PİROLİZ GAZINDAN ANAEROBİK FERMANTASYON YÖNTEMİ İLE TAR ARITIMI

Bugünün en önemli tartışmalarından biri Enerji dönüşüm teknolojileri ve temiz enerjidir. Son on yılda, enerji dönüşüm teknolojilerinin hızlı gelişimi gözlenmektedir. Bu gelişme sırasında birçok enerji üretim teknolojisi bulunmuş ve araştırılmıştır. Bunlardan biri, piroliz ve gazlaştırma gibi biyokütle termal dönüşümdür. Bununla birlikte, bu tür dönüşüm sistemleri ile ilgili önemli bir sorun, ürün gazı yan ürünü olan katran miktarı ve konsantrasyonudur. Katran, gazlaştırma ve piroliz gibi termal dönüşüm sistemlerinin yan ürünü olarak ortaya çıkan sistemlerde sorunlara neden olan istenmeyen bir yan üründür. Katran sistemde, çiğleşme noktasının altındaki sıcaklıklarda yoğuşarak reaktör, boru ekipmanları ve diğer sistem ekipmanları üzerinde birikerek ısı kayıplarına, korozyona, kurum oluşumuna, katalitik zehirlenmeye ve boru ve kanallarda tıkanıklığa neden olur. Bu çalışmada, biyogaz ve piroliz sistemlerinin kombine çalışması ile yeni bir katran parçalanması sistemi tasarlanmıştır. Piroliz reaktörü ve biyogaz reaktörü sistemde birbiriyle bağlantılı olarak çalıştırılır. Katran miktarı, 10, 20 ve 30 L'lik piroliz gazında sırasıyla 0.159, 0.194 ve 0.165 g / L olarak gravimetrik analiz yöntemi ile belirlenmiştir. Bu çalışmanın temel amacı, literatüre yeni bir katran parçalanmasını sağlayan biyolojik arıtım yönteminin kazandırılmasıdır. Bu sistemde katran yan ürünü ve piroliz gazı biyogaz reaktöründen geçirilerek verim %55.08 , %56.01 ve %56.09 olarak hesaplanmıştır. Burada en yüksek verim %56.09 olarak tespit edilmiştir.

One of the most significant current discussions in today is the Energy conversion Technologies and clean energy suppliers. The past decade has been viewed the rapid development of energy conversion technologies. During this development, many energy production technologies have been found and researched. One of them is biomass thermal conversion systems, which are examined under three titles as pyrolysis, gasification and combustion. However, the major problem of thermal conversion systems is tar amount and composition in the product gas. The tar is a side product and causes problems in the systems emerging as the by-product of thermal conversion systems such as gasification and pyrolysis. Tar is condensed below dew point temperature and accumulated in the system and causes heat losses, corrosion, soot formation, catalytic poisoning, and congestion in pipes and ducts. In this study, a new tar removal system has been designed with the hybrid operation of biogas and pyrolysis systems. The pyrolysis reactor and the biogas reactor are operated in connection with each other in the system. The amount of tar was determined via gravimetric analysis method as 0.159, 0.194 and 0.165 g/L respectively in the pyrolysis gas of 10, 20 and 30 L. The main purpose of this study is to examine the effects of biological treatment method, which is a new method in tar treatment, and also to add a new hybrid treatment method to the literature. In this system, the pyrolysis gas, which has tar content, was passed through the biogas reactor and the yield was calculated as 55.08 %, 56.01 % and 56.09%. The highest yield was calculated as 56.09 %.
