| Open AccessSyngas to light olefins conversion with high olefin/paraffin ratio using ZnCrOx/AlPO-18 bifunctional catalysts
Developing robust catalysts for direct synthesis of light olefins from syngas remains a challenge. Here, the authors report a novel bifunctional catalyst composed of ZnCr binary oxide and low-Si AlPO-18 zeolite which exhibits enhanced CO conversion and selectivity to C2-C4 olefins under mild reaction conditions.

| Open AccessChina’s coal mine methane regulations have not curbed growing emissions
Chinese government has implemented regulations to reduce mining-related methane emission since 2010. Here the authors estimated methane emissions in China using GOSAT satellite observation and results reveal a business-as-usual increase in methane emissions since 2010 despite those ambitious targets.

| Open AccessLow carbon renewable natural gas production from coalbeds and implications for carbon capture and storage
Coalbeds produce natural gas, which has been observed to be enhanced by in situ microbes. Here, the authors add plant-derived carbohydrates (monosaccharides) to coal seams to be converted by indigenous microbes into natural gas, thus demonstrating a potential low carbon renewable natural gas resource.
