Abstract: A side airbag device for a motor vehicle includes an airbag, in which, in the event of an impact, gas is introduced by a gas generator of the side airbag device. The airbag includes drain valve for removing the gas immediately after the impact. The device also includes an electronic computing unit and a further drain valve and/or a further gas generator. A passenger of the motor vehicle is detected by a detection unit. The device is filled with the gas in the event of the impact to protect this passenger. The electronic computing unit is configured, depending on the detected passenger, to determine a gas pressure in the airbag by actuation of the further drain valve or the further gas generator before the impact and to adapt the gas pressure to the passengers during the impact.

Abstract: The present invention relates to a process and a plant for producing sulfuric acid, in which a starting gas containing sulfur dioxide at least partly reacts with molecular oxygen in at least one contact with at least one contact stage to form sulfur trioxide, and in which the sulfur-trioxide-containing gas produced is introduced into an absorber and converted there to sulfuric acid. To achieve that only small gas volumes must be supplied to the first contact stage, based on the amount of sulfur dioxide used, with at least the same capacity of the plant and by using conventional catalysts, it is proposed in accordance with the invention to supply to the first contact stage a contact gas with a sulfur dioxide content of more than 16 vol-% and with a volumetric ratio of sulfur dioxide to oxygen of more than 2.67:1.
