    • The invention provides a sulphur pellet comprising at least one H2S-suppressant, comprising in the range of from 60 to 100 wt % elemental sulphur, based on the total weight of the pellet. The invention further provides a process for the manufacture of sulphur pellets comprising at least one H2S-suppressant, comprising the steps of: (a) mixing elemental sulphur, one or more H2S-suppressants and optionally a filler in a mixing unit to obtain a mixture; (b) shaping and/or palletizing the mixture obtained in step (a) in a palletizing unit to obtain H2S-suppressant-comprising sulphur pellets. The invention further provides a process for the manufacture of a sulphur-comprising asphalt paving mixture comprising the steps of: (i) preheating bitumen at a temperature of between 140 and 180° C.; (ii) preheating aggregate at a temperature of between 140 and 180° C.; (iii) mixing the hot bitumen with the hot aggregate in a mixing unit, wherein sulphur pellets comprising H2S-suppressant according to the invention are added in at least one of the steps (i), (ii) or (iii). The invention also provides the use of a sulphur-comprising asphalt paving mixture comprising H2S-suppressant in the paving of roads.
    • 本发明提供了包含至少一种H2S抑制剂的硫粒料,其包含基于颗粒总重量的60至100重量%的元素硫。 本发明还提供了一种制备包含至少一种H 2 S抑制剂的硫粒料的方法,包括以下步骤:(a)在混合单元中将元素硫,一种或多种H 2 S抑制剂和任选的填料混合以获得混合物 ; (b)将在步骤(a)中获得的混合物成型和/或码垛在码垛单元中以获得含硫化氢的硫粒子。 本发明还提供了一种制备含硫沥青铺路混合物的方法,包括以下步骤:(i)在140-180℃的温度下预热沥青; (ii)在140-180℃的温度下预热骨料; (iii)将热沥青与热骨料混合在混合单元中,其中包含根据本发明的H 2 S抑制剂的硫粒料加入到步骤(i),(ii)或(iii)中的至少一个中。 本发明还提供了在道路铺路中使用包含H2S抑制剂的含硫沥青铺路混合物的用途。
