Abstract
In hydrodesulfurization of petroleum resids with preliminary deasphalting with propane, propane–butane, and naphtha, resins and asphaltenes of different degrees of concentration are obtained in addition to the basic products [1]. These resources are important because of processing of heavy, resinous, and medium-sulfur crude oils. They are used as feedstock for production of products used in different branches of the national economy, which increases the profitability of crude oil refining as a whole [1, 2]. For example, gaseous carbons, which have higher selectivity than industrial adsorbents, can be produced with cracked tar [3].
