摘要： A porous solid acid catalyst for producing light olefins is prepared through pillaring and a solid state reaction of a raw material mixture. The catalyst is made of a porous material having a crystalline structure that is different from that of the raw material mixture. The catalyst exhibits excellent catalytic activity (i.e., conversion and selectivity) in the production of light olefins from hydrocarbon feeds such as full range naphthas.

摘要： Particles in a glass substrate are measured by executing following steps: sequentially conveying a plurality of glass substrates; scanning with a camera a unit area of a glass substrate in a direction of a travel path of the glass substrate and storing particle information thereof; shifting the camera to a position corresponding to a next unit area for a succeeding glass substrate; storing information on the particles in the unit area of the succeeding glass substrate obtained by scanning the glass substrate; estimating whether a sum of the respective scanned unit areas is within an allowed limit of an area of a glass substrate; and returning to the third step if an answer from the fifth step is “No” or storing information on the particles in the entire glass substrate if the answer is “Yes”.

摘要： A method for and an apparatus for controlling and optimizing a xylene isomer separation and isomerization process, in which near infrared light of a wavelength ranging from 1,100 nm to 2,500 nm is transmitted through samples obtained at different stages of the process from raw materials flowing in the process by use of an analyzer system using optical fibers, thereby simultaneously measuring, in an on-line manner, xylene isomers and aromatic hydrocarbons containing 6 to 9 carbon atoms from those samples. Accordingly, it is possible to monitor the entire operation state of the process within 15 minutes in an on-line manner. Conventionally, 2 to 3 days are taken for the same monitoring.
