“…In this process, the methanotrophs use the in situ generated O 2 by algae to convert CH 4 into biomass while generating CO 2 that is subsequently fixed by the algae. Such a process offers several advantages over the methanotrophs and methanotrophs-HOB processes: i) it does not require an external O 2 supply, ii) CH 4 [71] Notes:…”

“…3 supplemented with vitamin solution of DSMZ medium 81 4 originated from a mesophilic AD fed with agricultural wastes (pumpkin and pig manure) As seen in Taking into account the above-mentioned issues, if SCP products are going to be marketed for direct consumption as human food, it will have to go thru a long journey of the regulatory approval process. First, they must undergo a number of proper treatments to disrupt the cellulosic cellular wall and reduce nucleic acid content to a level that meets the guidelines for the use as food or food supplements, without affecting the quantity and quality of the amino acids.…”

“…A wide range of waste types can be used as feedstock for biogas production. For instance, sludge from water resource recovery facilities (WRRFs) [3], agricultural residues [4][5][6][7], paper waste [8,9], food waste [10], and livestock manure [11,12]. The yield and composition of biogas from AD depend largely upon the type of feedstock and operating conditions [13,14].…”

Biogas is a mixture of mainly CH 4 and CO 2 , which can be generated from anaerobic digestion of organic materials. The use of biogas is mostly limited to thermal energy and electricity generation. However, the abundance of cheap shale gas and solar energy could drive out biogas for such applications in the near future. Hence, alternative applications of biogas have recently received great attention among researchers across the globe. This review, for the first time, discusses the feasibility of the bioconversion of biogas to value-added products, including single cell protein as animal feed supplement, and methanol that is an important building block in the chemical industries. Mechanisms of the process, microorgnisms involved and key parameters affecting their efficiency are discussed in detail. Some future research needs are suggested in order to deepen our understanding of these biochemical processes.

“…In these power plants, energy optimization is an important aspect regarding the decrease in the fuel consumption rate [2]. Energy consumption is an important parameter to reflect a country`s development stages and its communities living standards [3]. Power plant efficiency is a critical and important parameter regarding the decrease in fossil fuel consumption rate as it is a primary energy source for power generation, industry, and transportation [4].…”

Exergy analysis is an important tool to identify the improvements in various industrial processes. In this study, the existing steam power plant is examined based on energy and exergy analyses. The steam network in the power plant is comprised of two sections, one of them is used for paddy drying, while other portion is used to operate the turbine for in-house electricity production. Mass, energy, and exergy balances are applied to individual equipment of the plant. The power plant is modeled and simulated using Aspen HYSYS® V10. The calculated thermodynamic values are used for in-depth analysis of the power plant. Case-studies are included in this study to show the effect of various operational parameters on the process efficiency. The analysis shows that the boiler is the major source of exergy destruction, because of the incomplete combustion process, and inappropriate insulations. The remedial actions are also suggested in the study.

Summary Catalytic effects in fast pyrolysis of low‐rank coal and coal tar conversion were investigated in a two‐stage fixed‐bed reactor over HZSM‐5 zeolite and Mg/HZSM‐5. Mg/HZSM‐5 caused the lower total tar yield and the higher non‐condensable gas yield but the fraction of light tar (boiling point below 360°C) increased to allow a slightly higher total yield of light tar. It also exhibited good catalytic activity and increased the species of light tar than HZSM‐5 zeolite. The light tar fraction was increased from 45 to 74.6 wt% than without catalyst (66%) at the pyrolysis temperature of 600°C. Ex‐situ catalytic fast pyrolysis over Mg/HZSM‐5 also lowered the contents of element N and S in the resulting coal tars by 29% and 15% respectively. The corresponding increase in the content of element H and molar ratio of H to C of the resulting coal tars was reported as 17% and 13% respectively. The addition of Mg into HZSM‐5 increased the ability of the catalyst for inhibiting coke deposition.
