Abstract

Synthesis Energy Systems Inc. (SES) enables its customers to advance gasification projects through commercial scale feedstock testing at its commercial scale coal to syngas facility in Zhao Zhuang City (ZZ Plant), Shandong Province, China. These tests help customers affirm individual project economic viability and reduce technology risk. Included in these test campaigns have been one and two-week long continuous operations at varying loads and on widely-varying feedstock such as Chinese Inner Mongolian lignite, Chinese sub-bituminous high ash (and high friable) coal, and Aus- tralian Queensland high ash sub-bituminous coal. Through these campaigns, SES has progressed one project into the detailed engineering and construction phase and one project into the feasibility study phase. SES believes that the abi- lity to perform these commercial scale campaigns without interruption of operation is unique to SES. The ZZ Plant, which sells clean syngas to a neighboring methanol facility, has been in operation since early 2008 on a design coal of high ash middlings (washery wastes) from ROM bituminous coal (30% - 40% wt ash). SES has made significant im-provements to the design, operation, and efficiency of the ZZ Plant and U-GAS technology that is licensed from Gas Technology Institute (GTI). Included in these is the Fines Management System (FMS), which has demonstrated overall carbon conversion of greater than 98%. The ZZ Plant consistently demonstrates fuel flexibility and greater than 98% availability, 98% carbon conversion, and 80% cold gas efficiency.

Summary

Introduction

SES is a global energy and gasification technology company that provides products and solutions to the energy and chemicals industries. SES operates in regions where low-rank coal and biomass feedstocks can be profitably converted into high-value products through the application of SES’ gasification technology. SES may partner with engineering, equipment and technology companies to provide its gasification technology package with an integrated modular product offering; invest in U-GAS (registered trademark of Gas Technology Institute) based projects either directly or through an investment partner; or acquire or partner with owners of low quality coal. SES’ proven gasification technology originated in the United States at the Gas Technology Institute (GTI) over 35 years ago. SES has a demonstrated track record of successfully implementing U-GAS with its first build-own-operate (BOO) project having over three years of successful operations and its second project on schedule
