  • Economically recover olefins from FCC offgases (Journal

    This ethylene yield is anywhere from 0.7 to 1.1 of the FCC feed as opposed to 26 to 36 for naphtha or gas oil cracking in conventional olefin plants. Due to high FCC unit feedrates (typically 25 000 to 85 000 bpsd for most North American refineries) even with a low ethylene yield the olefins production can be significant.

  • Towards Solar Methanol Past Present and Future

    The original BASF process involved the gas‐phase heterogeneous catalytic conversion of syngas to MeOH at high temperatures and pressures of 360–380 °C and 25–30 MPa respectively using a chromium and manganese oxide–based catalyst. 10 This process afforded a relatively low yield of just 10 mol MeOH. 10 Today the preferred catalysts
