    摘要: A process for treating an alkylation feedstock comprising olefins, n-alkanes, iso-alkanes, and impurities including one or more of butadiene, oxygenates, nitrogen-containing compounds, and sulfur-containing compounds, the process including: contacting an alkylation feedstock containing at least one of oxygenates and nitrogen-containing compounds with water to produce a hydrocarbon fraction having a reduced concentration of the at least one of oxygenates and nitrogen-containing compounds and an aqueous fraction comprising at least a portion of the at least one of oxygenates and nitrogen-containing compounds; separating water from the hydrocarbon fraction having a reduced concentration to produce a hydrocarbon fraction having a reduced water content; contacting the hydrocarbon fraction having a reduced water content with an oligomerization catalyst in a first oligomerization reaction zone under oligomerization conditions to react at least a portion of the olefins to form a reactor effluent comprising olefin oligomers; and feeding at least a portion of the reactor effluent to an alkylation unit.

    摘要: A polyolefin wax for a coating material which includes an ethylene (co)polymer having a number-average molecular weight within the range of from 400 to 5000 as measured by gel permeation chromatography. The polyolefin wax has a volume average particle diameter in the range of from 0.3 μm to 20 μm wherein the relation between a particle diameter a (μm), in which the weight ratio of the large particle diameter side in weight particle-size distribution is 10%, and a particle diameter b (μm), in which the weight ratio of the small particle diameter side in weight particle size distribution is 10%, satisfies the a/b≦4 and the relation between the crystallization temperature Tc (° C.), measured at a cooling rate of 2° C./min) as measured by differential scanning calorimetry (DSC) and the density D (kg/m3) as measured by the density gradient tube method satisfies the equation 0.501×D−366≧Tc. A printing ink composition the polyolefin wax and an liquid dispersion containing particles of an ethylene polymer composition are also set forth.
