This research aimed to determine the chemical composition of Rawapening, Semarang District, Indonesia water hyacinth and to study the effect of pyrolysis time on the volume of liquid smoke products. The water hyacinth was cut into pieces with a size of about 2 cm to 3 cm, and placed in pyrolisator. A total of 700 g of water hyacinth sample was fed into the pyrolysis. The product was observed for its content of hemicellulose, cellulose and lignin. The pyrolysis was carried out at a temperature of 117 °C, 400 °C and 683 °C. The results showed that water hyacinth contains hemicellulose 36 % d.b, cellulose 21 % d.b and lignin 7 % d.b which it potential to be a raw material for liquid smoke production. The effect of temperature was significant on liquid smoke products. It was proven that the higher the pyrolysis temperature, the greater the liquid smoke produced. The liquid smoke was obtained for 0.2 mL per 100 g, 12.3 mL per 100 g and 16.3 mL per 100 g dried biomass water hyacinth at a temperature of 117 °C, 400 °C and 683 °C, respectively.

“…The HHV of tar for beet pulp calculated from the energy balance was equal to 21.6 MJ/kg (Figure 6a). For comparison, during pyrolysis of energy crops [57] and wood waste [58], tar was characterized by HHV in the range from 23 to 27 MJ/kg. In our research, the addition of defecation lime has reduced the HHV of tar.…”

Co-Pyrolysis of Beet Pulp and Defecation Lime in TG-MS System

The process of pyrolysis of beet pulp, a by-product after the extraction of raw sugar from sugar beet, with the addition of defecation lime was studied in a thermobalance coupled with a mass spectrometer. The beet pulp pyrolysis process took place completely at 600 °C, and the resulting char, tar and gas were characterized by higher heating values of 23.9, 21.6 and 7.77 MJ/kg, respectively. The addition of the defecation lime to beet pulp caused both an increase in the char production yield and a decrease in the tar production yield. At the same time, the higher heating value of char and tar decreased along with the increase of defecation lime added to the sample. The deconvolution of derivative thermogravimetric (DTG) curves allowed us to identify the basic components of beet pulp, for which the activation energy by isoconversion method was calculated. The 20 wt.% addition of defecation lime caused an increase of the activation energy by about 18%. Further increase in the defecation lime content resulted in a reduction of activation energy. At the temperature above 600 °C, calcination of calcium carbonate contained in defecation lime occurred. The CO2 produced during calcination process did not cause auto-gasification of char.

The growth of eceng gondok (Water hyacinth) in Rawa Pening Lake showed rapid increase.. Based on the mandate of the National Lake conference in Bali and the 16th World Lake Conference, Rawa Pening is one of the fifteen national lakes which need to be treated for its conservation. Reducing number of eceng gondok plants is one of the alternatif. However, further processing is required to treat the waste of eceng gondok. One attempt is to convert eceng gondok (water hyacinth) into liquid smoke product. This article reviewes the potency of eceng gondok for liquid smoke through pyrolisis method. The liquid smoke can be used for various applications such as preservatives, antioxidants, biopesticides and perisa disinfectants. Pyrolysis is a combustion process in the absence of oxygen to produce liquid and charcoal activated charcoal products called activated charcoal. The pyrolysis process is generally carried out at a temperature range between 200-700 °C. The pyrolysis process is one of the methods chosen in order to strive for development that suppresses the formation of CO gas but releases water vapor. Pyrolysis at a temperature of 300-700 ° C, produces the most dominant compounds 1.6 Anhyro-beta-d-glucopyranose, phenol, and acetic acid. The reaction that occurs during pyrolysis of this temperature is the release of water vapor instead of carbon gas so that it is safe for the environment. The discussion on this article focused on the production of liquid smoke from eceng gondok biomass.
