NOVELTY - Garbage into natural gas conversion involves sorting garbage collected from an area into household garbage and restaurant sludge that is classified into waste plastics, waste paper and catering waste containing high organic matter content and less water. Waste plastics and waste paper are treated by using gasification-based catalytic system to produce hydrogen and carbon monoxide. Hydrogen and carbon monoxide are reacted to generate methane (natural gas) and carbon dioxide. Remote plasma generator is switched on. Water boiler steam tank is opened by using valve.    USE - Method for converting garbage into natural gas (claimed) used for large scale processing domestic garbage.    ADVANTAGE - The method enables conversion of garbage into natural gas in economical and eco-friendly manner.    DETAILED DESCRIPTION - Garbage into natural gas conversion involves sorting garbage collected from an area into household garbage and restaurant sludge that is classified into waste plastics, waste paper and catering waste containing high organic matter content and less water. Waste plastics and waste paper are treated by using gasification-based catalytic system to produce hydrogen and carbon monoxide. Hydrogen and carbon monoxide are reacted to generate methane (natural gas) and carbon dioxide. Remote plasma generator is switched on. Water boiler steam tank is opened by using valve. The steam tank is connected with carbon dioxide deaerator and remote plasma generator. Water, carbon dioxide and oxygen are generated by treating garbage by using gasification-based catalytic system. Garbage is sorted and crushed by passing it to screw compressor vacuum feeder using conveying belt. Crushed garbage is treated using gasification system to obtain reaction gas. Obtained gas is supplied to steam turbine to generate steam. The steam is supplied to remote plasma generator. Obtained gas is purified by desulfurization and dechlorination. Purified gas is supplied to hydrogen separator to collect hydrogen. Obtained hydrogen and carbon dioxide are passed to methane synthesizer to generate methane. Hydrogen and carbon dioxide is supplied to remote plasma generator to produce carbon black product. Multiple reactions are carried out in gasification-based catalytic system. Carbon black obtained from organic waste is reacted with carbon dioxide to produce carbon monoxide. Carbon black obtained from organic waste is reacted with water obtained from vapor to produce carbon monoxide and hydrogen. Carbon monoxide is reacted with steam to produce carbon dioxide and hydrogen. Carbon black obtained from organic waste is reacted with oxygen to produce carbon dioxide which is then decomposed to produce carbon and oxygen. Carbon monoxide is reacted with oxygen to produce carbon dioxide. Hydrogen is reacted with oxygen to produce water. Carbon dioxide produced is passed through heat exchanger and then through remote plasma generator which is connected with screw compressing and feeding device of garbage gasification system. Multiple reactions are carried out in gasification-based catalytic system. Carbon obtained from organic waste is reacted with carbon dioxide to produce carbon monoxide. Carbon obtained from organic waste is reacted with oxygen to produce carbon dioxide. Carbon monoxide is reacted with oxygen to produce carbon dioxide. Carbon monoxide is reacted with hydrogen to produce natural gas. Obtained liquefied natural gas from methane synthesizer tank is dehydrated. Remaining garbage i.e. food, and sludge containing high organic matter content and less water are fermented to produce marsh gas. Methane is separated from marsh gas using gas separator. Gas monitoring sensor, remote pressure sensor, and fermentation pool with acidity temperature and humidity monitor and power supply are switched on using remote sensor. Sludge containing organic matter garbage is crushed into feeding device which is connected to fermenting tank. Each batch processing pool is fermented at 20-45 degrees C for 5-30 days and pH of fermented liquid is adjusted to 7.0-8.5. Biogas methane is separated from fermentation tank using water purifier, separating machine, hydrogen storage tank, nitrogen storage tank or hydrogen sulfide separator. Residue of biogas is used as fertilizer. Carbon dioxide (25-50%) produced is re-circulated to fermenting tank to produce oxygen and carbon black.
