A method of upgrading hydrocarbons for a predetermined period of time. The method may include determining an amount of one or more contaminant-containing components to be present in the pyrolysis effluent based, at least in part, on a composition of a hydrocarbon feed to be steam cracked, a temperature at which the hydrocarbon feed is to be heated during steam cracking, a residence time at which the hydrocarbon feed is to be heated during steam cracking, or a combination thereof. In some examples, the method may also include performing one or more steps to allow the hydrocarbon feed to steam crack at least as long as a predetermined period of time, such as controlling process conditions within one or more separation stages to facilitate certain product compositions and/or introducing a predetermined amount of one or more materials into various locations of the process, or any combination thereof. 提质烃持续预定时间段的方法。方法可包括至少部分基于以下确定将在热解流出物中存在的一种或多种含污染物成分的量：待蒸汽裂化的烃进料的组成，将在蒸汽裂化期间加热烃进料的温度，将在蒸汽裂化期间在该温度下加热烃进料的停留时间，或它们的组合
