20140065045 | PROCESSES FOR SELECTIVELY REDUCING THE CONCENTRATION OF HYDROGEN CYANIDE IN SYNGAS - This invention pertains to processes for selectively oxidizing hydrogen cyanide contained in syngas using permanganate anion as an oxidant contained in an aqueous solution that is contacted with the syngas under certain conditions of temperature, pressure and duration of contact. | 03-06-2014 |
20140147360 | Method and Apparatus for Reactive Gas Remediation - Disclosed are methods, materials, apparatus and systems for removing or suppressing ambient levels of reactive gas contaminants, particularly acidic gases, using particles of zeolite, sepiolite or other suitable carrier material impregnated with at least one treatment compound selected to react with the acidic gas(es). The methods involve contacting a contaminated gas stream with the impregnated carrier materials whereby at least a portion of the reactive gases contacts the treatment compound and reacts, thereby consuming the reactive gas molecules. | 05-29-2014 |
20140241969 | PROCESS OF REMOVING HCN FROM FLUE GAS - The invention includes a process for reducing the amount of HCN discharged to atmosphere from a FCC unit, having a regenerator and a means for collecting and supporting catalyst particles. The process comprises adding a catalyst to the regenerator flue gas prior to entering the collecting means and precipitating the catalyst in the collecting means to form a catalyst bed. Ammonia or ammonia precursor is optionally added to the flue gas. The flue gas HCN is reacted in the presence of water and oxygen in the flue gas, and optional ammonia or ammonia precursor, at 200° C. to 800° C. in the presence of the catalyst bed to reduce the HCN amount, and the flue gas containing a reduced amount of HCN is discharged to atmosphere. The catalyst is one or more supported transition or lanthanide metal catalysts. The process can also be utilized in any combustion process. | 08-28-2014 |
20140369915 | CATALYST FOR HYDROLYSIS OF CARBONYL SULFIDE AND HYDROGEN CYANIDE AND USE OF TITANIUM DIOXIDE-BASED COMPOSITION - Provided are a catalyst for hydrolysis and use of a titanium dioxide-based composition which are capable of removing COS and HCN simultaneously at high degradation percentages. The catalyst for hydrolysis is a catalyst for hydrolysis of carbonyl sulfide and hydrogen cyanide, having at least: an active component containing, as a main component, at least one metal selected from the group consisting of barium, nickel, ruthenium, cobalt, and molybdenum; and a titanium dioxide-based support supporting the active component. | 12-18-2014 |
