Thus, the use of a reactive recycle stream is another innovation in this technology. The hydrogen required for the HDO will be generated in the catalytic section by the water-gas shift reaction employing recycled CO produced from the pyrolysis reaction itself. The approach is to carry out catalytic hydrodeoxygenation (HDO) and upgrading together with pyrolysis in a single fluidized bed reactor with a unique two-level design that permits the physical separation of the two processes. In addition to ChemDraw Ultra itself, the ChemBioDraw Ultra 11.0 software suite includes:The objective of the proposed research is the demonstration and development of a novel biomass pyrolysis technology for the production of a stable bio-oil. ChemBioDraw is designed to increase productivity in a variety of scientific environments.

Fast pyrolysis integrated with hydrotreating is one of the simplest, most cost-effective and most efficient processes to convert lignocellulosic biomass to liquid hydrocarbon fuels for transportation, which has attracted significant attention in recent decades. Lignocellulosic biomass, which is the most abundant and inexpensive renewable feedstock on the planet, has a great potential for sustainable production of fuels, chemicals, and carbon-based materials. Commercial software packages, such as Alchemy 2000 27, ChemDraw 28, and.There is considerable world-wide interest in discovering renewable sources of energy that can substitute for fossil fuels. The stoichiometry of the element symbols is indicated at the lower right-.

В«В lessThis University of Massachusetts, Amherst project, 'Fast Pyrolysis Oil Stabilization: An Integrated Catalytic and Membrane Approach for Improved Bio-oils' started on 1st February 2009 and finished on August 31st 2011. This review provides a survey of the relevant literatures of recent 10 years about the advances in the understanding of the HDO chemistry of bio-oils and their model compounds mainly on noble metal catalysts. The reaction mechanisms of HDO of model compounds on noble metal catalysts as well as their efficacy for hydrotreating or stabilization of bio-oil have been recently reported. A wide range of catalysts have been studied, including conventional Mo-based sulfide catalysts and noble metal catalysts, with the latter being the primary focus of the recent research because of their excellent catalytic performances and no requirement of environmentally unfriendly sulfur. Significant research has been conducted to address the practical issues and provide the fundamental understanding of the hydrotreating/hydrodeoxygenation (HDO) of bio-oils and their oxygen-containing model compounds, including phenolics, furans, and carboxylic acids. Specifically, development of active, moreВ В» selective, and stable hydrotreating catalysts is the bottleneck due to the poor quality of pyrolysis bio-oil feedstock (high oxygen content, molecular complexity, coking propensity, and corrosiveness).

The results clearly showed that the cake formation mechanism of fouling is predominant in this process. The results demonstrated the removal of the major quantity of char particles with a significant reduction in overall ash content of the bio-oil. Tubular ceramic membranes of nominal moreВ В» pore sizes 0.5 and 0.8m were employed to carry out the microfiltration, which was conducted in the cross-flow mode at temperatures ranging from 38 to 45 C and at three different trans-membrane pressures varying from 1 to 3 bars. This study focused on the application of a liquid-phase microfiltration process to remove char particles from bio-oil down to slightly sub-micron levels. Currently there is no well-established technology to remove char particles less than 10 micron in size.

However, all of the membranes were irreversibly damaged when experiments were conducted with the model AFBO due to the presence of guaiacol in the feed solution. Retention factors above 90% for glucose and below 0% for acetic acid were observed at feed pressures near 40 bar for single and binary solutions, so that their separation in the model AFBO was expected to be feasible. Experiments were carried out with a single solute solutions of acetic acid and glucose, binary solute solutions containing both acetic acid and glucose, and a model aqueous fraction of bio-oil (AFBO).

Acetic acid is very resilient to hydrogenation and we could only achieve about 16% conversion for acetic acid. Task 3.0 Acid Removal by Catalytic Processing It was found that the TAN reduction in bio-oil was very difficult using low temperature hydrogenation in flow and batch reactors. NF membranes showed retention factors of glucose greater than 80% and of acetic acid less than 15% when operated at transmembrane pressures near 60 bar.

The pH of the bio-oil increased from 2.43 to 3.7. Task 4.0 Acid Removal using Ion Exchange Resins DOWEX M43 resin was used to carry out the neutralization of bio-oil using a packed bed column. Hydrogenation experiments with whole bio-oil were difficult to perform because of difficulty to pumping the high viscosity oil and reactor clogging. Again, negligible acetic acid conversion was obtained in low temperature hydrogenation. Hydrogenation of the whole bio-oil was carried out at 125вЊ, 1450 psi over Ru/C catalyst in a flow reactor. The bimetallic catalyst PtRe/ceria-zirconia was found to be best catalyst because its ability to convert the acid functionality with low conversion to gas phase carbon.

The capital cost for these improvements would be less than 2% of the total plant capital cost. Microfiltration of the bio-oil was also researched to remove char particulate from the bio-oil. Cyclones were placed in the vapor stream to reduce char particulate carryover. Changes were made in the bio-oil recovery methodology and a reactor sweep gas used to reduce vapor residence time.
