This paper presents the first assessment of the exergetic performance of a biorefinery process based on catalytic … hydroupgrading of bio-oil from fast pyrolysis. Lignocellulosic biomass is converted into bio-oil through fast pyrolysis, which is … then upgraded to synthetic fuels in a catalytic hydrotreating process. The biorefinery process is simulated numerically …

. Torrefaction, pelletisation and pyrolysis technologies can convert biomass at modest scales into dense energy carriers that ease …

With increasing renewable energy targets and the use of biomass for energy production, questions arise about the … production of biofuel can have on the environment, but there has been less consideration of more small scale biomass heating …

biorefineries with either integrated torrefaction or external torrefaction. The first part of the analysis showed that the biomass … torrefaction. The second part of the analysis showed that the total energy efficiency (biomass to methanol + net electricity) could … increase in energy efficiency are as follows: 1) more difficult transport, storage and handling of the biomass feedstock (wood …

recovery boiler-based pulping biorefinery concepts for different types of mills. The comparison is based on profitability as … mills and integrated pulp and paper mills in all energy market scenarios considered. Recovery boiler-based biorefinery … concepts including extraction of lignin or solid biomass gasification with DME production could also be profitable for market …

geographical position of such plants becomes of importance when using local biomass and delivering transportation fuel and heat. An … demand chain from biomass outtake to gas stations filling is included in the optimization. Input parameters have been studied … biomass cost, biomass availability and district heating price are crucial for the positioning of the plant and the ethanol to …

-generation biomass, i.e. lignocellulosic materials, will be possible on a large scale in the near future. Latest efforts have been … implement biorefinery on a large scale. This paper introduces and reviews the current status of research, and of the ethanol … industry in the U.S. In addition, other important concepts in biofuels, cellulosic ethanol, and biorefinery in general are …

showed that a biorefinery is a competitive alternative for a CHP-plant if the prices of biomass and market electricity are …In this study biomass-based energy production was introduced to an urban city area of Helsinki, Finland. The study … compared two cases in integration with a municipality: (1) biomass fuelled small-scale CHP (combined heat and power)-plant and …

This paper evaluates system aspects of biorefineries based on biomass gasification integrated with pulp and paper … production. As a case the Billerud Karlsborg mill is used. Two biomass gasification concepts are considered: BIGDME (biomass … integrated gasification dimethyl ether production) and BIGCC (biomass integrated gasification combined cycle). The systems …
