The invention relates to a CO medium-high-pressure low-temperature sulfur-tolerant pre-shift catalyst and a preparation method thereof, and relates to the technical field of sulfur-tolerant pre-shift catalyst preparation. In the CO medium-high-pressure low-temperature sulfur-tolerant pre-shift catalyst, an active component is a binary component of a cobalt-containing compound and a molybdenum-containing compound; a carrier raw material is a composition of boehmite and nano-grade titanium dioxide; and a rare earth auxiliary agent is a mixture of a lanthanum-containing compound and a cerium-containing compound. The CO medium-high-pressure low-temperature sulfur-tolerant pre-shift catalyst provided by the invention has the characteristics of high strength, high stability, high erosion resistance, high toxin resistance, uniformly active component dispersion, and good shift activity stability. The active component is not prone to loss. The invention also provides the simple and feasible preparation method of the catalyst.

The invention relates to a protective agent for a sulfur tolerant shift catalyst. The protective agent comprises a carrier and an active component, and is characterized in that attapulgite clay is used as a main carrier material and added with a powdered solid compound containing magnesium; and the active component is a binary component containing copper and nickel, and added with an active auxiliary agent, which is one or more selected from zinc oxide, iron oxide, chromium oxide, zirconium oxide and corresponding soluble salts thereof. The invention adopts a kneading method to prepare the protective agent, and employs attapulgite clay with wide source and low cost as the raw material. The protective agent not only has the advantages of simple preparation process and low cost, but also has good adsorption detoxification on toxics such as arsenic (As), hydrocyanic acid and carbonyl compounds in the sulfur tolerant shift catalyst. The protective agent can be used in harsh conditions such as high pressure, high space velocity and high water-air ratio, has strong adsorption capacity on ash and toxics in synthetic gas production from heavy raw materials such as residuum, heavy oil, petroleum coke and coal, and can effectively protect the main shift catalyst and prolong the service life of the main shift catalyst.

An image glossiness controller has a main component color specifying unit that identifies a prescribed component color and output identification information thereof. A change in amplitude of a convexoconcavity of a toner layer of the prescribed component color is greatest among those of the other component colors when each of the component color toner is formed and fixed alone. Three or more halftone dot signal generators convert clear toner image information into three or more binary clear toner image signals corresponding to three or more component colors per component color pixel using multiple halftone dot characteristics, respectively. Each of the multiple halftone dot characteristics generating three or more binary clear toner image signals has a reversed phase from that generating three or more binary component color image signals.

The invention relates to a process of a binary component high-silica glass fiber wetting agent. The process is characterized by selecting brand new components of the wetting agent, namely a film forming agent, a lubricating agent, a surface active agent, an emulsifier and the like so as to give a good lubricating effect to binary component high-silica fiber during the spinning process and upgrade the stability of the fiber to atmospheric action.

The present invention provides a method for invoking a binary component in Javascript, the method comprising: the Javascript engine obtains the character string in the Javascript statement and determines whether it is a Javascript language node; if it is not a Javascript language node, the exception interceptor of the Javascript engine intercepts and obtains The string; query whether there is a binary component corresponding to the string from the loading path of the binary component; create a binary component object corresponding to the string and encapsulate it as a Javascript object. This method enables flexible loading of binary components as required during the parsing and execution of Javascript scripts.
