Abstract
Conversion technology will continue to evolve. These developments started from the industrial revolution 1.0 to the industrial revolution 4.0, but in these developments even though technology solves a problem, it has the potential to cause new problems such as environmental problems. Environmental problems that can occur starting from energy conversion that is not environmentally friendly as well as the use of several technologies that cause pollutants that are quite dangerous if high intensity can even cause health problems, acid rain and climate change. The pyrolysis process has been proven capable of converting municipal solid waste (SPP) into bio-oil (BO) where most of the BO produced is hydrocarbon fuel with light oil (naphtha) and diesel types. Many studies have been carried out by various groups, but the raw materials used are single SPP components such as plastic, biomass, tire rubber, paper and not the real SPP. Therefore, this research was conducted to see the effect of using variations in zeolite catalyst concentration on the bio-oil produced. Variations in zeolite catalyst concentration are divided into concentrations of 0.25; 0.5; 0.75 and 1. For the pyrolysis test, it was carried out at a temperature of 400 ° C, with a reaction time of 60 minutes. From the results of experiments that have been carried out, the most ideal concentration for producing the most bio-oil products is at a concentration of 0.5. This indicates that the more catalysts are used in the pyrolysis process, the more syngas products will be produced. So the use of catalysts in the pyrolysis process can increase thermal efficiency and the pyrolysis process can be carried out at low temperatures for the production of bio-oil from mixed waste. If following national oil needs and these reserves continue to be exploited, Indonesia will only have oil reserves for the next 7-8 years or until 2028. Another problem is that the use of conventional fuel oil will produce large amounts of CO2 and will make a major contribution to climate change and global warming.
