An overview of solid base heterogeneous catalysts for biodiesel production Catal. Rev. Sci. Eng. (IF 11.389) Pub Date : 2018-07-11 Akshey Marwaha, Amit Dhir, Sunil Kumar Mahla, Saroj Kumar Mohapatra
The alcoholysis process requires high activity catalysts for biodiesel production. Heterogeneous catalysts have been proven to possess highly active nature and are environment-friendly. The present article emphasizes on various types of solid base catalysts that have been used in the recent past for the production of biodiesel by transesterification of oils. The parameters and conditions affecting

Olefin epoxidation with metal-based nanocatalysts Catal. Rev. Sci. Eng. (IF 11.389) Pub Date : 2018-07-03 Angelique Blanckenberg, Rehana Malgas-Enus
Alkene epoxidations are an important class of reactions carried out in industry; however, current methods are plagued by problems, including high cost, difficulty in recovering catalysts, and generation of large quantities of acidic and chlorinated waste. In recent years, nanocatalysts have been considered as robust, heterogeneous alternatives to homogeneous catalysts. This work evaluates silver- and

Carbonaceous materials modified catalysts for simultaneous SO2/NOx removal from flue gas: A review Catal. Rev. Sci. Eng. (IF 11.389) Pub Date : 2018-06-19 Kiman Silas, Wan Azlina Wan Ab Karim Ghani, Thomas S.Y. Choong, Umer Rashid
Globally, considerable effort and resources are being channeled toward controlling the rising threat from pollution and other related impacts from man-made activities, which have detrimental effects on human health and the environment. The presence of some associated gases such as nitrogen oxides and sulfur oxides in the flue gas interfering with the carbon capture processes are responsible for acid

Emerging role of nanobiocatalysts in hydrolysis of lignocellulosic biomass leading to sustainable bioethanol production Catal. Rev. Sci. Eng. (IF 11.389) Pub Date : 2018-06-11 Mahendra Rai, Avinash P. Ingle, Raksha Pandit, Priti Paralikar, Jayanta Kumar Biswas, Silvio Silverio da Silva
Catalytic conversion (hydrolysis) of carbohydrate polymers present in the lignocellulosic biomass into fermentable sugars is a key step in the production of bioethanol. Although, acid and enzymatic catalysts are conventionally used for the catalysis of various lignocellulosic biomass, recently application of immobilized enzymes (biocatalysts) have been considered as the most promising approach. Immobilization

Remote C-H bond activation/transformations: A continuous growing synthetic tool; Part II Catal. Rev. Sci. Eng. (IF 11.389) Pub Date : 2018-06-01 Ritika Sharma, Upendra Sharma
The selective functionalization of inert C-H bonds is always challenging due to their abundance and large bond dissociation energies. Despite recent advancements, the engagement of inert building blocks for distant functionalization is the most appealing approach for the past decade for the construction of complex molecules. Along with the upsurge of proximal C-H bond activation methods, the presence

Heterogeneous catalysts for hydrogenation of CO2 and bicarbonates to formic acid and formates Catal. Rev. Sci. Eng. (IF 11.389) Pub Date : 2018-06-01 Dmitri A. Bulushev, Julian R.H. Ross
Formic acid and formates are often produced by hydrogenation of CO2 with hydrogen over homogeneous catalysts. The present review reports recent achievements in utilization of heterogeneous catalysts. It shows that highly dispersed supported metal catalysts are able to carry out this reaction by providing activation of hydrogen on the metal sites and activation of CO2 or bicarbonate on the support sites
