Using Aspen Plus simulation software to simulate the hydrogen solubility of white oil raw materials, and calculate the de-aromatic hydrogen consumption. The liquid hydrogenation technology of white oil was studied by using 100mL uplink liquid hydrogenation evaluation device. The research results show that the ultraviolet absorbance of the liquid phase hydrogenation product is no more than 0.1, and saybolt color, copper plate corrosion, readily carbonizable substance can meet the quality requirements under the conditions of 230℃, 17 Mpa and LHSV 0.5 h-1. 2000 hours liquid phase hydrogenation test shows the stability of product quality which meets the food grade standard, and the liquid phase hydrogenation technology is feasible.

In the presented review the results of studies devoted to the selective hydrogenation of acetylene to ethylene over bimetallic palladium-containing catalysts are systematized. General regularities and peculiarities of the catalysts action in gas-phase hydrogenation of traces of acetylene in the acetylene-ethylene mixture obtained by pyrolysis of petroleum raw materials, as well as in the process of liquid-phase hydrogenation of mixtures enriched with acetylene and hydrogen are analyzed. The advantages of obtaining ethylene by hydrogenation of acetylene in the liquid phase are shown and ways of increasing the selectivity of this process are considered.
