  • Patent number: 9493386
    Abstract: A method for supplying reaction gases in which at least a material to be oxidized and a gas containing molecular oxygen are mixed and the resultant mixture is supplied to a catalytic gas-phase oxidation reactor, characterized in that, a feed rate of the material to be oxidized and a feed rate of the gas containing molecular oxygen are adjusted so that when a composition of a gas at the inlet of the catalytic gas-phase oxidation reactor is changed from a composition A point [the concentration of the material to be oxidized: R(a), and the concentration of oxygen: O(a)] represented by plotting a concentration of the material to be oxidized and a concentration of oxygen in the gas at said inlet to a composition B point [R(b) and O(b)] [the composition A point and the composition B point are compositions outside an explosion range, and R(a)?R(b) and O(a)?O(b)], compositions on the way of the change from the composition A point to the composition B point fall outside the explosion range.

  • Patent number: 7641450
    Abstract: The present invention aims to provide a transfer method and a transfer facility for an easily polymerizable substance that limits standing retention of the easily polymerizable substance in the feed pump, etc., and the generation and adherence of solid matter such as polymer or precipitate that accompanies such retention, in a facility in which respective feed pumps are disposed at the plurality of passages that branch off at the easily polymerizable substance inflow side and converge at the easily polymerizable substance outflow side. In this easily polymerizable substance transfer method, in the case where one feed pump 13 operates and the other feed pump 14 is stopped, a portion of the easily polymerizable substance is fed to feed pump 14 and second passage 12 in a direction that is opposite to the direction of flow of the easily polymerizable substance when feed pump 14 is activated.

  • Patent number: 7419932
    Abstract: The method for preserving a catalyst of the present invention is characterized in that, in a process for continuously producing an objective product by a vapor phase oxidation reaction using a phosphorus-molybdenum-vanadium catalyst containing phosphorus, molybdenum and vanadium, the phosphorus-molybdenum-vanadium catalyst retained in a reactor is maintained under a condition of a water content of 30 mg or less per 1 g of catalyst dry weight, before the start of the reaction or during the stop of the reaction. By this, deterioration of the catalyst retained in the reactor can be simply prevented.

  • Patent number: 5166119
    Abstract: A method for preparing a multicomponent catalyst including molybdenum, bismuth, iron and cesium or thallium for producing methacrolein and methacrylic acid by the gas-phase catalytic oxidation of isobutylene or tert-butanol with molecular oxygen, wherein an aqueous nitric acid solution containing 0.01 to 0.36 mole of nitric acid per mole of ammonium molybdate, which is a material for the molybdenum component of the catalyst, and at least one material for the bismuth, iron, cesium and thallium components of the catalyst is added to an aqueous solution containing ammonium molybdate and materials for the remaining catalyst components, if any, to obtain a slurry which is then dried and calcined, provided that the nitric acid excludes nitric acid radicals contained in the materials containing the catalyst components. The amount of nitric acid used is controlled in a particular range, so that a highly active catalyst for gas-phase catalytic oxidation is obtained.

  • Patent number: 4670746
    Abstract: A keyless entry system can lock and unlock an automotive vehicle door, a trunk lid, a glove box and/or a steering column without an ignition key. The system comprises a transmitter producing a radio signal indicative of a preset unique code, and a controller receiving the radio signal and performing desired locking or unlocking operation when the code from the transmitter matches a preset code. A manual switch is provided to order the transmitter to transmit the code-indicative radio signal to the controller. The transmitter encloses a battery acting as a power source. Locking the transmitter in the vehicle is detected by detecting that the code signal level remains substantially unchanged for a given period of time after the vehicle is locked. In such cases, an alarm is produced to remind the driver to remove the transmitter from the vehicle cabin by operating the manual switch to open the door.
