    摘要： In a hydrogen sensor (10a, 10b, 10c, 10d), a thin film layer (12) is formed over a substrate (11) and a buffer layer (13) is formed over the thin film layer (12). Further, over the buffer layer (13) is formed a catalyst layer (14) which, by being contacted by hydrogen gas, hydrogenates the thin film layer (12), thereby changing optical reflectance of the thin film layer (12). A constituent of the thin film layer (12) diffusing into the catalyst layer (14) combines with a constituent that has diffused from the buffer layer (13) into the catalyst layer (14), so that oxidation of the catalyst film layer (14) is prevented. Consequently, oxidation of the catalyst layer (14), etc. caused by repetition of hydrogenation of the thin film layer (12) is prevented, and therefore, decrease in hydrogen detection sensitivity of the hydrogen sensor (10a, 10b, 10c, 10d) is restrained.

    摘要： The present invention pertains to a process for testing FCC catalysts on a small scale wherein: a) the feed to be cracked is heated to a temperature between 50 and 500° C., b) the heated feed is injected into a riser reactor containing the FCC catalyst to be tested having a temperature between 500 and 800° C., the injection time being less than 2 seconds, c) the feed is contacted with the FCC catalyst under fluidized conditions for a contact time of less than 8 seconds, and d) the feed is stripped from the FCC catalyst and the properties of the product are analyzed. The invention also comprises the apparatus employed to carry out the process. With the process of the invention the mass transfer and diffusion limitations of commercial FCC units are properly simulated.
