Daher erfordert das Ziel der Europ&auml;ischen Union, bis 2050 klimaneutral zu sein, eine Umstellung der W&auml;rmeerzeugung in den n&auml;chsten Jahrzehnten.</p>

<p>Durch den Einsatz von Bioraffineriekonzepte k&ouml;nnen die erforderlichen Prozessketten bereits innerhalb des n&auml;chsten Jahrzehnts realisiert werden, da sie auf Technologien aufbauen, die zum Teil bereits im Pilot- und Demonstrationsma&szlig;stab verf&uuml;gbar sind. Der Fokus liegt dabei auf den</p>

<p>Einsatz von Opportunity Fuels, also Einsatzstoffe f&uuml;r die keine oder nur geringe Kosten anfallen, zur Erzeugung von BioSNG.</p>

<p>In diesem Projekt wird die Datengrundlage f&uuml;r den der technologische Nachweis der DFB Dampf-Gaserzeugung vom Pilot- bis zum 1 MW-Ma&szlig;stab erbracht und die Technologie von TRL 3 auf TRL 5 angehoben.</p>

<p>Zus&auml;tzlich wird eine Online-Messung f&uuml;r Teere entwickelt, die eine verbesserte Prozess&uuml;berwachung erm&ouml;glicht. Durch Untersuchungen zu katalytischen Zentren auf dem Bettmaterial werden weitere Erkenntnisse &uuml;ber Effizienzsteigerungen der gesamten Prozesskette geliefert. Zudem wird eine neuartige Methanisierungstechnologie (katalytische Methanisierung im Laborma&szlig;stab, bestehend aus drei polytropen Festbettreaktoren mit Zwischenk&uuml;hlung) untersucht, die f&uuml;r die Aufbereitung zu BioSNG und weitere Einspeisung in das Erdgasnetz verwendet wird.</p>

<p>Insgesamt werden zwei Prozessketten zur Nutzung von biogener Reststoffen zur W&auml;rmeerzeugung f&uuml;r die Industrie demonstriert. Insbesondere der Weg &uuml;ber BioSNG bietet eine niedrige Einstiegsh&uuml;rde, da die vorhandene Erdgasinfrastruktur genutzt werden kann. Im Gegensatz dazu kann die direkte Verbrennung von Produktgas in Industriebrennern mit minimalen Anpassungen des Brenners umgesetzt werden. W&auml;hrend die BioSNG-Nutzung einen direkten biogenen Substituten f&uuml;r fossile Brennstoffe bietet, erm&ouml;glicht die direkte Produktgasverbrennung eine einfachere Prozesskette zur Herstellung des Energietr&auml;gers. Im Zuge des techno-&ouml;konomischen Assessments wird die geeignete Prozesskette f&uuml;r die jeweilige Anwendung evaluiert.</p>

<h3>Ziele</h3>

<p>Ziel des Projektes ist die Untersuchung der biobasierten Opportunity Fuels in der DFB-Dampfgaserzeugung und die weitere Optimierung des Prozesses durch gezieltes Betriebsmonitoring zur Erzeugung eines brennbaren Produktgases. Dar&uuml;ber hinaus wird die Erzeugung von BioSNG auf Basis des Produktgases mit dem Fokus auf einen stabilen, last- und rohstoffflexiblen Betrieb angestrebt. Dies f&uuml;hrt zu einem technischen und &ouml;kologischen Proof-of-Concept der gesamten Prozesskette.</p>

	'content_en' => '<p>Heat production in large industry sectors (steelmaking, cement production, etc.) is currently primarily dependent on fossil fuels. As the European Union has committed itself to be climate neutral by 2050, a shift in heat production has to be realised over the next decades. Establishing bio-refineries based on opportunity fuels builds upon already partially developed technologies, which are available in pilot- and demonstration-scale. Thus, a realization of such process chains can be achieved already within the next decade.</p>

<p>By following a step-by-step technology development research, the current level of knowledge will be significantly increased and the data basis for further</p>

<p>development can be provided. Hence, the technological proof for gasification from pilot- to 1 MW-scale is achieved within this project, raising the technology from TRL 3 to TRL 5. Additionally, an online measurement for tar species will developed, allowing for easier performance monitoring. The investigations into the catalytic centers on bed material will give further insight in how to increase the efficiency of the whole process chain. A novel methanation technology (laboratory-scale catalytic methanation consisting of three polytropic fixed bed reactors with intermediate cooling) will be investigated which will be used for the investigation of the gasification product gas upgrading to bioSNG ready for the injection into the natural gas grid.</p>

<p>Two process chains utilizing biogenic biomass to produce heat for industry will be showcased. Especially the route via bioSNG provides a low barrier of entry since existing natural gas infrastructure can be use. In contrast, direct combustion of product gas can be implemented in industry burners with minimal adaptions to burner geometry. While bioSNG utilization offers a direct biogenic substitute for a fossil fuel, direct product gas combustion allows for an easier process chain to produce the energy carrier. Hence, the suitable process chain is dependent on the individual application and is evaluated by the techno-economic assessment.</p>

<p><img alt="" src="/webroot/files/image/Projektseite/BioHEAT_klein.jpg" /></p>

<p>The project aims the investigation of the utilization of bio-based opportunity fuels in DFB steam gasification and the further optimization of DFB steam gasification by optimized operation monitoring to produce a combustible product gas. Furthermore, the generation of bioSNG based on DFB steam gasification and subsequent combustion or methanation with a focus on a stable, load flexible and feedstock flexible operation is targeted. This leads to a technical and environmental proof-of-concept of the full process chain</p>

				'abstract' => '<div class="c-article-section__content">
<p>The pulp and paper industry represents an industry sector which is characterised by its already high degree of sustainability. Biomass is a renewable input material, and typically highly developed recovery cycles minimise the loss of chemicals used in the pulping process. However, certain parts of the recovery cycle are still operated on fossil fuels. This study deals with the substitution of the fossil-based gaseous fuel with product gas from biomass gasification.</p>

<p>Gasification experiments have shown that bark available at pulp and paper mills is suitable to produce a product gas via dual fluidised bed steam gasification as a promising substitute for natural gas. Based on the comparison of process layouts regarding the separation of non-process elements, separation efficiency is derived for different setups. To ensure operational security of the chemical recovery cycle, comprehensive gas cleaning including heat exchangers, a particle filter, and a liquid scrubber unit is advised. The gas flow of fuel gas into the gas burner is increased as the heating value of the product gas is accordingly lower in comparison to natural gas. Furthermore, adaptions of the gas burner might be necessary to address the earlier ignition of the H<sub>2</sub>-rich product gas compared to natural gas.</p>
