Problems solved by technology

However, the active metal compound and aluminum hydroxide dry rubber powder or alumina powder are directly mixed and formed by kneading method. This method has problems such as uneven mixing of crystal particles and deterioration of catalyst strength. It is not easy to combine with each other to form a specific skeleton structure
[0014] Due to the production of C5 petroleum resin raw materials and polymerization process, etc., there are unsaturated bonds and large steric hindrance on it, and it also contains halides and hydrogen sulfide. Some synthesis processes also have gel formation, which makes hydrogenation of C5 petroleum resin difficult. Big

Abstract

The invention provides a carbon-5 petroleum resin hydrogenation method which comprises the steps: dissolving carbon-5 petroleum resin in an organic solvent in a mixer; sending into a fixed bed hydrogenation reactor after preheating; filling the reactor with a nickel-copper series hydrogenation catalyst; sending a hydrogenated material to a stripping tower; recycling the organic solvent after the organic solvent extracted out from the upper part is refined; obtaining carbon-5 hydrogenated petroleum resin at the bottom of the stripping tower. When the catalyst prepared by the method disclosed bythe invention and a carrier having specific crystal form and containing nickel is used, a reactive metal utilization rate can be greatly improved, and catalyst preparation difficulty is reduced; meanwhile, chosen active ingredients are added to achieve a synergistic effect, and the carbon-5 hydrogenated petroleum resin with a low bromine number and good chromaticity and stability is prepared.

Description

technical field [0001] The invention relates to a method for hydrogenating C5 petroleum resin, in particular to a method for hydrogenating C5 petroleum resin catalyzed by a Ni-Cu series catalyst. Background technique [0002] The carbon five hydrocarbons mainly come from the by-product carbon five fractions in the high-temperature cracking of petroleum hydrocarbons to ethylene (referred to as cracked carbon five) and catalytic cracking gasoline in petroleum refineries. As of 2016, China's domestic ethylene production reached 17.812 million tons. If liquid hydrocarbons (such as naphtha and light diesel oil) are used as cracking raw materials, the cracking C5 yield can reach 14% to 20% of the ethylene production. [0003] The utilization of carbon five hydrocarbons includes two aspects of fuel and chemical industry. For now, C5 hydrocarbons are basically used as fuel, and the chemical utilization rate is only about 10%. In terms of cracking C5 utilization, Shanghai Petrochem...
