摘要： A method for circulating a cooled regenerated catalyst comprises the following steps: a regenerated catalyst derived from a regenerator (5) is cooled to 200-720° C. by a catalyst cooler (8A), which either directly enters into a riser reactor (2) without mixing with hot regenerated catalyst, or enters the same after mixing with another portion of uncooled hot regenerated catalyst and thereby obtaining a hybrid regenerated catalyst with its temperature lower than that of the regenerator; a contact reaction between a hydrocarbon raw materials and the catalyst is performed in the riser reactor (2); the reaction product is introduced into a settling vessel (1) to separated the catalyst and oil gas; the separated catalyst ready for regeneration is stream-stripped in a stream stripping phase (1A) and enters the regenerator (5) for regeneration through charring; after cooling, the regenerated catalyst returns to the riser reactor (2) for recycling.

摘要： Provided are a method for the catalytic conversion of hydrocarbons with a downer reactor and a device thereof. The specific process of the method is as follows: a raw material of hydrocarbons after being pre-heated (or not) and a low-temperature regenerant from a regenerant cooler entering an entry end of a downer reactor, flowing down along the reactor for reactions such as catalytic cracking, and a mixture of a reactive oil and gas and a catalyst descending to the end of the reactor for rapid separation, thereby achieving the rapid separation of the catalyst and the oil and gas. The main operation conditions thereof are as follows: the reaction temperature is 460 to 680° C., the reaction pressure is 0.11 to 0.4 MPa, the contact time is 0.05 to 2 seconds, and the weight ratio of the catalyst to the raw material (a catalyst-to-oil ratio) is 6 to 50. The separated catalyst to be regenerated (abbreviated as a spent agent) is stripped by means of a stripper, and enters a regenerator and is burned for regeneration, wherein the regeneration temperature is controlled at 630-730° C. The regenerant from the regenerator enters the regenerant cooler to be cooled to 200-720° C., and then enters the downer reactor for recycling

摘要： This describes an apparatus comprising a plate with a number of elements having a hydrophilic surface arranged in an array with an overlay having a hydrophobic surface. A height of the overlay is between about 5% and 100% of the diameter of the elements. The application also discloses a wall circumferential to the plate; and a removable grid insertable into the apparatus, said grid comprising dividers enclosing a number of through-holes, said through-holes spaced in the grid to allow alignment of the through-holes of the grid over the elements in the plate when said grid is inserted into the apparatus, said dividers of the grid inserted into the apparatus form sides of wells bottomed by the plate and at least one element on said plate.

摘要： A method and apparatus to proxy notification service connections between a mobile client and a notification server. In one embodiment of the invention, a proxy receives a proxy setup request for the notification service from the mobile client. The proxy further establishes a notification connection with the notification server for the mobile client and maintains the notification connection without waking an application processor of the mobile client. The proxy receives a notification from the notification service and forwards the notification to the mobile client.

摘要： A method of iteratively adjusting a color of light emitted by a light source includes setting a weighted target color to an initial color of a light emitted by a light source. The method further includes determining a target color of the light by a color controller to iteratively adjust a color of the light to the target color of the light. The method also includes determining an updated weighted target color as a combination of a portion of the weighted target color and a portion of the target color. The method further includes adjusting the color of the light by the color controller to the weighted target color.
