Integration of molecular redistribution and hydroisomerization processes for the production of paraffinic base oil

Wed, 3 Jun 2009 14:50:25 -0700

The process as described herein produces a moderately aromatic isoparaffinic base oil from a distillate range product. This process comprises: (a) providing a distillate range paraffin feed comprising paraffins and cycloparaffins; (b) mildly reforming the distillate range paraffin feed to convert at least a portion of the cycloparaffins to alkylaromatics...

Method and device for manufacturing at least one low olefin from an oxygenate-containing first reaction mixture (11) through conversion by a catalyst (20) to an olefin and paraffin-containing second reaction mixture (21) where the second reaction mixture (21) is flowed through a separation system (300), in which one at least...

Method for preparation of ethylene and propylene by catalytic cracking using a fluid-bed catalyst

Wed, 3 Jun 2009 14:50:25 -0700

A method for preparation of ethylene and propylene by catalytic cracking using a fluid-bed catalyst. The main technical problems to be solved are a relatively high reaction temperature, and low activities and poor selectivities of the catalyst at a low temperature, during the reaction for preparing ethylene and propylene by...
