Biomass Sample

Mixed combustion of biomass and coal is a new combustion way of comprehensive utilization biomass and coal energy resources. Biomass is more volatile, lower combustion temperature, combustion is mainly concentrated in front, low calorific value and the use of value is limited. Coal is less volatile, high combustion temperature, combustion exothermic are mainly concentrated in coke combustion, and exothermic is high. Studying on the combustion process and the combustion characteristics of mixed combustion of biomass and coal is development technologies based of mixed combustion of biomass and coal. Choose two biomass sample Sawdust, confetti and a coal, analyze combustion characteristics to mixing sample of different ratio, to obtain combustion process of mixed sample, combustion performance impact of biomass to coal and calorific influence of coal to biomass.

Propylene Production

Propane dehydrogenation (PDH) has been a promising propylene production process that can compensate for the increasing global demand for propylene. However, Pt-based catalysts with high stability at ≥600°C have barely been reported because the catalysts typically result in short catalyst life owing to side reactions and coke formation. Herein, we report a new class of heterogeneous catalysts using high-entropy intermetallics (HEIs). Pt–Pt ensembles, which cause side reactions, are entirely diluted by the component inert metals in PtGe-type HEI; thereby, unfavorable side reactions are drastically inhibited. The resultant HEI: (PtCoCu)(GeGeSn)/Ca–SiO2 exhibited an outstandingly high catalytic stability, even at 600°C (kd−1 = τ = 4146 h = 173 d), and almost no deactivation of the catalyst was observed two months for the first time.
