The present invention relates to resin compositions for treatment of a subterranean formation. In various embodiments, the present invention provides a method of treating a subterranean formation. The method can include obtaining or providing a resin composition that includes a hardenable composition including a hardenable resin. The resin composition also can include a hardening composition including a water control hardening agent. The method can include contacting a subterranean material downhole with the resin composition, and reacting the hardenable composition and the hardening composition, to give a hardened resin composition. In some embodiments, the resin composition provides both particulate consolidation and water control.

A rotating grill platform functional as an independent grill unit or placeable on a grill and that incorporates a stationary lower grill platform with a rotator Fan attached to it in a manner to draw air comprised of smoke and cooking vapors from the grilling chamber and to recirculate the air back to the grilling surface to provide substantially uniform heat distribution for the food being cooked, with the blade tilting mechanism designed to increase or decrease the grill platform rotational speed as per user preferences and the cooking requirements. The grill platform is compact, lightweight, versatile and does not require gas or any Electric power, but can operate in a self sustaining manner.

Buffers of YMCK colors have memory capacities for storing image data corresponding to a difference between timings at which YMCK images formed on YMCK photosensitive drums are transferred onto a transfer member and control is effected such that paper is fed only when all image data sets to be printed are stored in the respective YMCK buffers.

A number of pre-casted elements are stacked vertically to build the tower, while parts of the elements are forming the tower wall. Each element of the tower is fixed on its position and is connected with a tower foundation by a number of assigned post-tensioned cables. These cables are running inside the tower and they are pulled through the tower without embedding in dedicated channels. The post-tensioned-cables are fixed at certain points with the tower wall via damper-means to prevent their oscillation.

The invention discloses a method for regenerating a denitration catalyst by utilizing a waste SCR (Selective Catalytic Reduction) catalyst recovery liquid. The method comprises the following steps: after soot blowing, cleaning and drying pretreatment on a waste SCR catalyst, smashing the waste SCR catalyst into powder; evenly mixing the powder with calcium carbonate to obtain a mixture; roasting the mixture to obtain a roasted material; re-smashing the roasted material to obtain a re-smashed material and adding the re-smashed material into a dilute sulphuric acid solution; adjusting the value of pH to 8-11 by ammonium hydroxide; filtering for separating out titanium-containing residues and thus obtaining a recovery liquid; after soot blowing, cleaning and drying pretreatment on an inactivated SCR catalyst block body, soaking the block body in the recovery liquid; drying the block body; roasting the block body in a muffle furnace with the temperature of 400-600 DEG C, thereby obtaining the regenerated SCR catalyst with denitration activity being recovered. The method organically integrates catalyst recovery and regeneration technologies. The precious metal components of the waste SCR catalyst are fully utilized, the problem of vanadium, tungsten or molybdenum separation-purification is avoided, the recovery and regeneration technology process is shortened, and the treatment expenditure of the waste SCR denitration catalyst is lowered.

The present invention relates to a portable colorimetry for examining multiple-form chlorine in water and photoelectric color comparator thereof. The colorimetery employs the color reaction of DPD and sterilization chlorine agent in water to determining multiple-form chlorine content derived from sterilization chlorine agent, which includes employing glycine masking free chlorine, employing potassium iodide catalyzing and chemical combining chlorine to participate in color and employing phosphate buffer solution. The weight matched granule DPD, potassium iodide, EDTA and phosphate are packed into two reagent bags respectively, DPD and phosphate granules are packed in the reagent bag 2, DPD, potassium iodide, EDTA and phosphate granules are packed in the reagent bag 3; the free chlorine inwater is determined by reagent in reagent bag 2, the total chlorine in water is determined by reagent in reagent bag 3, and then the chemical combination chlorine content is calculated. The colorimetry and photoelectric color comparator of the present invention can determine the surplus chlorine, total chlorine, combination chlorine, chlorine dioxide and chlorite salt in water immediately, rapidly and flexibly after sampling in site.
