Evaluations were conducted at two irrigation levels, 100% of plantation application and at a 50% deficit.

Napier Grass is Effective Feedstock for Biomass Power

Mar 08, 2017 · Sunbird Bioenergy (SL) has successfully completed a series of trials to test the suitability of locally sourced sustainable biomass feedstock to produce power in the company’s 32 MW power plant. The boilers were originally designed for bagasse, but in order to extend the power production beyond the sugarcane harvesting season, the company has tested other sustainable feedstock including

Integrated environmental and economic ashaiqisments of

Napier grass had lower global warming (GW) impacts and biomass delivery costs, 34–153 kg CO₂ eq. per oven-dry metric ton (ODMT) and $51–$57 perODMT, respectively than that of energy cane. However, both the energy crops provided carbon sequestrations (−17 and −232 kg CO₂ eq. ODMT⁻¹) and thus net GW impact varied between 51 and (−14) kg CO₂ eq. ODMT⁻¹ based on the treatments.

Comprehensive Charachaiqization of Napier Grass as a - MDPI

Apr 24, 2015 · Study on Napier grass leaf (NGL), stem (NGS) and leaf and stem (NGT) was carried out. Proximate, ultimate and structural analyhaiqi were evaluated. Functional groups and crystalline components in the biomass were examined. Pyrolysis study was conducted in a thermogravimetric analyzer under nitrogen haiqiphere of 20 mL/min at constant heating rate of 10 K/min. The results reveal that Napier grass

Biofuel and valuable products recovery from Napier grass pre

Apr 01, 2019 · According to Mohammed , the ratio of energy output to energy input in the pyrolysis system with Napier grass as feedstock is about 0.22, with biomass drying stage accounting for about 84% of the total energy consumption. This process requirement was attributed to the physicochemical charachaiqistics of the biomass as a freshly harvested Napier

BELOWGROUND IMPACT OF NAPIER AND GUINEA GRAShaiqi GROWN FOR

2010). Total root biomass of more than 3000 and 1600 g m-2 in 0-60 cm depth has been reported for napier and guinea grashaiqi respectively in Gangtok, India with mid altitude subtropical climate (Singh, 1999a, Singh, 1999b). Compared to annual crops such as corn and soybeans, napier and guinea grashaiqi are perennial and can be ratooned for as many as

Investigation of the potentials of southwest Nigerian Napier

Sep 01, 2021 · This study showed that Napier Grass store chemical energy more in form volatiles than fixed carbon. The ultimate analysis showed that Napier Grass has lower carbon contents, 42.73 % than Nigerian coal species which ranged from 59 to 84.7 % . Carbon dioxide (CO 2) is produced when the carbon in haiqi fuels is burnt in the presence of oxygen

Multi-Disciplinary Ashaiqisment of Napier Grass Plantation on

Dec 07, 2021 · Napier grass is an energy crop that is promising for future power generation. Since Napier grass has never been planted extensively, it is important to understand the impacts of Napier grass plantations on local energetic, environmental, and socioeconomic features. In this study, the soil and water ashaiqisment tool (SWAT) model was employed to investigate the impacts of Napier grass plantation

Thermochemical charachaiqization of napier grass as an energy

Jun 07, 2016 · (2016). Thermochemical charachaiqization of napier grass as an energy source and its environmental and economic benefit analysis. Energy Sources, Part B: Economics, Planning, and Policy: Vol. 11, No. 2, pp. 130-136.

Environmental performance ashaiqisment of Napier grass for

Nov 01, 2017 · In addition to Napier grass, waste from palm oil production is also a potential bioenergy feedstock in Thailand. Comparison between Napier grass and palm cultivation revealed that the UEV of Napier grass was lower than that for palm oil which means that less resources are used to produce one joule of biomass.

Catalytic Intermediate Pyrolysis of Napier Grass in a Fixed

Mar 29, 2016 · The environmental impact from the use of fossil fuel cum depletion of the known fossil oil reserves has led to increasing interest in liquid biofuels made from renewable biomass. This study presents the first experimental report on the catalytic pyrolysis of Napier grass, an underutilized biomass source, using ZSM-5, 0.3HZSM-5 and zinc exchanged zeolite-A catalyst. Pyrolysis was conducted in

Economic and environmental impact ashaiqisments of a stand

Aug 16, 2019 · The use of Napier grass as a feedstock decreased the global warming potential (GWP) of the medium-sized CHP (i.e., 13 MWe) plant by 73–92 % compared to that of a coal and natural gas-fired CHP plants. Other environmental impacts were also reduced by 24–100 %. Eutrophication was the only impact comparable to that of the coal-fired CHP plant.
