3 Typical project features System perspective Proposal of innovative design solutions Integration of different processes/productive chains/plants High level of interdisciplinarity Tools for solution analysis Numerical models with mass and energy balances Integration strategies for material and thermal streams Optimization techniques Evaluation of solution: metrics of performance Raw resource saving Primary energy usage Yield Economic convenience (production costs, IRR)

4 f3 - The Swedish Knowledge Centre for Renewable Transportation Fuels f3 purpose: Contribute with scientifically founded decision support for policy makers, government, industry and other organizations, concerning future production of renewable fuels and related system aspects by Complementing other R&D Develop communication internally and externally Make syntheses and analyses of current R&D Develop new knowledge through collaboration between research groups and disciplines Contribute to the dissemination of knowledge and thereby increase and broaden the competence level

5 f3 - The Swedish Knowledge Centre for Renewable Transportation Fuels Bio4Energy is a partner in f3 Several project of different types Complementary system analysis studies (LCA / land use) Comparison of production routes Optimal localization in national perspective Mission: Governamental report on motor fuel production and sustainability

6 f3 industrial partners Perstorp (biodiesel) Sekab (ethanol) Göteborg Energi, E-On (gasification for SNG) Lantmaennen (agricultural feedstock) Volvo, Scania, Preem (motor fuel users)

7 Black liquor fractionation Industrial partner: Smurfit Kappa Separation of hemicellulose and lignin by precipitation Butanol production via hydrolization of hemicellulose Development of models for calculating the yield Process integration and economic evaluation of the production route

8 C-preserving biomass fermentation Industrial partner: Sekab Comparison of two production routes for butanol production Tradtional: fermentation of wheat straw Catalytic: conversion from succinic acid (requires CO2) Development of models for calculation of yields and production costs

9 Co-gasification of BL/pyrolysis oil Industrial partner: Rottneros Vallvik Purpose Increase methanol production from the gasification of black liquor only Pyrolysis oil has a higher LHV, but gasification requires high T -> mixing with black liquor should reduce the gasification temperature Different blends are simulated Economic analysis where the stand-alone plants for pyrolysis oil production evaluation of methanol production cost

10 Utilization of forest resources Industrial partners: SveaSkog, LKAB pre-study sponsored by Vinnova SWAT analysis for high utilization and productivity Sector economic analysis to understand the behavior of forest owners how they could react to new policy instruments (incentives, taxes) or market variations Bottom-up approach to build the supply curve (harvested quantity cost)

11 Social benefits from pilot plants Industrial partners: Chemrec, Sekab pre-study Purposes increase the knowledge about social benefits of biorefinery pilot and demonstration plants in the transition towards a bio-based economy identify the policy tools that could strengthen these benefits Methods Investigate the networks of actors around important biorefineryrelated plants in Sweden (4 test-cases), and their role in knowledge generation enabling technology up-scaling and diffusion. potential spillover effects on other sectors, including new ideas for basic research (i.e., knowledge spillovers).

12 Pulp and paper mill thermal streams Industrial partner: Billerud Karlsborg Integration of thermal streams within the plant Heat integration in the multi-effect evaporator Minimization of the external heat required by the process streams Redesign of CHP system Improvment of Rankine cycle design parameters Redefinition of the steam balance in the plant Analysis of different scenarios

13 Supply chain to pulp and paper mills Industrial partner: Billerud Karlsborg Design of an integrated site Sawmills, log chopping, pellet plant, BL and bark mix boilers or gasifiers Integration of material streams for a fixed production of the pulp and paper mill Design of an integrated CHP system to provide heat and power requirements to the plants Analysis of several scenarios according to different aspects: resources, energy, economy

14 Methanol synthesis Industrial partner: Billerud Karlsborg Two alternatives to produce syngas for methanol synthesis Bark boiler is replaced by a woody biomass gasifier The BL boiler is replaced as well by a gasifier (blend) Capacities are adjusted to keep the same steam balance in the pulp and paper mill Economic analysis (methanol production cost) to see if the integrated solution is better than the case of stand-alone plants

15 Ammonia synthesis Industrial partner: Billerud Karlsborg Two alternatives to produce syngas for ammonia synthesis Bark boiler is replaced by a woody biomass gasifier The BL boiler is replaced as well by a gasifier (blend) Capacities are adjusted to keep the same steam balance in the pulp and paper mill Economic analysis (IRR) to see if the integrated solution is better than the case of stand-alone plants
