WitrynaThe catalytic cracking of dodecane and straight run heavy naphtha (boiling point of 157–202 °C) was conducted at atmospheric pressure in a packed bed reactor. Firstly, N 2 was fed as a carrier gas at a constant flow rate of 30 ml min −1 , and the reactor temperature was raised to 350 °C. WitrynaThe catalytic cracking of naphtha was increased as the moderate catalytic acidity strength increased and the 50% Zr–Ti oxide catalyst delivered higher conversion between 85–95% with olefin yield around 55–60%. The surface acidity of the Zr–Ti …

Asian refiners to raise gasoline output, cut diesel to ease oversupply

WitrynaTraditionally, propylene has been obtained as a byproduct from steam cracking naphtha and gas oils to produce 
ethylene, and from gasoline-producing refinery fluid … WitrynaA catalytic process that produces light olefins from naphtha was developed to improve the yield of the conventional steam cracker. In laboratory-scale tests, a newly … Witryna11 sty 2016 · Since the yield of light olefins (C 2 H 4 + C 3 H 6) from catalytic naphtha cracking is a good indicator of the cracking activity of ZSM-5 [28, 29], the yields of light olefins for three different types of ZSM-5 were compared before and after steaming under the mild condition of 500 °C for 6 h in 100 % steam. mocpa membership
