About Synthesis Energy Systems, Inc.

A copper catalyst appears to be only slightly active at temperatures below 230 oC, and accelerated re-crystallization of the copper must be expected at temperatures exceeding 270 oC, there is only little tolerance in selecting the most favourable reaction temperature. Rising pressures favours CO and CO2 conversions: however, costs for equipment in the synthesis loop and syngas compressor move in opposite directions on the pressure in the synthesis reaction.

In general practice, un-reacted gas from the methanol synthesis reactor is recycled back to the reactor, thereby acting as a syngas quench cooler. The recycle ratio (recycle gas : syngas feed gas) is 3 : 1 up to 7 : 1 in normal practice.

Black liquor can be gasified and used for methanol synthesis.

Some heat is normally recovered and used for other parts of the synthesis.

Fuel diversification: from GtL to XtL
The estimated amount of natural gas reserves has continuously increased over the past ten years, moving from the 1997 estimation of 152.2 Tcm to 181.5 Tcm in 2007, with a reserve/production ratio of around 63 years, higher than oil of 38 years.1 It is thus quite logical to envisage using natural gas (or coal with its R/P ratio above 140 years) as a source of liquid transportation fuels, through natural gas conversion into liquid hydrocarbons, the so-called GtL, which is characterised by an intermediate step of natural gas conversion for producing synthesis gas (hydrogen and carbon monoxide).

Hydrogen Energy and Synthesis Gas (Syngas) Technologies

RECTISOL® is a physical acid gas removal process using an organic methanol-based solvent at subzero temperatures. RECTISOL® can purify synthesis gas down to 0.1 vppm total sulfur (including H2S and COS) and CO2 into ppm range. Commercial scale RECTISOL® wash units are operated world-wide for the purification of hydrogen, ammonia, methanol, syngas and for the production of high purity carbon monoxide.

Gasoline synthesis (TIGAS) | Haldor Topsoe

AB - The purpose of this study was to establish a fuel process for an advanced power generation system in which hydrogen-rich synthesis gas, as the fuel for the molten carbonate fuel cell (MCFC), can be extracted from biomass via gasification and reforming technologies. Experiments on waste wood gasification were performed using a bench-scale gasification system. The main factors influencing hydrogen generation in the noncatalytic process and in the catalytic process were investigated, and temperature was identified as the most important factor. At 950°C, without employing a catalyst, hydrogen-rich synthesis gas containing about 54 vol% hydrogen was extracted from feedstock with appropriately designed operation parameters for the steam/carbon ratio and the equivalence ratio. However, by employing a commercial steam reforming catalyst in the reforming process, similar results were obtained at 750°C.

Synthesis Gas - Gas Products | Linde US Engineering

First, rather than venting or combusting methane emissions, which would release 100% of the carbon emissions into the air, concentrated methane emissions are captured and inserted into Newlight’s polymerization system for material synthesis.

There are several common “non-gasification” processes that are used to produce synthesis gas (syngas) on an industrial scale. They are 1) Partial Oxidation, 2) Autothermal Reforming, and 3) Steam Methane Reforming.

This production can be divided into two main value chains:
• Production of methanol and methanol-derived products (including acetic acid, DME and so on)
• FT synthesis for production of high-quality middle distillates (ie, kerosene and diesel fuel), pure paraffinic naphtha, lube bases, waxes and, in some cases, olefins and speciality chemicals.
