Process to remove polluting vehicles that contain one or more of the nitrogen, oxygen, nitrogen and sulfur atoms sulfur oxygen non homogeneous hydrocarbon Altyrat hydrocarbon

摘要

Abstract: the present invention relates to a process to remove contaminated compounds which contain one or more sulfur atoms or nitrogen nitrogen sulfur and / or non oxygen oxygen one or more of T Hydrocarbon, rat. Hydrocarbon be as adsorbed polluting vehicles include: adsorption step is described by adsorption adsorbed material consisting essentially of silica gel, silica gel and I Lmmkn may be modified with one or more metalsSelected from elements of groups VIII, VIb, VB, IVB, IIb, Ib, or tin tin or bismuth, or lead lead, bismuth the step is carried out Nddrjt temperature ranging between February and 150 Mywytwtht Z Cover of between I and atmospheric pressure; a step of washing with an optional polar solvents, hydrocarbon polar solvents hydrocarbons; and re configured to remove material Amtzazha adsorbed by u The thermal treatment in the inert gas flowInert gas and is carried out at a temperature ranging from 100 to 200 degrees Celsius.
