Abstract

Pyrolysis has the potential to create a biocrude oil from biomass sources that can be used as fuel or as feedstock for subsequent upgrading to hydrocarbon fuels or other chemicals. The product distribution/composition, however, is linked to the biomass source. This work investigates the products formed from pyrolysis of woody biomass with a previously developed chemical kinetics model. Different woody feedstocks reported in prior literature are placed on a common basis (moisture, ash, fixed carbon free) and normalized by initial elemental composition through ultimate analysis. Observed product distributions over the full devolatilization range are explored, reconstructed by the model, and verified with independent experimental data collected with a microwave-assisted pyrolysis system. These trends include production of permanent gas (CO, CO₂), char, and condensable (oil, water) species. Elementary compositions of these streams are also investigated. As a result, close agreement between literature data, model predictions, and independent experimental data indicate that the proposed model/method is able to predict the ideal distribution from fast pyrolysis given reaction temperature, residence time, and feedstock composition.

Ablative fast pyrolysis: Converting wood, agricultural wastes and crops into energy and chemicals

Conference Johnson, D A ; Maclean, D ; Chum, H L ; ...

Each year more than 170 million tonnes (190 million tons) of yard waste, pallets, forest and agricultural residues are discarded that could become feedstocks for saleable products. The United Stated could potentially grow more than 450 million tonnes (500 million tons) per year of energy crops as dedicated feedstocks in an economically and environmentally sustainable way. About 85% of this lignocellulosic material can be converted into a biocrude oil and charcoal via fast pyrolysis. An engineering scale pyrolysis system has been designed and is being built according to the NREL ablative vortex fast pyrolysis concept in Kansas City. The systemmore »« less
Influence of the Feedstock on Catalytic Fast Pyrolysis with a Solid Acid Catalyst

Journal Article Wang, Kaige ; Mante, Ofei D. ; Peters, Jonathan E. ; ... - Energy Technology

Abstract At RTI, we are developing a catalytic fast pyrolysis process with a new solid acid catalyst, the performance of which has been evaluated in a pilot‐scale reactor using loblolly pine. More robust technology development requires a deeper understanding of the influence of the feedstock properties of process performance defined by the organic liquid yield and composition. Seven types of woody and herbaceous biomass were tested in a 2.54 cm diameter fluidized‐bed reactor. This study shows that the product distribution and biocrude composition vary widely with different feedstocks. The yield of organic biocrude is in the range of 14.0–20.8 wt % for themore »« less

Comparing Life-Cycle Emissions of Biofuels for Marine Applications: Hydrothermal Liquefaction of Wet Wastes, Pyrolysis of Wood, Fischer–Tropsch Synthesis of Landfill Gas, and Solvolysis of Wood

Journal Article Masum, Farhad H. ; Zaimes, George G. ; Tan, Eric C. D. ; ... - Environmental Science and Technology

Recent restrictions on marine fuel sulfur content and a heightened regulatory focus on maritime decarbonization are driving the deployment of low-carbon and low-sulfur alternative fuels for maritime transport. In this study, we quantified the life-cycle greenhouse gas and sulfur oxide emissions of several novel marine biofuel candidates and benchmarked the results against the emissions reduction targets set by the International Maritime Organization. A total of 11 biofuel pathways via four conversion processes are considered, including (1) biocrudes derived from hydrothermal liquefaction of wastewater sludge and manure, (2) bio-oils from catalytic fast pyrolysis of woody biomass, (3) diesel via Fischer–Tropsch synthesis of landfill gas, and (4) lignin ethanol oil from reductive catalytic fractionation of poplar. Our analysis reveals that marine biofuels’ life-cycle greenhouse gas emissions range from –60 to 56 gCO₂e MJ^–1, representing a 41–163% reduction compared with conventional low-sulfur fuel oil, thus demonstrating a considerable potential for decarbonizing the maritime sector. Due to the net-negative carbon emissions from their life cycles, all waste-based pathways showed over 100% greenhouse gas reduction potential with respect to low-sulfur fuel oil. However, while most biofuel feedstocks have a naturally occurring low-sulfur content, the waste feedstocks considered here have higher sulfur content, requiring hydrotreating prior to use as a marine fuel. Combining the break-even price estimates from a published techno-economic analysis, which was performed concurrently with this study, the marginal greenhouse gas abatement cost was estimated to range from –more »« less

Pyrolysis of forest residues: An approach to techno-economics for bio-fuel production

Journal Article Carrasco, Jose L. ; Gunukula, Sampath ; Boateng, Akwasi A. ; ... - Fuel

Here, the techno-economics for producing liquid fuels from Maine forest residues were determined from a combination of: (1) laboratory experiments at USDA-ARS’s Eastern Regional Research Center using hog fuel (a secondary woody residue produced from mill byproducts such as sawdust, bark and shavings) as a feedstock for pyrolysis to establish product yields and composition, and (2) Aspen Plus® process simulation for a feed rate of 2000 dry metric tons per day to estimate energy requirements and equipment sizes. The simulated plant includes feedstock sizing and drying, pyrolysis, hydrogen production and hydrotreatment of pyrolysis oils. The biomass is converted into bio-oilmore »« less

A simplified integrated framework for predicting the economic impacts of feedstock variations in a catalytic fast pyrolysis conversion process

Journal Article Wiatrowski, Matthew R. ; Dutta, Abhijit ; Pecha, M. Brennan ; ... - Biofuels, Bioproducts & Biorefining

Abstract Feedstock attributes of lignocellulosic biomass, such as particle size, compositional makeup, and moisture content, can vary substantially even within pre‐processed materials and have a significant effect on conversion in fast pyrolysis‐based processes. However, the economic impacts of these attributes are not well understood. To address this, biomass deconstruction phenomena captured with a versatile particle‐scale simulation were linked to techno‐economic impacts via reduced‐order models. Parametric analysis of the particle‐scale model, which was validated using literature data, was used in combination with multiple linear regression models to develop correlations between feedstock attributes and yields of pyrolysis oil, gas, and char.
