Title: Jolinde Machteld Van De Graaf: Innovator in Hydrocarbon Processing

Introduction

Jolinde Machteld Van De Graaf is a prominent inventor based in Amsterdam, Netherlands. She has made significant contributions to the field of hydrocarbon processing, holding a total of 3 patents. Her innovative approaches focus on improving the efficiency and effectiveness of processes related to paraffinic feedstocks and the removal of sulfur compounds from hydrocarbon streams.

Latest Patents

One of her latest patents is a process for the conversion of paraffinic feedstock. This invention provides a method for converting feedstock that contains a high percentage of paraffins while minimizing the presence of aromatics, naphthenics, nitrogen, and sulfur. The process involves reacting the feedstock with hydrogen under specific temperature and pressure conditions, utilizing a catalyst that includes a Group VIII noble metal. The resulting effluent undergoes fractionation to separate it into heavy, intermediate, and light fractions.

Another notable patent addresses the removal of sulfur compounds from hydrocarbon streams using adsorbents. This process is particularly relevant for gaseous hydrocarbon streams. It involves contacting the gas stream with a zeolite-based adsorbent to capture sulfur compounds, followed by a regeneration process that ensures the adsorbent can be reused effectively. The regeneration process is designed to maintain a relative humidity below 100%, enhancing the efficiency of sulfur removal.
