Abstract

Corn waste is the result of agricultural production that can be further utilized and get additional economic for the community. Waste Corn cab is one of Indonesia abundant biomass apart from. The utilization of biomass by implementing pyrolysis process can be viable solution. This study aims to observe the determination corn cab pyrolysis using HCL-bentonite activation and without bentonite towards syngas product (CH4-H2-CO-CO2). Updraft reactor was utilized for 30 minutes pyrolysis process. We used MQ4, MQ8, MQ7 coupled with Arduino UNO for measuring CH4, H2, CO2 and CO in ppm unit. Compared without bentonite, the result showed that methane (CH4) gas production increased. In addition, we found also that hydrogen (H2) gas increased respectively. Not mention, the content of CO increased.

Abstract

Rice husk is a type of agricultural waste that generated from rice production activities. The number continues to increase in line with the increasing food needs of the people in Indonesia. This study aims to determine the effect of the addition of natural zeolite as a catalyst and to determine the effect of natural zeolite mass percentage variation in the mixture on rice husk waste catalytic combustion by using the thermo gravimetric analysis method. The results of this study show that there is an effect of adding natural zeolite catalysts with the mass percentage of natural zeolite variations on the combustion characteristics and activation energy of each mixture. Increasing the mass percentage of natural zeolite catalysts can affect the reaction process become faster and minimize the effort required, but it was found that if the amount of natural zeolite catalyst is too much, it only adds to the heating load which causes slower reaction. The mixture of rice husks with 10% natural zeolite catalyst is the most optimal mixture because it has the lowest required activation energy value and the combustion reaction phases are achieved at a lower temperature than 5% and 15% mass percentage variations.

Abstract

Fouling menjadi permsalahan pada proses produksi di suatu industri, terutama industri yang memiliki prosesperpindahan panas. Fouling dapat mengurangi perpindahan panas yang terjadi. Oleh karena itu terjadinyafouling harus diatasi dengan cleaning yang cepat. Untuk mempercepat proses cleaning, terutama pada foulingdengan material droplet minyak nabati dapat dilakukan dengan memanfaatkan sifat wettability. Sifatwettability dapat diatur dengan mengatur temperatur pada droplet. Tujuan analisis ini adalah mengetahuifaktor-faktor yang berpengaruh pada wettability, sehingga dapat dipakai untuk memudahkan proses cleaning. Berdasarkan analisis, diperoleh kesimpulan bahwa wettability dipengaruhi oleh temperatur minyak nabatiserta kerataan permukaan substrate-nya.
