Conclusions 1. A new method of deasphalting reduced crudes with a moving bed of adsorbent has been investigated; this process gives efficient separation of the basic chemical groups and a high yield of valuable oil components. 2. The primary deasphalted oils obtained from a series of Volgograd, Perm', Bulgarian and Zhirnovsk crudes are thoroughly deresined products (1.5–3% resins) with high viscosities (30–45 cSt at 100°C) and carbon residues (2–4%), as a result of increased recovery of high-viscosity paraffinic, naphthenic, and aromatic hydrocarbons and compounds from the reduced crudes. 3. When the adsorption-deasphalted oils are further treated with a moving bed of adsorbent, light-colored deresined residual oils can be obtained in various viscosity levels (from aviation oils up to heavy bright stocks).
