Abstract: The novel feature in prodn. of acetylene and synthesis gas by partial oxidn. of hydrocarbons with O2 where the starting gases are separately pre-heated, intensively mixed, reacted during passage through a burner block and finally rapidly cooled is that the through channels (6) in the burner block have their inlets covered by perforated (13) discs (14). The appts., comprising a mixing chamber, the block and a quencher, is also claimed as novel.

Abstract: A reaction system for prodn. of polyphenylene-ethers comprising a propulsive jet reactor, a heat exchanger and a circulation pump, characterised in that instead of a conventional cooled tube heat exchanger, a heat exchanger with circulating eddy layer is used. ADVANTAGE - The use of a heat exchanger with circulating eddy layer reduces the progressive increases in pressure loss over the heat exchanger which occurs with conventional cooled tube heat exchangers due to deposition of high mol. wt. PPE fractions on the tube walls, and thus allows the system to be operated for extended periods without maintenance.
