Abstract: The present invention aims to provide a method for producing auricular cartilage tissue having a sufficient thickness and mechanical strength, and auricular cartilage tissue produced by the method for producing auricular cartilage tissue. The present invention provides a method for producing auricular cartilage tissue, including the steps of: seeding auricular chondrocytes onto a non-woven fabric consisting of a bioabsorbable material having an average fiber diameter of 0.90 to 7.00 ?m; and forming a composite of the non-woven fabric seeded with the auricular chondrocytes and a mesh-like framework consisting of a non-bioabsorbable material, and shaping the composite.

Abstract: A process for producing ethylated benzene by a reaction of benzene with ethylene in the presence of a catalyst containing a zeolite .beta. by using a fixed-bed ascending-flow type reactor, which comprisesa) carrying out the reaction under conditions under which ethylene bubbles are present at the inlet of a catalyst layer when ethylene is fed upward from under the catalyst layer,b) recovering reaction products as a liquid from the upper part of the reactor and at the same time taking out a distillate composed mainly of unreacted benzene therefrom as vapor, andc) adjusting the temperature of the catalyst layer at its inlet to a temperature at least 50.degree. C. lower than the maximum attained temperature of the catalyst layer.
