20140271383 | METHODS FOR REMOVING IRON MATERIAL FROM A SUBSTRATE - Methods of removing iron from a catalytic converter having an accumulation of one or more iron compounds and regenerating a catalytic converter are provided. A catalytic converter having an accumulation of one or more iron compounds embedded or deposited thereon can be treated with a substantially aqueous alkaline solution in which the substantially aqueous alkaline solution includes an antioxidant. | 09-18-2014 |
20120190533 | METHOD FOR TREATING FLUE GAS CATALYST - A method for treating a catalyst base that comprises a contact area of porous material. A fluid, such as a flue gas stream, can be conducted along the contact area. A catalytically relevant substance is introduced into pores of the catalyst base using a transport fluid and remains on pore wall areas after removal of the transport fluid. The introduction is carried out such that an amount of the catalytically relevant substance relative to the surface remains on the pore wall areas as a function of location within the pore and decreases within the pore after exceeding a specific pore depth. A blocking fluid can first be introduced into pore regions beyond the specific pore depth, thus blocking these regions when transport fluid containing the catalytically relevant substance is introduced. | 07-26-2012 |
20120117969 | METHOD FOR OPERATING A POWER PLANT - A method for operating a hybrid power plant comprising fuel-operated heating and solar energy heating of carrier fluids, wherein a first portion of total power provided by the power plant is based on fuel-operated heating of carrier fluids and a second portion of the total power is based on solar energy heating of carrier fluids, the heat absorbed by a solar energy heated carrier fluid is transferred to a carrier fluid circuit of a fuel-operated part of the power plant. When a sudden increase or reduction of the total power provided by the power plant is required as compared to a basic state, the second portion is first increased or reduced over a short time period in order to provide a positive or negative reserve power. Subsequently, the first portion is slowly increased or reduced and the second portion based on solar energy heating is correspondingly reduced or increased again. | 05-17-2012 |
