    摘要： A connected body including a gas separator 10 and metallic members 21 and 22, each of which has a partly oxidized surface to be reliably connected with the gas separator. The gas separator includes a ceramic substrate 11 and a gas separation membrane 12 to be coated onto substrate 11. The substrate 11 is porous so that a gas molecule can pass therethrough, and gas separation membrane 12 is connected with metallic members 21 and 22 by a glass 15 having a thermal expansion coefficient of 5.0-8.0.times.10.sup.-6 /.degree.C. Glass 15 contacts with metal supporters 21 and 22 with a contact angle of 90.degree. or less. The connected body of a gas separator and metallic supporters and an apparatus for separating hydrogen gas from a mixed gas display excellent durability and are free from leakage at the joints during the separation of hydrogen gas at high temperatures and under high pressure.

    摘要： A method for separating p-xylene by separating and recovering only p-xylene from a p-xylene-containing raw material mixture under high-temperature and high-pressure conditions using a zeolite membrane as a separating membrane is provided. The p-xylene partial pressure at the raw material side of the separating membrane is kept at a sufficiently high pressure and the p-xylene partial pressure at the recovery side of the separating membrane is controlled at a pressure which is not higher than the inflection point of p-xylene adsorption curve. This method for separating p-xylene using a zeolite membrane as a separating membrane can secure a sufficient p-xylene permeation amount and has industrial applicability.

    摘要： A gas separator is here disclosed in which a metal for separating a gas is filled into pores opened on the surface of a porous substrate to close them. The thus constituted gas separator can prevent a material gas from leaking into a purified gas. A method for preparing the gas separator is also disclosed which comprises an activation step of immersing the porous substrate having a pair of surfaces in a solution containing an activated metal, while a pressure difference is set between the pair of surfaces, and a chemical plating step of filling the metal for separating the gas into the pores opened on the surface of the porous substrate to close these pores by chemical plating.

    摘要： An NOx sensor has the sensor element made of an oxide, the resistance of which is varied in response to an NOx component in a gas to be measured, and a measuring portion for measuring a resistance variation of the sensor element and for detecting an NOx concentration in the gas to be measured. A catalyst is arranged at an upstream side of a flow of the gas to be measured with respect reach to the sensor element, which makes a partial pressure ratio of NO/NO.sub.2 reach to an equilibrium state and removes a CO component from the gas to be measured. A heater for adjusting a temperature is arranged at a position close to the sensor element, which maintains temperatures of the sensor element and the catalyst constant. An O.sub.2 sensor is arranged at a position close to the sensor element so that the measuring portion can detect accurately the concentration of Nox in the measurement gas by reference to the resistance of the sensor element.
