Embodiment 1

[0055] We prepared five different charcoals from peanut shells at different temperatures (900°C, 600°C, 500°C, 450°C, and 400°C) in a hypoxic environment. In each case, the samples were heated to the target temperature for 1 minute. The sample is heated to a certain temperature and then allowed to cool. The material was then ground and sieved to less than US 30 mesh and greater than US 45 mesh, and a 20.0 gram sample was prepared. Formulated 48% NH 4 NO 3 (ammonium nitrate) aqueous solution. Each sample was soaked for 5 minutes, poured into cone filter paper and allowed to air dry for 24 hours. Then pour 100 ml of tap water (pH 8) into the conical filter paper for rinsing. The pH of each rinse was measured and showed a corresponding decrease in pH with the leaching rate of each material.

[0056] Except for the sample prepared at 400°C, the differences were small for the other samples. After three or four rinses, material carbonized at higher temperatures will stabilize...

Embodiment 2

[0061] Although this method can be used for a variety of structures, this example uses relatively simple production techniques. In this example we use CO which is easily adaptable to any gas flow and injection 2 and a mechanically fluidized bed of ammonia hydrate. A charge of 250 g 30-45 mesh (0.4-0.6 mm) 400°C charcoal was added regularly at 15-30 minute intervals. Higher rotational speeds increase fluidization and suspend particles until particles are deposited due to NH 4 HCO 3 becomes too heavy to be supported by the fluidizing airflow. Longer time intervals produce larger particles. The particle range was 1.0-2.0 mm at 10-15 minutes and 3.0-6.00 mm at 20-30 minutes. The interior of the particles was then examined under a scanning electron microscope. Inner pore structure shows significant NH formation at 10-15 min 4 HCO 3 structure. The pores and cavities of the resulting material were completely filled at 20-30 minutes.

Abstract

This invention relates a series of steps to provide an economical production of a carbon based fertilizer and soil amendment made during the capture of greenhouse gases from the combustion of fossil and non fossil fuels. The invention uses biomass and other carbonaceous sources through pyrolytic conversion to gases and charcoal, to allow for the further production of co-products, such as hydrogen and ammonia. The invention also relates to the combination of hydrated ammonia, combustion flue gas exhaust, and charcoal, provide for the conversion of the charcoal into a valued added soil amendment to return essential trace minerals and plant nutrients to the soil. The ability to produce a large volume carbon co-product while removing mandated emissions and producing renewable based hydrogen provides an economic gain to a large number small and large businesses and increase the chance of achieving significant reductions in greenhouse gas emissions.

Description

[0001] Cross-Referenced Related Applications [0002] Pursuant to 35 U.S.C.Sec. 119(e), applicant hereby asserts that the application filed on October 22, 2002 entitled "Production of Soil Amendment by Combined Generation of Hydrogen, Synthesis of Carbon, and Utilization of Waste Gases Containing Carbon Dioxide and uses" of U.S. Provisional Patent Application 60 / 420,766, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to the production and use of a nitrogen-enriched carbon-based fertilizer and soil conditioner that uses said charcoal with ammonia, carbon dioxide, water and other Formed by the reaction of components commonly found in flue gas emissions. The present invention also relates to the optimization of the minerals and phytonutrients of this charcoal to produce and use the combined material as a soil amendment and fertilizer. The invention also relates to the use of this material as a method of economi...
