Abstract The objective of this project was to investigate and demonstrate production methods at a continuous, bench-scale level and generate sufficient material for an initial evaluation of a potentially profitable method of producing bioenergy and sequestering carbon. The novel process uses agricultural, forestry, and waste biomass to produce hydrogen using pyrolysis and reforming technologies conducted in a 50 kg/h pilot demonstration. The test runs produced a novel, nitrogen-enriched, slow-release, carbon-sequestering fertilizer. Seven kilograms of the material were produced for further plant growth response testing. A pyrolysis temperature profile was discovered that results in a carbon char with an affinity for capturing CO2 through gas phase reaction with mixed nitrogen-carrying nutrient compounds within the pore structures of the carbon char. A bench-scale project demonstrated a continuous process fluidized-bed agglomerating process. The total amount of CO2 sequestration was managed by controlling particle discharge rates based on density. The patent-pending process is particularly applicable to fossil-fuel power plants as it also removes SOx and NOx, does not require ene

arbon Dioxide Removal Print Page Fossil fuels are the primary sources of carbon dioxide emissions to the atmosphere. Much of the anticipated worldwide effort to reduce carbon dioxide emissions will focus on large point sources such as power plants and petroleum refineries. To contribute to this effort, RTI is actively engaged in a research and development project to develop a new process for removing carbon dioxide from industrial gas streams. RTI's process uses a solid, regenerable, sodium-based adsorbent to remove carbon dioxide from flue gases that fuel power plants. The regeneration of this sorbent produces a gas stream containing only carbon dioxide and water. Condensation separates the water out, leaving a pure carbon dioxide stream that can be used or sequestered. One of the relevant reactions based upon the use of sodium bicarbonate as the sorbent precursor is as follows: 2NaHCO3(s) Na2CO3(s) + CO2(g) + H2O(g) RTI has developed a 2-reactor system for removing the carbon dioxide. Both the adsorption of carbon dioxide and regeneration of the sorbent take place at low temperature (under 150°C). Laboratory experiments at RTI have demonstrated multiple cycles of the adsorption and regeneration phases. In addition, we have developed process information on * Effect of operating conditions * Effect of other feed stream components * Reaction kinetics * Heat and material balances from proc
