Abstract: A device generating hydrogen from a hydrocarbon, oxygen and water. The reaction is carried out at high temperature. The device includes a first substantially cylindrical zone surrounding the reaction chamber circulates water vapour and hydrocarbon, excluding the reaction products, the zone being separated from the reaction chamber to recover heat lost by the reaction chamber, to preheat the mixture circulating in the first zone. The reagent(s) are in contact with the walls of said first zone to exchange produce heat. A substantially cylindrical second zone surrounds the first zone and circulates water to be vaporized, the water is in contact with the walls of said second zone. The first and second zones are separated such that water circulating in the second zone is preheated by heat of the first zone where the water of the second zone is mixed with the hydrocarbon and introduced into the first zone.

Abstract: An apparatus for continuously producing polyisocyanate is provided for quickly contacting polyamine and carbonyl chloride in order to suppress an undesirable reaction between polyamine and polyisocyanate so that a by-product can be reduced and the yield of polyisocyanate can be improved. In a circulatory line 7, a material-mixing portion 8, a high-shear pump 3, a reactor 4, a liquid-feeding pump 5 and a cooler 6 are interposed in series along the direction of the flow of a reaction solution, thereby forming a closed line. In this apparatus 1, after polyamine and carbonyl chloride are supplied in the material-mixing portion 8, the reaction solution is sheared by the high-shear pump 3 in a state where the contact of the polyamine with the reaction solution is minimized. Thus, the formation of a urea compound as a by-product can be suppressed and the yield of polyisocyanate can be improved.
