Özet:

 

In this study, conversion of seaweeds into hydrochars was   investigated with the aim of obtaining a renewable energy feedstock. The   seaweeds Fucus serratus and Alaria esculenta,  and a mixture of seaweeds, mainly consisting of Cystoseria sp... and   Laurencia sp..., were subjected to hydrothermal carbonization (HTC) in subcritical water   at three different temperatures: 200, 225, and 250 ∘∘^{\circ}C. Fuel   characteristics and chemical properties of the derived hydrochars were   determined using the standard fuel analysis and spectroscopic methods. The   combustion behavior of seaweeds and hydrochars was examined via   nonisothermal thermogravimetric analysis under air atmosphere. The   seaweed-derived hydrochar yields were lower than those of the   lignocellulosic-derived hydrochar yields in the literature. Hydrochars   derived from Fucus serratus and Alaria esculenta became increasingly similar to lignite with higher process   temperature. Fucus serratus-derived hydrochars had the highest calorific value due to   their higher carbon content and significantly lower ash content. HTC   converted the seaweeds to hydrochars with improved combustion   characteristics observed by lower burnout temperature and higher reactivity   during combustion. The slagging index values of hydrochars implied medium or   high slagging potential during combustion. On the other hand, HTC resulted   in hydrochars with reduced fouling index implying medium fouling potential   during their combustion due to the significant removal of alkali metals.
