Abstract

The gasification of used tires in the filtration combustion mode is studied using calcium-containing additives, both chemically inert and those capable of absorbing sulfur. It is found that during the gasification of compositions with an inert additive, 28, 29, and 43% of the sulfur contained in the initial material passes into the ash, resin and gaseous products, respectively. The introduction of marble crumb as an additive increases the proportion of sulfur passing into ash by a factor of 1.5 and reduces the yield of pyrolysis resins in comparison with an inert additive. In this case, the distribution of sulfur between the solid, liquid, and gaseous products of gasification is 40, 26, and 34%, respectively.

汽车轮胎气化产品中的硫分布

摘要

使用化学惰性和能够吸收硫的含钙添加剂研究了过滤燃烧模式下的旧轮胎的气化。已经发现，在用惰性添加剂气化组合物的过程中，原料中所含硫的28、29和43％分别进入灰分，树脂和气态产物。与惰性添加剂相比，大理石碎屑作为添加剂的引入使进入灰分的硫比例增加了1.5倍，并降低了热解树脂的收率。在这种情况下，硫在气化的固体，液体和气态产物之间的分布分别为40％，26％和34％。
