oil) can be produced from any biomass source including but not limited to forest wood biomass, grassland biomass, organic non-recyclable components of municipal solid waste, and cellulosic waste material. We will produce new catalysts and test them in a custom-built automated reactor apparatus. Samples of fast pyrolysis oil and mixtures of model compounds will be processed in the reactor over the catalyst. The liquid fuel products will be analyzed for composition, molecular weight range and oxygen content. We will also perform a preliminary engineering and economic analysis of the overall biomass waste-to-diesel fuel production process.

Impacts
What was accomplished under these goals? The Phase I work plan was designed to develop and prove the critical steps of the process. The technical questions that were answered in Phase I are; (1) can bio oil be upgraded to middle distillates with pre-treatment reactions prior to final deoxygenation?; (2) can the use of ahydrogenation avoid coking and catalyst de-activation in the complete HDO step; (3) can a sequential process (upgrading –hydrogenation- HDO) be accomplished at moderate temperatures and pressures and produce diesel fuel? To answer these technical questions we originally established the following four technical objectives for Phase I: Task 1. Develop and evaluate aprocess to upgrade the bio-oil intermediate. Task 2. Develop and evaluate a low temperaturehydrogenation and mild HDO pre-treatment to convert highly reactive compounds into intermediates prior to sulfur-free HDO. Task 3. Develop a sulfur-free catalyzed final HDO process step toconvert the upgraded intermediate into diesel fuel. Task 4. Perform an engineering and economic analysis of the overall biomass waste-to-diesel fuel production process. All of these objectives were successfully accomplished,
