Syngas from biomass gasification is being developed for alternative feedstock in the chemical industry. Palm kernel shell which generated palm oil industry can be potentially used as raw material process. The purpose of this study was to investigate use modified natural zeolite catalysts steam shells. Mordenite type by acid leaching a tar cracking catalyst. Steam conducted at temperature range ...

Dinamika pembalikan magnetisasi pada nanoblock berbasis kobalt teredam kuat yang distimulasi oleh pemanasan pulsa telah dieksplorasi secara numerik untuk model parallelepiped dengan ukuran 50×50×20 nm3. Pengaturan simulasi diimplementasikan mengevaluasi dua parameter penting dalam perekaman magnetik bantuan panas, yaitu stabilitas termal, dan konsumsi medan tulis. Stabilitas termal diukur melal...

This study quantifies the effluents generated during processing in three industry types, estimates energy potential from quantified form of biogas generation, and determines economic viability recovered. Data were procured relevant scientific publications to quantify production processes types examined, using industrial process calculations. The effluent data are used 2-module recovery model es...

This study probed the effect of water potential (Ψ) on anaerobic methane production and a microbial consortium. The Ψ level investigated digester (n = 20) was in range from −0.10 to −2.09 MPa with mean value −1.23 MPa, significantly correlated SCOD, TKN, NH4+-N, alkalinity, salinity (SPS), NH4+, Na+, K+, Cl−, NO3−, PO43− (p < 0.001). maximum rate (Rm) Control (−0.40 MPa) 8.11 mL day−1 decrea...

Aiming at the problems such as low CBM utilization rate caused by concentration with methane content less than 8% extracted from a small coal mine in Hancheng mining area, Shaanxi Province, and serious environmental pollution coal-fired hot blast stove for heating, heat storage oxidation heating technology of ultra-low gas was studied combining field investigation balance calculation, regenerat...

Gasification system performance generally depends on feed moisture content, activity of bed material, gasifier and combustor temperatures, scrubber media. The tar concentration gas composition product are two indicators the gasification performance. In this research, effects temperature material produced from a dual fluidized (DFB) power plant were investigated. DFB is located in Nong Bua distr...

This study was carried out to estimate the relevance of biological supplementation in improving economic efficiency anaerobic digestion (AD). Three kinds silages—maize, grass, and igniscum—were initially inoculated with digestate then supplemented one four vaccines containing different bacteria species (APD®, PPT®, JENOR®) or a yeast mold mixture (HAP®). In addition, each plant silage fermented...

The objective of the present study was to experimentally investigate and compare characteristics three oxygen-enhanced combustion (OEC) methods; premix enrichment (PE), air-oxy/fuel (AO), additionally also oxygen lancing (OL) method. overall concentration varied from 21% 38%. Combustion tests were carried out using gas burner with thermal input 750 kW fired by natural gas. OEC methods, such as ...

Under the current requirements of environmental protection, carbon peaking and neutrality goals, capacity new energy interconnection network is increasing day by day. The thermal power unit requires ability rapid load adjustment to meet real-time balance. However, when in a variable condition, denitrification system inefficient or even inoperable. nitrogen oxide emission large, which makes it d...

Due to the necessity of developing renewable energy sources, anaerobic digestion for producing biomethane has developed significantly in last years, since it allows both reduce disposal treatment and produce green energy. In this field, fruit vegetable wastes have been recently put forward, they could represent a suitable resource as new frontier within context circular economy. This study aims...
