Dehydrogenation of isobutane to isobutene process design
Abstract：Isobutane catalytic dehydrogenation technology is one of the main way to solve insufficient isobutylene.It is the key to the C4 comprehensive utilization to be concerned by the all over the word. C4 resources are rich in our country, while isobutylene is currently one of the scarce resources in our country, with isobutylene as resources of fine chemical industry is developing rapidly, demand is growing rapidly, and isobutane catalytic dehydrogenation isobutylene is one of the main ways to solve the shortage of isobutylene. At present, the domestic many institutions of higher learning are for isobutane dehydrogenation catalyst for laboratory research, foreign representative process mainly include: mobile bed Oleflex UOP process and Lummus company Catofin fixed bed process. Oleflex process using load platinum alumina catalyst, the catalyst continuous regeneration process for moving bed of proprietary UOP; Catofin process using chrome oxide catalyst, process with multiple reactor, catalyst regeneration to switch. This design in accord with national conditions, advanced technology and easy, the principle of economy, environmental protection, in catalytic cracking of C4 isobutane as raw material, with Cr2O3/Al2O3 catalyst, using fixed bed reactor, and the catalytic dehydrogenation of isobutane processes for material balance and heat balance, on the part of the equipment design and selection, the resulting isobutylene products subject to the technological requirements.
Key words： catalytic dehydrogenation；isobutylene；material balance；heat balance；equipment selection
