A Pseudo Randomly Triggered Integer Cycle Control (PRT-ICC) for AC Loads to Reduce THD, EMI and RFI
Abstract: Several proportional voltage control techniques exist for AC loads. The most popular of these are phase control (PC), cycle control (CC) (including integral cycle control (ICC) and fractional cycle control (FCC)) and pulse-width modulation (PWM)). Phase control utilizes triggering for loads away from zero voltage or zero current and generates odd harmonics with amplitudes higher than ICC and PWM. Integral cycle control, causes more harmonics (both even and odd) overall …

Removal of Thiophene from Model Fuel Using Titanium Catalyst
Abstract: Organosulfur compounds like thiophene (Th) and its alkyl derivatives are the major unwanted species present in crude oil fractions as they lead to the formation of sulfur oxides after combustion of the fuel and these oxides of sulfur cause severe environmental damage. Oxidative desulfurization (ODS) process is considered as one of the best alternative deep desulfurization technologies compared to hydrodesulfurization. In the ODS process, the sulfur compounds are oxidized to …
