There has been a rise in the published literature on the utilization of crops for bioenergy production in Louisiana. However, very few scholarly documents have used Geographic Information Systems (GIS) to map the distribution of potential bioenergy crops in Louisiana. This study seeks to fill the void by evaluating the potential of bioenergy crops in Louisiana for energy production using GIS. Given this objective, the agricultural census data for 1999, 2009, 2019, and 2020 obtained from the U.S. Department of Agriculture were used in the analysis. The quantities of various crops produced in the state were loaded into an attribute table and joined to a shapefile using ArcGIS software. The symbology tool’s graduated option was used to create five maps representing each of the annual gasoline price variation with respect to years is statistically significant (p < 0.05). This suggests that gasoline prices will generally rise despite a price drop over the years. The paper concludes by outlining policy recommendations in the form of assessing the availability and viability of other crop types, such as wheat, oats, and rice, for energy production in the state.","PeriodicalId":71705,"journal":{"name":"可持续生物质能源系统(英文)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70427379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MNPs were synthesised by co-precipitation and used in the \u0000hydrothermal liquefaction (HTL) of water hyacinth at different reaction conditions \u0000(temperature, reaction time, MNPs to biomass ratio and biomass to water ratio). \u0000The best reaction conditions were as follows: temperature— 320, reaction time—60 minutes, MNPs to biomass ratio – 0.2 g/g and \u0000biomass to water ratio – 0.06 g/g. HTL in \u0000presence of MNPs gave higher biocrude yields compared to HTL in absence \u0000of MNPs. The highest biocrude yield was 58.3 wt% compared to 52.3 wt% in \u0000absence of MNPs at similar reaction conditions. The composition of biocrude oil \u0000was analysed using GC-MS and elemental analysis. GC-MS results revealed that \u0000HTL in presence of MNPs led to an increase in the percentage area corresponding \u0000to hydrocarbons and a reduction in the percentage area corresponding to oxygenated \u0000compounds, nitrogenated compounds and sulphur compounds. Elemental analysis \u0000revealed an increase in the hydrogen and carbon content and a reduction in the \u0000nitrogen, oxygen and sulphur content of the biocrude when HTL was done in \u0000presence of MNPs compared to HTL in absence of MNPs. The nanoparticles were \u0000recovered from the biochar by sonication and magnetic separation and recycled. \u0000The recycled MNPs were still efficient as HTL catalysts and were recycled five times. The application of MNPs in the HTL of \u0000water hyacinth increases the yield of biocrude oil, improves the quality of \u0000biocrude through removal of hetero atoms, oxygen and sulphur compounds and is a \u0000potentially economical alternative to the traditional petroleum catalysts since \u0000MNPs are cheaper, widely available and can be easily recovered magnetically and \u0000recycled.

The primary objective of this work was to produce fuel briquettes from homogeneous and heterogeneous combinations of carbonized maize cobs, Bamboo poles and charcoal dust. For the primary objective to be achieved, the main activities which were performed included; chopping bamboo poles, sorting maize cobs, carbonization, crushing, binder preparation, mixing, extrusion, drying and quality assessment of the fuel briquettes. The maize cobs and charcoal dust used for this work were purchased from the farmers and charcoal sellers respectively from the districts of Luwero and Nakaseke. Bamboo poles were provided by Divine bamboo group. The homogenous combinations included 100% maize cob char, 100% bamboo char and 100% charcoal dust. Heterogeneous combinations included 75% bamboo char + 25% charcoal dust and 25% bamboo char + 75% charcoal dust. The test results for both homogenous and heterogeneous combinations of fuel briquettes had ranges of moisture content 8% - 11%, Volatile matter 12% - 23%, Ash content 33% - 39%, Heating Value 16 - 22 MJ/Kg, Fixed Carbon 30% - 51% and moisture content 8% - 9%, Volatile matter 13% - 19%, Ash content 27% - 44%, Heating Value 16 - 18 MJ/Kg, Fixed Carbon 30% - 51% respectively. The test results for drop resistance, density and Compressibility strength for both homogeneous and heterogeneous combinations had ranges of 7% - 56%, 214 - 941 kg/m3, 0.077 - 0.544 N/mm2 and 12% - 28%, 869.1 - 958.3 kg/m3, 0.124 - 0.295 N/mm2 respectively. These results were within the ranges reported in the literature especially for the heterogeneous combinations. Therefore, there is the possibility to use bamboo woody feedstock in combination with other agricultural waste feedstock for the production of fuel briquettes. We can increase the quality and production of fuel briquettes by using alternative feedstock sources rather than degrading the environment through deforestation.","PeriodicalId":71705,"journal":{"name":"可持续生物质能源系统(英文)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47650781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The following mixtures were carried out: FW with CD respectively at different ratios 100:0% (A), 80:20% (B) and 60:40% (C); FW with MW at the following ratio 80:20% (D); FW with CD and MW respectively at these ratios 80:10:10% (F) and 60:20:20% (G).
