Embodiment

[0076] Experiments were carried out using the reactor system as described above (the examples illustrate according to figure 1 ).

[0077] The reactor system consisted of 120 tubes for the evaporation part and the same number of tubes for the thermal decomposition part. For the tubular evaporator and pyrolysis elements used, ST35 precision tube elements according to DIN2391 were used. The internal diameter was varied between 0.5 and 13 mm and the wall thickness used varied between 0.1 and 1.5 mm. The thermal decomposition part is directly connected to the evaporator part.

[0078] The tubes of the evaporator and thermal decomposer can be assembled into bundles according to predetermined pitches and welded or extruded on the respective tube bundle ends using top / end plates. A plurality of intermediate plates are interposed between the top / end plates.

[0079] Both reactor sections fit in induction coils which are specially adapted to the evaporator body and the pyrolysis bo...

Abstract

The present invention relates to methods and apparatus for the pyrolysis or pyrolysis of fluids or fluidized starting materials under negative pressure in a multi-tubular reactor comprising a plurality of reactor tubes capable of being heated, wherein in one The starting material is supplied to the multi-tubular reactor at the end by at least one supply line, wherein the supply line has a plurality of pressure reduction units which allow independent reaction after introducing the starting material into the multi-tubular reactor Positive pressure before the reactor tubes and negative pressure inside the reactor tubes associated therewith, wherein the pressure reduction unit controls the substantially equal inflow of starting material into separate reactor tubes, and the reactor tubes are in at least one main section is heated to the decomposition temperature of the starting material, whereby the starting material is pyrolyzed or thermally decomposed and a pyrolysis product or pyrolysis product is obtained.

Description

technical field [0001] The present invention relates to methods and devices for carrying out chemical reactions under negative pressure in heated reactors. Background technique [0002] Publication WO 2010 / 083978 A2 describes a tube bundle reactor consisting of a plurality of reactor tubes which can be heated. The reactor has a homogenization plate with holes or channels for storing the reaction mixture before entering the tube bundle. Each hole or each channel has the same size. [0003] EP 363 066 B1 describes an inductively heatable reactor for liquid-phase reaction processes, in particular for the high-temperature pyrolysis of chlorodifluoromethane, which consists of a block of material with a plurality of reactor tubes, Wherein said block of material can be heated inductively. [0004] DE 27 12 728 A1 describes a tubular reactor for heating gases or vapours, in which these gases or vapours are passed through a filling of electrical conductors heated by electromagneti...
