Plasma gasification performances of various raw and torrefied biomass materials using different gasifying agents

Abstract

La gazéification au plasma de la biomasse ligneuse, non ligneuse et algale brute et torréfiée à l'aide de trois agents de gazéification différents (air, vapeur et CO2) est effectuée par une analyse thermodynamique. Les impacts de la matière première et de l'atmosphère de réaction sur divers indices de performance tels que le rendement du gaz de synthèse, les émissions de polluants, le rapport énergie plasmatique/production de gaz de synthèse (PSR) et l'efficacité de la gazéification du plasma (PGE) sont étudiés. Les résultats montrent que la gazéification au plasma de CO2 donne le PSR le plus bas, conduisant ainsi à la PGE la plus élevée parmi les trois atmosphères réactionnelles. La biomasse torréfiée présente un rendement accru en gaz de synthèse et en PGE, mais est plus susceptible d'avoir un impact environnemental négatif des polluants N/S par rapport à la biomasse brute, en particulier pour la paille de riz. Cependant, l'exception concerne le marc de raisin torréfié et les macroalgues qui produisent des quantités plus faibles d'espèces S dans des atmosphères de vapeur et de CO2. Dans l'ensemble, le bois de pin torréfié présente les meilleures performances pour la production de gaz de synthèse de haute qualité contenant de faibles impuretés parmi les matières premières étudiées.

La gasificación por plasma de biomasa leñosa cruda y torrefactada, no leñosa y de algas utilizando tres agentes gasificantes diferentes (aire, vapor y CO2) se realiza a través de un análisis termodinámico. Se estudian los impactos de la materia prima y la atmósfera de reacción en varios índices de rendimiento, como el rendimiento de gas de síntesis, las emisiones contaminantes, la relación de producción de energía de plasma a gas de síntesis (PSR) y la eficiencia de gasificación de plasma (PGE). Los resultados muestran que la gasificación con plasma de CO2 da el PSR más bajo, lo que conduce al PGE más alto entre las tres atmósferas de reacción. La biomasa torrefactada muestra un mayor rendimiento de gas de síntesis y PGE, pero es más probable que tenga un impacto ambiental negativo de los contaminantes N/S en comparación con los crudos, especialmente para la paja de arroz. Sin embargo, la excepción es para el orujo de uva torrefactado y las macroalgas que producen menores cantidades de especies S en atmósferas de vapor y CO2. En general, la madera de pino torrefactada tiene el mejor rendimiento para producir gas de síntesis de alta calidad que contiene bajas impurezas entre las materias primas investigadas.

Plasma gasification of raw and torrefied woody, non-woody, and algal biomass using three different gasifying agents (air, steam, and CO2) is conducted through a thermodynamic analysis. The impacts of feedstock and reaction atmosphere on various performance indices such as syngas yield, pollutant emissions, plasma energy to syngas production ratio (PSR), and plasma gasification efficiency (PGE) are studied. Results show that CO2 plasma gasification gives the lowest PSR, thereby leading to the highest PGE among the three reaction atmospheres. Torrefied biomass displays increased syngas yield and PGE, but is more likely to have a negative environmental impact of N/S pollutants in comparison with raw one, especially for rice straw. However, the exception is for torrefied grape marc and macroalgae which produce lower amounts of S-species under steam and CO2 atmospheres. Overall, torrefied pine wood has the best performance for producing high quality syngas containing low impurities among the investigated feedstocks.

يتم تغويز البلازما للكتلة الحيوية الخشبية وغير الخشبية والطحالب باستخدام ثلاثة عوامل تغويز مختلفة (الهواء والبخار وثاني أكسيد الكربون) من خلال تحليل ديناميكي حراري. يتم دراسة تأثيرات المواد الخام وجو التفاعل على مؤشرات الأداء المختلفة مثل إنتاج غاز التخليق وانبعاثات الملوثات وطاقة البلازما على نسبة إنتاج غاز التخليق (PSR) وكفاءة تغويز البلازما (PGE). تظهر النتائج أن تغويز بلازما ثاني أكسيد الكربون يعطي أقل نسبة PSR، مما يؤدي إلى أعلى نسبة PGE بين أجواء التفاعل الثلاثة. تعرض الكتلة الحيوية Torrefied زيادة إنتاج غاز التخليق و PGE، ولكن من المرجح أن يكون لها تأثير بيئي سلبي على ملوثات N/S مقارنة بالملوثات الخام، خاصة بالنسبة لقش الأرز. ومع ذلك، فإن الاستثناء هو لمارك العنب والطحالب الكبيرة التي تنتج كميات أقل من الأنواع S تحت أجواء البخار وثاني أكسيد الكربون. بشكل عام، يتمتع خشب الصنوبر المغطى بأفضل أداء لإنتاج غاز صناعي عالي الجودة يحتوي على شوائب منخفضة بين المواد الأولية التي تم التحقيق فيها.
