    摘要： The invention relates to an apparatus and a process for spraying liquids and producing very fine mist, where the apparatus comprises a needle injector, a liquid supply (5) and a gas supply (4). The needle injector comprises at least one capillary line (1) and at least one outer tube (8), where the capillary line (1) is arranged in the interior space of the outer tube (2) and the needle injector is characterized in that the internal diameter of the capillary line is in the range of 2-1000 µm, preferably in the range of 4-300 µm, more preferably in the range of 5-250 µm. The capillary line is in active communication with a gas supply (4) and the outer tube (2) is in active communication with a liquid supply (5). A spray mist which comprises the liquid in the form of very finely dispersed droplets of 10-20 µm and has a low flow velocity is produced by means of the process of the invention. The properties of the spray mist can be controlled very well via the configuration of the apparatus and the experimental parameters. A preferred field of use of the apparatus is the controlled introduction of spray mists into reaction apparatuses for the study of catalysts or in impregnation apparatuses for the deposition of liquids.
