Patent number: 9919269Abstract: A method and apparatus for cleaning and recycling stack gas from coal-fired power plants, from natural or propane burning heating plants, or from cement kilns by using renewable catalysts of zeolite to separate pollutants into recyclable and reusable materials. The method reduces from the stack gas carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxide (NOx), sulfur oxide (SOx) as well as halogens such as chloride and fluorides and trace metals particularly, mercury, lead, and zinc.Type: GrantFiled: March 11, 2016Date of Patent: March 20, 2018Assignee: 3D Clean Coal Emissions Stack LLCInventor: James Gary Davidson

Patent number: 9737849Abstract: A method and apparatus for cleaning and recycling stack gas from coal-fired power plants, from natural or propane burning heating plants, or from cement kilns by using renewable catalysts of zeolite to separate pollutants into recyclable and reusable materials. The method reduces from the stack gas carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxide (NOx), sulfur oxide (SOx) as well as halogens such as chloride and fluorides and trace metals particularly, mercury, lead, and zinc. The method and apparatus also result in production of fertilizer products by purging with gaseous or liquid nitrogen the zeolite beds through which the stack gas flows. The oxygen generated may be recycled to the burners in the plant.Type: GrantFiled: May 27, 2015Date of Patent: August 22, 2017Assignee: 3 D Clean Coal Emissions Stack, LLCInventor: James Gary Davidson

Patent number: 9067837Abstract: A method and apparatus for cleaning and recycling stack gas from coal-fired power plants, from natural or propane burning heating plants, or from cement kilns by using renewable catalysts of zeolite to separate pollutants into recyclable and reusable materials. The method reduces from the stack gas carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxide (NOx), sulfur oxide (SOx) as well as halogens such as chloride and fluorides and trace metals particularly, mercury, lead, and zinc. Bauxite compounds can also be separately collected if desired. The method and apparatus also result in production of fertilizer products by purging with gaseous or liquid nitrogen the zeolite beds through which the stack gas flows. The oxygen split in the beds may be recycled to the burners in the plant.Type: GrantFiled: March 14, 2014Date of Patent: June 30, 2015Assignee: Three D Stack, LLCInventor: James Gary Davidson

Publication number: 20140260471Abstract: A method and apparatus for cleaning carbon oxides, sulfur oxides and nitrogen oxides, from stack gas, from combustion of coal, combustion of natural gas or propane, or from a cement kiln by reaction using calcium zeolite and sodium zeolite catalysts. The method also includes cleaning the catalytic beds with nitrogen to remove the collected reactants and recover a fertilizer product and the catalysts for reusable.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: THREE D STACK, LLCInventor: James Gary DAVIDSON
