Is there a route for post-treating gasoline with minimal octane loss?

For the post-treatment of FCC gasoline, fixed-bed HDT is by far the most trusted solution because of its low capex, its ease of operation, and its flexibility.

Hydrogen consumption is higher than we would like in our raw diesel hydrotreater. Can we lower it without loss of throughput?

Hydrogen consumption in a hydrotreater comes from hydrotreatment reactions but also from losses within the process.

What type of catalyst do we need for low pressure hydrotreating of middle distillates?

When it comes to selecting the right catalyst for the hydrotreatment of a middle distillates fraction at low pressure, a distinction has to be made between light (kerosene) and heavy (diesel) cuts.
