En este trabajo se presenta un nuevo método para medir la potencia de haces de luz generada por láseres de CO2 de flujo rápido transversal. Éste consiste en la medición de la temperatura del gas antes y después de la zona de descarga en las condiciones cu... see more

Biogas adalah salah satu sumber energi terbarukan yang dapat dimanfaatkan sebagai pengganti energi fosil. Biogas sebagian besar mengandung metan (CH4) dan karbon dioksida (CO2). Kandungan CO2 pada biogas mengurangi efisiensi pada proses pembakaran dan dap... see more

The increase of atmospheric CO2 gas can cause the increasing of earth’s surface temperature. This is one ofphenomena that ensues as global warming. Global warming occurred because of excess greenhouse effects (morethan normal conditions) of the atmosphere... see more

Hydrogen is an environment-friendly fuel and has a high caloric value. Hydrogen as a molecule is not found in nature, but it is found in compounds with other elements. Besides catalytic steam reforming of natural gas, hydrogen can also be produced from th... see more

Producing active charcoal to be absorbent for ion Fe2+ and Co2+ had been done by using waste of bagasse. The objective of study was to utilize waste of bagasse to be active charcoal, so it can be used for absorbent. Initially, it was carbonized by using p... see more

AbstrakPada penelitian ini dilakukan pengolahan limbah sekam padi menjadi biokar sebagai zat aditif dalam mortar yang berperan sebagai absorben gas CO2 di dalam mortar. Tujuan penelitian ini selain untuk memanfaatkan limbah sekam, tetapi juga untuk menget... see more

Hollow fiber membrane contactor is nowadays one of the alternative absorption processes for conventional bubble columns. In this work, the performances of microporous hollow fiber membranes for aeration and CO2 absorption were investigated. The membranes ... see more

Carbon dioxide capturing processes from industrial gases are widely applied to enrich valuable gas and to reduce green-house gas emission. The highest amount of anthropogenic CO2 is emitted in flue gas form. Flue gas composition varies in a wide scale the... see more

Fossil fuel reserves are increasingly depleting and non-renewable. The choice of utilizing alternative energy sources that are renewable and environmentally friendly is a very smart thing to do. Biogas is a renewable energy and is environmentally friendly... see more
