Abstract: The present invention provides a method for preparing acetic acid by carbonylation of methanol, which comprises: passing a raw material containing methanol, carbon monoxide and water through a reaction region loaded with a catalyst containing an acidic molecular sieve with an adsorbed organic amine, and carrying out a reaction under the following conditions to prepare acetic acid. The method in the present invention offers high acetic acid selectivity and good catalyst stability. The catalyst in the present invention does not contain noble metals such as rhodium or iridium, and does not need additional agent containing iodine, and thus does not generate a strong corrosive hydroiodic acid and the like.

Abstract: A reactor system for dehydrogenation of ethylbenzene to styrene in a given temperature range T upon bringing a reactant stream including ethylbenzene into contact with a catalytic mixture. The reactor system includes a reactor unit arranged to accommodate the catalytic mixture, the catalytic mixture including catalyst particles in intimate contact with a ferromagnetic material, where the catalyst particles are arranged to catalyze the dehydrogenation of ethylbenzene to styrene. The reactor system moreover includes an induction coil arranged to be powered by a power source supplying alternating current and being positioned so as to generate an alternating magnetic field within the reactor unit upon energization by the power source, whereby the catalytic mixture is heated to a temperature within the temperature range T by means of the alternating magnetic field. Also, a catalytic mixture and a method of dehydrogenating ethylbenzene to styrene.

Abstract: An object of the present invention is to provide an exhaust gas purification catalyst which can exhibit sufficient purification performance even under a high Ga condition. The present invention relates to an exhaust gas purification catalyst comprising a substrate and a catalyst coating layer formed on the substrate, wherein the catalyst coating layer comprises catalyst particles, the catalyst coating layer having an upstream region extending by 40 to 60% of the entire length of the substrate from an upstream end of the catalyst in the direction of an exhaust gas flow and a downstream region corresponding to the remainder portion of the catalyst coating layer, the composition of the catalyst particle of the upstream region being different from that of the downstream region. The downstream region in the direction of an exhaust gas flow has a structure where a void is included in a large number, and furthermore high-aspect-ratio pores having an aspect ratio of 5 or more account for a certain percentage or more of the whole volume of voids. Thus, the exhaust gas purification catalyst exhibits enhanced purification performance.
