Abstract

The invention discloses a Ru-Pt-Ni catalyst used for synthesizing vinyl chloride by hydrochlorinating acetylene. The Ru-Pt-Ni catalyst comprises an inert porous carrier, a ruthenium salt, a nickel salt and a platinum salt, wherein the ruthenium salt, the nickel salt and the platinum salt are carried on the inert porous carrier, the weight of the Ru is 0.01%-5% of the weight of the Ru-Pt-Ni catalyst, and the mole ratio of the Ru, the Pt and the Ni is 1:0.1-10:0.1-10. The Ru-Pt-Ni catalyst is advantageous in that: by using the Ru-Pt-Ni catalyst for synthesizing the vinyl chloride by hydrochlorinating acetylene, the reaction temperature can be decreased to be lower than 180 DEG C, the selectivity of a reaction product is good, byproducts are little, the reaction activity is high, the conversion rate of acetylene exceeds 99% and the selectivity of the vinyl chloride reaches 99.9%; the catalyst is high in strength and long in service lifetime; and regeneration of the catalyst after an reaction is simple. A preparation method is simple in technology and is easy to operate.

Description

technical field [0001] The invention relates to a mercury-free catalyst for synthesizing vinyl chloride by utilizing acetylene. Background technique [0002] With the development of the national economy and the improvement of people's living standards, the demand for polyvinyl chloride is increasing. At present, the mercury-containing catalyst used in the production of vinyl chloride by the calcium carbide method will produce "mercury pollution" on the one hand, and face the problem of lack of mercury resources on the other hand. [0003] At present, the research and development of mercury-free catalysts for acetylene hydrochlorination to vinyl chloride are faced with the problems of catalyst activity and life. Most of the currently used catalysts have poor activity. Although some have good activity, the life of the catalyst is short and cannot be industrialized. For this reason, the current research hopes to improve the performance of the catalyst through the method of mu...
