Narrow Results

The aim of this study was to illustrate the methane gas impacts on AL-Russifa region, Jordan, in addition to the opportunities and obstacles faced. AL-Russifa city suffers serious health and environmental problems as a result of the methane gas emissions from Al-Russifa Landfill.

The uncontrolled methane emissions and the potential of collection, use for producing electricity and the existing activities that include the biogas plant and regulations were analyzed and recommendations presented. The required institutional management and social structure that promote the proper management of solid waste that affect methane emissions need to be advanced through technological exchanges and training programs. Improving the existing biogas project and the establishment of new ones can reduce green house gases while generating electricity; thus reducing Jordan's dependency on imported oil.

The lack of financial, technical expertise and awareness among public and private sectors, in addition to the bureaucracy and the short time pay back phenomena are all considered as constraints for achieving such prosperous environmental projects. Establishing upgraded institutions will need to embrace improved capability to generate replicable projects that serve as a vehicle for solving pollution problems and promoting sustainable development.

Ni/CuO-ZrO₂-CeO₂-Al₂O₃ catalysts were prepared by co-precipitation method at pH 9 and using Na2CO3 as the precipitant. The Ni loading (mass fraction) of the catalysts was 10%. The coke deposition and active sites of catalysts were characterized by XPS. The results of coke deposition, active sites and evaluation of catalytic performance indicated that autothermal reforming of methane on Ni/CuO-ZrO₂-CeO₂-Al₂O₃catalyst to H₂, CO and CO₂ followed direct reaction mechanism and CO and CO₂ were direct products of reaction.
