摘要： It has been discovered that the efficiency of asphalt blow stills (reactor columns) can be improved by filling the blow still with various types of packing material, such as metal or glass spheres (or other rigid materials). The packing material acts to reduce air bubble size and improve the dispersion of the air bubbles throughout the asphalt. This increases the total surface area per unit volume of the air bubbles and promotes a faster processing time. The packing material also increases the contact time between the air bubbles and the asphalt which further results in improved efficiency and reduced blow times. This is beneficial because faster processing times can be achieved resulting in more efficient use of equipment, higher levels of productivity, lower energy requirements, cost savings, reduced blow loss, and reduced thermal history to which the asphalt is exposed.

摘要： An apparatus for controlled blowing of asphalt comprises a stator block, a rotor, a motor, a gap, a gas conduit, and a porous plug. The rotor resides within a cylindrical interior chamber of the stator block. When engaged, the motor causes the rotor to rotate about the longitudinal axis of the rotor. A porous plug is within a gas conduit at an opening into the interior chamber of the stator block. The porous plug allows the gas to pass from the gas conduit into the gap as tiny bubbles. In this way, the asphalt continuously enters the apparatus at the inlet end of the interior chamber, passes through a gap between the interior chamber and the rotor where gas is blown through the porous plug and into the asphalt while the motor rotates the rotor, and exits the apparatus at the outlet end of the interior chamber as blown asphalt.

摘要： Methods are provided for upgrading asphaltene-depleted crude fractions. The asphaltene-depleted crude fractions are upgraded by oxidizing the crude fractions by air blowing. Upgrading an asphaltene-depleted crude fraction can allow more valuable grades of asphalt to be formed from the crude fraction. Alternatively, upgrading an asphaltene-depleted crude fraction can allow for incorporation of a greater percentage of such a crude fraction in a blend of crudes that are used for making a desired grade of asphalt.
