NGT Synthesis

NGT Synthesis is marketing Methaforming technology that enables oil refiners to produce high octane gasoline from naphtha streams at 1/3 of the current costs and emissions.

Based on proprietary research, Methaforming reacts a hydrocarbon stream in the ibp-200 C boiling range (the main feed) with methanol, (bio) ethanol or a mix of olefins or alcohols and ethers (the co-feed). The reaction takes place at low pressures (5-10 bar) and temperatures (about 380 C) over a proprietary catalyst. Due to colocation of exothermic (dehydration) and endothermic (dehydrogenation) reactions in the same reactor vessel, the heat requirements of the process are several times smaller than in a traditional reformer.

Methaforming also tolerates up to 1000 ppm of sulfur in the feed, and removes 90% of it, so e.g. a 100 ppm naphtha turns into a 10 ppm methaformate.

An example of the naphtha conversion by Methaforming is in the table below:

% by weight Naphtha feed Methaformate
n-Paraffins 30.0 6.4
i-Paraffins 29.0 27.1
Olefins 1.4 2.6
Naphthenes 31.4 21.9
Aromatics 8.2 42.0
Total 100.0  100.0

Methaforming’s economic and environmental advantage is particularly high when low value dry FCC gas (containing 20-30% of light olefins) is used as a co-feed.

Methforming can help refiners solve the issue of excess naphtha.
