Abstract

The invnetion discloses a attapulgite gasoline desulfurizer composed by attapulgite clay, iorn oxide, alumina, copper oxide and zinc oxide. The preparing method includes steps: mixing dosages of the attapulgite gasoline desulfurizer, adding nitrate acid for acid-curing, extruding and airing, crushing and sieving, baking and packaging as products. After gasoline contacted sufficiently with the attapulgite gasoline desulfurizer, sulfuret of gasoline absorbed on particles thereof to reduce sulfuret content of gasoline; iorn oxide, alumina, copper oxide and zinc oxide is generated as nitrate after nitrate acid-curing and created chemical reaction with sulfuret of gasoline to further reduce sulfuret content of gasoline. The attapulgite gasoline desulfurizer is suit for desulfuration process of gasoline, diesel oil and aviation kerosene.

Description

Technical field: [0001] The invention relates to a desulfurizer, in particular to an attapulgite gasoline desulfurizer. Background technique: [0002] As people pay more and more attention to environmental protection, the deep removal of sulfur compounds in gasoline has been put on the agenda, because the existence of various sulfur compounds in gasoline will cause many hazards, such as making gasoline produce an unpleasant smell, reducing gasoline quality, corrode the engine, poison the downstream process catalyst, cause container swelling, etc., especially cause environmental pollution, so desulfurization treatment is necessary. [0003] There are many kinds of sulfides in gasoline. Active sulfides include hydrogen sulfide, elemental sulfur, mercaptan, etc., which have a strong corrosive effect on metal equipment; The equipment has no corrosive sulfides, and some inactive sulfides will become active sulfides after thermal decomposition. [0004] There are many methods fo...
