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： There is a system for producing high-purity hydrogen by reforming a hydrocarbon and/or an oxygen atom-containing hydrocarbon to form a reformed gas containing hydrogen and separating the hydrogen from said gas. The system includes a hydrocarbon source, a water source, an oxygen source, a vaporization chamber connecting with the hydrocarbon source, the water source and the oxygen source, and a reforming chamber provided with a catalyst for steam reforming and partial oxidation and a hydrogen-separating membrane. The reforming chamber is thermally connected with the vaporization chamber. A process for producing high-purity hydrogen includes heating a reforming chamber provided with a hydrogen-separating membrane, feeding, into the reforming chamber, hydrocarbon, steam and oxygen or air to give rise to steam reforming and partial oxidation therein to produce a reaction gas, and passing the reaction gas through the hydrogen-separating membrane to recover high-purity hydrogen. The heat possessed by the portion of the reaction gas not permeable into the hydrogen-separating membrane and the heat generated by the partial oxidation are utilized for the heating and reforming of the hydrocarbon, water and oxygen or air.

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.
