Description
Technical field
The present invention relates to a kind of catalyst aging stove, particularly relate to and in laboratory, carry out catalyst aging, be applicable to evaluate a kind of ageing oven of the hydrothermal stabilities such as molecular sieve, catalyzer.
Background technology
Catalyzer is extremely extensive in field application such as oil, chemical industry.Many catalysis process all complete under catalyst action.The quality of catalyst performance directly affects product yield and product quality, and therefore, the catalyzer of development research superior performance is very important.In the R&D process of catalyzer, to the evaluation of catalyst performance and other character, need various experimental provisions and process to complete, and wherein the aging of catalyzer is the first step of carrying out all kinds of evaluations of catalyzer.
As active in catalytic cracking fresh catalyst high and unstable, not representative.When laboratory study and evaluate catalysts, in order to make catalyzer reach fast equilibrium activity, conventionally adopt the aging method of high temperature hydro-thermal, make the quick deactivation of catalyzer.General with 100% water vapour at high-temperature pressure or add to depress and measure the index that activity change is usingd as stability, the actual conditions that each catalyzer manufacturing plant adopts is different, but is divided into substantially aging and harsh aging two kinds of mitigation.Relax aging temperature mostly at 780 ℃-800 ℃, harsh aging temperature is at 795 ℃-815 ℃, and digestion time changes greatly, and when aging temperature is high, the time is shorter; When temperature is lower, the time is longer.By hydrothermal aging micro-activity, measure stability and the activity that can reflect catalyzer.So fresh catalyst need to be processed a period of time through high-temperature water vapor, then measures its activity index, it is a kind of method generally adopting at present.
Traditional catalyst aging experimental provision once at most can aging 4 samples, and testing sample is essential through a series of processing.As compressing tablet, fragmentation, the operation such as grind, sieve, then get a certain amount of 20-40 order solid catalyst particle in stainless steel cup, be stacked in successively in aging pipe, upper and lowerly respectively put again a stainless steel cup that porcelain ring is housed, play insulation effect.When aging temperature rise to 800 ℃ and stable after, the timing of manually intaking; Water vapour enters from aging pipe bottom, one by one through sample cup, from aging pipe top, discharges, and digestion time one arrives, and system automatically opens air valve air inlet cooling and power-off stops aging.The method is because aging stainless steel cup is stacked in aging pipe up and down successively, bottom water inlet steam, therefore, have that upper and lower aging severity is different, a problem such as sample, water vapour channel in lower sample exhaust gases, and need to carry out a series of numerous and diverse artificial treatment to testing sample.CN101424601A has disclosed a kind of catalyst aging method, has both selected the calciner with centre rotational axis, and sample is placed on turning axle surrounding (putting 2 layers, a plurality of samples), with axle, rotates, and rotating driver is arranged on calciner bottom; Turning axle adopts upper and lower two end supports, two elevated-temperature seal points; Before catalyst aging, first with air, make medium, when temperature is raised to 400 ℃～800 ℃, switch water vapour, water vapour enters from calciner upper end, air is cut out simultaneously; Start timer, set digestion time, after predetermined digestion time, device cuts out water vapour automatically, and ageing process finishes.This invention is compared with traditional aging method, once can aging a plurality of samples, and all samples can experience identical temperature and time in whole ageing process, to eliminate because of the different aging severity difference causing in position in calciner, work efficiency and aging quality have been improved.But the method adopts the method for top water inlet steam, and in calciner, water vapour exists air-teturning mixed phenomenon, and the waste gas of the aging generation of sample can cause and influence each other sample; Turning axle adopts upper and lower two end supports, strong point apart from each other, and right alignment precision prescribed is high, and manufacturability is poor; In addition, two elevated-temperature seal points, reduce device processing safety.
