Abstract
METHOD FOR PRODUCING ISOBUTYLENE FROM ISOBUTANOL : The purpose of the present invention is to provide a method that can produce, with high yield or high selectivity isobutylene by means of isobutanol dehydration-reaction. An isobutylene production method of a first embodiment of the present invention is a method for producing isobutylene by means of isobutanol dehydration-reaction, wherein isobutanol is reacted using a catalyst for which the BET specific surface area is within the range of 60m 2/g-175m 2/g, and the reaction is carried out under a reaction pressure of 50kPa-750kPa as the absolute pressure. An isobutylene production method of a second embodiment of the present invention includes: using a catalyst which is filled into a reaction chamber and for which the particle diameters of at least 90 mass% of the catalyst are within the range of 700 µm - 1000 µm; setting the isobutanol concentration within a supplied reaction gas to 30vol% -85vol%; setting the weight hourly velocity (WHSV) of the isobutanol to 0.175h -1~20h -1; and reacting isobutanol under a reaction pressure of 50kPa-750kPa as the absolute pressure.
