Research Project: LIFE CYCLE GHG EMISSIONS OF PYROLYSIS/BIO-OIL AND BIOCHAR PRODUCTS

Location: Sustainable Biofuels and Co-Products

2011 Annual Report


1a.Objectives (from AD-416)
To evaluate the greenhouse gas (GHG) intensity of fuel oil (bio-oil) and biochar co-products derived from agricultural residues to test its suitability as a substitute for fuel oil through life cycle analysis. Identify and quantify all process inputs (e.g., N, P, K) to replace residue removed from land and collection activities.


1b.Approach (from AD-416)
Construct a base-case scenario that evaluates the full life cycle greenhouse gas emissions converting agricultural feedstock to pyrolysis oil and biochar, construct cost analysis to estimate the cost of mitigating GHG and compare the pyrolysis oil/biochar scenario with the life cycle emissions of fossil fuel. Track material and energy inputs and GHG emissions to air from the feedstock production, collection, transport, fuel conversion, fuel transport and distribution, and use in a hypothetical 100% ethanol (E100) vehicle.


3.Progress Report

Model construction is underway and preliminary results to be presented at the 2011 AIChE Annual Conference in October. Progress was monitored by e-mails and site visits.
