...) which can provide three times the amount of isobutylene and isoamylene than conven- tional FCC and has been successful commercialized since 1995. For etherification of iso-olefins, a novel process is being developed based on solid acid catalyst instead of resin which enables regeneration, reduces...

... modes can predominantly produce either ethylene and propylene for petrochemicals or isobutylene and isoamylenes for ethers blending in RFG. 50 wt% of light olefins yield can be obtained by using heavy feedstocks, such as VGO and heavier. For maximum propylene operation mode, the propylene yield can...

... Abstract. Problems of pollution and energy supply have led in the past few years to the exploration of new fuel components, all over the world. Among these, the MTBE produced from isobutylene and methanol seems to be one of the most promising ones. The presently known practical production...

The inhibiting effect of unsaturated hydrocarbons on the decomposition of paraffins and the initiating...

... and isolated. A number of physical properties were measured, and the stability of the pure catalysts was studied. These aluminum catalysts were used to alkylate phenol with isobutylene. Rate of reaction and product distribution were determined for each catalyst. The efficiency of each was compared...

... Abstract Data on the gas phase reaction of isobutane and isobutylene in the presence of nuclear radiation are discussed. The temperature and pressure ranges studied were from 30°C to 350°C and from 0.5 to 14 atmospheres. Radiation absorbed doses (gamma radiation) varied from 1 x lo5 rad to 1 x...
