This study investigates the economic viability at pre-feasibility level of a hybrid methanol and biomethane plant based on biogas coupled to photovoltaic (PV) power proton exchange membrane (PEM) electrolyzer. The reference case settled in Uganda consisted two units powered by 200 kW PV grid power: 25 Nm3/h anaerobic digester 140 PEM electrolyzer-based plant. Its production 33.3 tons 70.1 per y...

Wastewater management remains a major challenge in developing countries due to the lack of adequate infrastructure, making need for economically viable and efficient technologies that can be sustained by emerging economies imperative. The upflow anaerobic sludge blanket (UASB) reactor represents an low-cost technology produces by-products from which valuable resources recovered. This study asse...

Seaweed is of importance to the environment due properties such as its CO2 sequestration capability. On other hand, plastic a versatile material important society. Unfortunately, abundance both plastics and seaweed represents challenge need adequate waste management. At first, algae might not appear suitable for energy recovery; however, with co-gasification, results are promising. This work pr...

In the study, a potentially feasible low-NOx combustion technology, based on self-sustained preheating of pulverized coal, is proposed. A 2 MW novel test rig was employed, and bituminous coal used in experiment. internal fluidized bed combustor (IFBC) as chamber for followed by air staging chamber. Preheating characteristics IFBC temperature distribution primary zone were discussed. Next, effec...

Flue gas recirculation (FGR) is a method used in several industries to control emissions and process conditions, such as NOx reduction temperature levels, increase the CO2 concentration off-gas, be better suited for methods of carbon capture. In this study, influence FGR, varying levels flue flow oxygen on polycyclic aromatic hydrocarbons (PAHs) was investigated during Si alloy production. addi...

Biomass based Indirectly Heated combined heat and power plant can be an excellent option for community scale power generation. The thermal performance of such a plant employing air-turbo generator block and bottoming steam turbine block has been analyzed over a range of pressure ratio (2-16) and for different turbine inlet air temperatures (1073, 1273 and 1373K). The conventional GT combustion ...

Infrequent structural fluctuations of a globular protein is seldom detected and studied in detail. One tyrosine ring of HPr from Staphylococcus carnosus, an 88-residue phosphocarrier protein with no disulfide bonds, undergoes a very slow ring flip, the pressure and temperature dependence of which is studied in detail using the on-line cell high-pressure nuclear magnetic resonance technique in t...

Metal hydride (MH) hydrogen storage and compression systems with near-atmospheric H2 suction pressure are necessary for the utilization of low-pressure produced by solid oxide electrolyzers or released as a byproduct chemical industries. Such should provide reasonably high productivity in modes both charge (H2 absorption at PL ≤ 1 atm) discharge desorption PH = 2–5 atm), which implies provision...

Waste tyres gasification in a bubbling fluidised bed reactor is evaluated by means of complete characterisation the product gas. The experiments are carried out at two temperatures, 700 and 850 °C, various equivalence ratios (ER) while using air as gasifying. Additionally, effect steam also studied °C. High temperature low ER increase production H2, CH4, C2H4. Steam addition mainly affects H2 C...
