Abstract: "MéTODO PARA PROPORCIONAR UM REVESTIMENTO PROTETOR E INERTE EM AçO CARBONO E AçO INOXIDáVEL, COMPONENTE LIGADO NA SUPERFìCIE, TUBO REATOR RESISTENTE à COQUEIFICAçãO E CORROSãO, E, FORNO PARA A PRODUçãO DE ETILENO". Método para proteção de aço de baixo carbono e aço inoxidável, e particularmente aço inoxidável de alta temperatura, de coqueificação e corrosão em temperaturas elevadas em ambientes corrosivos, tais como durante a produção de etileno através de pirólise de hidrocarbonetos ou a redução de minérios de óxido, através de revestimento do aço inoxidável com uma cobertura de MCrAlXSiT em que M é níquel, cobalto, ferro ou uma mistura dos mesmos, X é ítrio, háfrio, zircónio, lantânio, escândio ou combinação dos mesmos, e T é tântalo, titânio, platina, paládio, rênio, molibdênio, tungstênio, nióbio, boro ou combinação dos mesmos. Uma composição em pó combinada para produzir uma liga desejada de superfície de MCrAlXSiT pode ser aplicada ao substrato. O revestimento de sobreposição e o substrato de aço inoxidável preferivelmente são tratados termicamente a cerca de 1000 a 1200<198>C durante cerca de 10 minutos ou por mais tempo efetivo para ligar metalurgicamente o revestimento de sobreposição ao substrato e formar uma microestrutura polifásica. A estrutura de liga na superfície é preferivelmente aluminizada através de depósito de uma camada de alumínio sobre isso e submetendo o revestimento resultante a oxidação em uma temperatura acima de cerca de 1000<198>C durante um tempo efetivo para formar uma camada de superfície de alumina. Também, o revestimento pode ser depositado sobre e metalurgicamente ligado ao substrato através de deposição do arco transferido de plasma de pó atomizado de MCrAlXT, prevenindo a necessidade por um tratamento térmico separado. Alternativamente, uma composição em pó combinada para produzir uma liga de MCrAlXT desejada pode ser aplicada ao substrato.

IPC: C08F259/04

Abstract: @ A polyvinyl chloride having high bulk density and enhanced plasticizer absorption is produced by suspension polymerization of vinyl chloride monomer and comonomers wherein the initial suspension of ingredients is formed such that the oil phase droplets formed in the suspension are compositionally equivalent with respect to initiator, and the level of suspending agent and agitation are chosen to substantially preclude agglomeration of resin particles throughout the reaction, thereby producing resin wherein the resin grain size distribution results directly from the oil phase droplet distribution created at the start of the reaction. Seed particles of resin are introduced to the reaction mixture priorto establishing the final particle distribution. The seed particles can be formed by polymerizing a monomer such as vinyl chloride and mixtures of vinyl chloride and copolymerizable monomers in the presence of a polymeric dispersing agent, and optionally a low boiling solvent which is a nonsolvent for the resin being produced. The result of the process of the invention is a polyvinyl chloride polymer or copolymer that has high bulk density and enhanced plasticizer absorption. A further benefit of the process is that resin deposition on the interior surfaces of the reactor is essentially eliminated.
