“…H2 composition showed an opposite tendency with the CH4 composition because the steam methane reforming reaction uses CH4 to produce H2. The results depicted that the composition change in syngas was consistent with the literature studies [23,[48][49][50]. The optimal S/B ratio was determined as 1.5 considering the higher amounts of H2 and CO compositions and the lower amount of CO2.…”

Energy production is facing the environmental and economic issues due to growing population and uncertainties about the fossil fuels. These concerns prompt the researchers to find widely available and renewable alternative such as biomass instead of the fossil fuels. Microalgae is one of the promising biofuels owing to its rapid growth speed and higher calorific value. Steam gasification is an alternative way converting biomass to syngas with higher H2 and lower CO2 content compared with the other thermochemical conversion processes. In the present work, the downdraft gasifier model was developed by using Aspen Plus® program that has the capability to investigate the performance of microalgae gasification. Before the performance evaluation of the gasification, validation of the model successfully completed and exit gas compositions of H2, CO2, CO and CH4 were found very close for experimental study and the developed model. Effects of the main parameters of the process such as steam/biomass ratio and gasification temperature were assessed on the syngas composition and higher heating value (HHV) of syngas. The obtained results were stated that the increment in the temperature showed great effect on the H2 and CO compositions of syngas, they increased from 50.72% to 56.47% and 28.11% to 28.84% respectively. The simulation results also illustrated that the rising of the S/B ratio was favored the steam related reactions and increased the H2 content in syngas. However decreasing trend of the CH4 caused reducing of the HHV of syngas as a function of temperature and steam as well.

“…Temperatur yang digunakan dalam proses gasifikasi tentunya menjadi faktor yang mempengaruhi komposisi syngas yang dihasilkan. Hal ini tentunya berkaitan dengan jenis reaksi yang digunakan dimana reaksi gasifikasi tentunya terdiri dari 2 jenis yaitu reaksi endotermik maupun reaksi eksotermik (Kartal & Özveren, 2021). Efek dari perubahan temperatur dilakukan dengan memvariasikan nilai temperatur pada aliran steam dari 300℃ hingga 1100℃.…”

Batubara merupakan salah satu potensi sumber energi yang menggantikan minyak bumi sebagai sumber energi dan bahan baku untuk industri kimia di indonesia. Sekarang ini, sumber batubara di indonesia diestimasikan mencapai 61 juta ton dan 80% dari itu adalah batu bara peringkat rendah (low rank coal). Permasalahan pada penelitian ini ialah untuk mengetahui bagaimana pengaruh dari beberapa faktor seperti temperatur, tekanan, serta aliran massa terhadap syngas yang dihasilkan. Selain itu yang ingin diketahui dari penelitian ini ialah untuk menentukan berapa energi yang dapat dihasilkan dari produksi syngas terhadap energi yang diperlukan dalam proses gasifikasi. Proses gasifikasi batubara untuk menghasilkan syngas yang baik memerlukan kondisi dari berbagai parameter tersebut sehingga optimasi sistem gasifikasi perlu dilakukan untuk menghasilkan syngas dengan kualitas yang baik. Syngas yang baik dapat diketahui dari nilai rasio H2 dan CO yang dapat diatur dengan mengubah parameter reaksi. Model yang digunakan pada penelitian ini telah dirancang dengan menggunakan 2 komponen reaktor untuk menjalankan reaksi gasifikasi serta didorong oleh berbagai komponen pendukung seperti kompresor. Metode optimasi yang dilakukan ialah dengan melakukan variasi nilai dari setiap parameter yang ada didalam pemodelan yang dirancang dengan 3 sampel berbeda dengan kode sampel CQ004, CQ005, dan CQ008. Penentuan jumlah energi yang dihasilkan dapat diketahui dengan mengasumsikan produk syngas tersebut digunakan sebagai bahan bakar dengan reaksi pembakaran sehingga dapat diketahui berapakah energi yang diperoleh dari produk syngas tersebut dan akan dibandingkan dengan nilai energi yang diperlukan dalam produksi.

Energy is a prerequisite for any nation's industrial, social, and economic advancements. [1][2][3][4] Energy can broadly be categorized into renewable and nonrenewable energies. Nonrenewable energies are energy that cannot be replenished over a short period. Examples of such energy are coal, nuclear energy, natural gas, and crude oil. Renewable energies, in contrast, are those energies that are replenishable over a short period. This form of energy includes solar, hydro, tidal, wind, biomass energy, etc. Biomass energy is the energy generated from biomass materials. Biomass material could be woody (such as teak, mahogany), nonwoody (such as agro-residues, industrial waste), and animal materials. [5] Agroresidues are described as all organic materials that are generated as byproducts from agricultural activities. These byproducts constitute the main part of biomass feedstock's total annual production, which forms an essential and sustainable source of energy for industrial and domestic applications. [6] They are material that are of benefit to humankind, though their economic benefits are less than the cost of transformation for advantageous use. [7] Agro-residues can be divided into residues generated on the field and residues generated during the processing of agricultural products. [8] Field-based residues include but are not limited to tobacco stalks, maize stalks, sugar cane tops, rice straw, soybean straw/pods, and cocoa pods. In contrast, process-based include peanuts shell, rice husk, maize cob, bagasse, and coffee husk. Agro-residues are available in large quantities in an area with a high level of agricultural activities. [9] In developing nations, major agricultural activities are recorded in the rural areas, resulting in a larger quantity of agro-residues in these areas. [10,11] Most of the time, the farmers in developing nations' dump these residues in an open field or
