“…Pyrolysis can be defined as thermal decomposition of organic material in inert condition (without the presence of oxygen) that causes the formation of volatile compounds. Pyrolysis up to 170 0 C results in the drying and vaporizing water content, while it results in hemicellulose decomposition at 200-260 0 C, cellulose decomposition at 260-310 0 C, lignin decomposition at 310-500 0 C, and secondary reactions as oxidation, polymerization and condensation ones at upper 500 0 C [4][5].…”

The total content of phenol compounds present in the liquid smoke can be extracted either by using polar or non-polar solvents. Polar and non-polarsolvents are often used to extract phenol compounds from plants. Extraction of phenol compounds was performed by using ethyl acetate and hexanesolvents at 40° C, 55° C and 70° C within 60, 120, and 180 minutes. The highest total content of phenol compounds is obtained through extractionprocess at 70o C within 180 minutes using ethyl acetate solvent, which is 103,394 mg/g. While, the lowest one is obtained through extraction processat 40o C within 60 minutes using hexane solvent, which is 13,697 mg/g. The phenol compounds obtained are syringol and guiaicol compoundsusing ethyl acetate solvent within 180 minutes, at the temperature of 70o C, which is 5,44% and 3,97%.

“…They found out that pyrolysis of coconut shells forms liquid smoke containing 46,56 % phenol compounds and 12,93 % acid. Besides, there are also groups of liquid smoke components, which are water (11-92 %), phenol (0,2-2,9 %), acid (2,8-9,5 %), carbonyl (2,6-4,0 %) and tar (1-7 %) [4].…”

This study aims to modify the pyrolysis device that produces bio-oil with methyl esters, determine the content of methyl esters with GC/MS analysis, and test the performance of biodiesel using a diesel engine. This research modified the pyrolysis tube wall by changing the thickness of the stainless-steel material to 1.5 mm to facilitate the combustion process and heat transfer and reduce the equipment weight. Meanwhile, the tube base still uses 3 mm stainless steel to prevent leakage during the process because of high temperature (300 – 400°C). Using wood and coconut shell could accelerate the incomplete combustion process and produce higher methyl ester than using a gas stove. The process using wood and coconut shell could produce 35.88% of bio-oil produced while the process using a gas stove only produces 30%. The GC/ MS analysis has discovered that the content of methyl ester and ethanol was 60.12% and 1.13%, respectively. The obtained methyl ester was separated from the tar using a rotary evaporator based on the boiling point difference. Methyl ester from this husk can turn on the diesel engine with B20-B60.

This study aimed to investigate the use of water hyacinth to produce liquid smoke. The study observes the temperature and time variables of yield, pH, density, and refractive index in the production of liquid smoke from water hyacinth. The sequence of the work is as follows: first, water hyacinth was cut into 5 cm sections and then sun-dried for 2–3 d, depending on the weather. Next, 550 g of dried water hyacinth was added to the pyrolysis reactor. The temperature variations were 200°C, 400°C, and 600°C, and the time variations were 1, 4, and 7 h. As a result, liquid smoke was produced with varying yield, pH, densities, and refractive indices. The best results in this research are liquid smoke pyrolysis at a temperature of 400°C and 4 h with the acquisition of a yield of 93 mL, pH 2–4, a density of 1.080,8 gr/mL, and a refractive index of 1.339,6, with chemical component 41.45% total acid, 2.44% phenol and 56.10% carbonyl.
