PENGARUH VARIASI SUDUT KONDENSOR (0⁰, 15⁰, DAN 30⁰) TERHADAP HASIL PIROLISIS LIMBAH BAN LUAR SEPEDA MOTOR DENGAN DEBIT AIR PENDINGIN 18 LPM
Abstract
The development of industrial world of rubber usage nowadays increasingly
make waste motorcycle tire waste become very common and is a solid waste
dangerous for environment. The disposal of used tires at the disposal site will be a
major problem as disposable tires will fill the exhaust space and become a hotbed
of mosquitoes and become a source of disease. Tires have complex structures that
make it very difficult to recycle because old tires are very difficult to break down
by bacteria or microbiological structures. In an effort to help overcome the problem
of waste tires used the research to convert waste tires used pyrolysis to get oil that
can be used for fuel.
In this study the main material used in the form of waste motorcycle tires
outside 3 kg. In each experiment the outer tires of motorcycles are cut into pieces
of approximately 16 x 5 cm. testing of motorcycle tire outbreaks with a heating
temperature of 300-350 ° C generated from a gas stove with 3 kg LPG gas the time
spent on each experiment is 100 minutes. Cooling water discharge of 18 LPM,
angle variation used in this research is 0⁰, 15⁰, and 30⁰.
The results showed that the highest heat transfer rate was obtained at a 30⁰
angle of 451.44 Watt, after which the angle of 15⁰ was 413.82 Watt and the angle
of 0⁰ was 401.28 Watt. At an angle of 30 ° 386 ml of oil with a residual ash weight
of 399 g, an angle of 15 ° yields 376 ml of oil with a grain weight of 383 g, and an
angle of 0 ° producing 359ml oil with ash weight of 367 g. Characteristics of
pyrolysis tire oil obtained with density value of 0.913 gr / ml, viscosity value of
5.07-5.57 mPa.s, calorific value of 9654.98 Cal / g, and flash point of 56-61 ° C.
