One track to this is ‘pyrolysis’ in which natural gas is split into ‘white’ hydrogen and carbon black. This avoids the need for a massive roll-out of carbon capture and storage sites as envisaged in natural gas reforming or ‘blue’ hydrogen schemes

Experimental study on two-phase flow and thermal performance in pulsating heat pipes Proc. Inst. Civ. Eng. Energy (IF 1.1) Pub Date : 2021-08-16 Suchen Wu, Hua Zhou, Feng Yao, Zilong Deng, Yan Zhang, Shusen Jiang
Pulsating heat pipes have shown great potential in the field of engineering applications, such as the cooling of microelectronic devices. The correlation between the flow characteristics and the thermal performance of the heat pipe still needs to be further explored. In this paper, the operation state and flow patterns inside pulsating heat pipes with two inner diameters of 1 and 2 mm are experimentally

Improving biodiesel made from cottonseed and soyabean oil with partial hydrogenation Proc. Inst. Civ. Eng. Energy (IF 1.1) Pub Date : 2021-08-16 Derick Adu-Mensah, Deqing Mei, Lei Zuo, Shengchao Dai, Yaping Gao
Biodiesel limitations such as poor cold-flow properties and oxidation stability limit its usage in diesel engines. Partial hydrogenation is reported to be one of the ways to improve these limitations. Partial hydrogenation of biodiesel made from cottonseed and soyabean oil was studied. Before and after hydrogenation, the fatty acid methyl ester contents of cottonseed and soyabean biodiesel were detected
